This page is an in-depth guide to some of the best all-in-one gyms and functional trainers on the market — The Force USA G-Series All-in-One Gyms, which include 7 different models. I’ve done in-depth reviews on them all:

NOTE: The Force USA All-in-One Gyms were formerly known as the Force USA Monster All-in-One Gyms. They have since taken out the “Monster” name to simplify the branding.

In this Force USA G3/G6/G9/G10/G12/G15/G20 review, I’ll tell you:

  • What are the Force USA G-Series machines
  • What makes them unique
  • Who they’re best suited for, and who they’re not for
  • The differences between the four G-Series models — and much more!

Originally, I was going to have the G3 shipped to my place so I could test and review it. However, that turned out to be impractical since I’m already low on space in my home gym.

Instead, I coordinated with Force USA to visit their Utah headquarters so I could thoroughly test out ALL of their all-in-one gym machines in person.

I can’t wait to share my insights and tons of photo & video footage in this review! But first, I’ll give a quick summary in case you’re looking for a fast answer:

Best all-in-one trainer if you're looking for a plate-loaded functional trainer that can switch between a 2:1 and 4:1 pulley ratio for heavier or lighter increments. It's more budget-friendly than its selectorized counterpart, the G15. It's also great for strength-focused lifters since they can use a lot more weight on the plate-loaded carriage than on a weight stack.

It’s a Functional Trainer… It’s a Rack… It’s the Force USA G-Series!

In terms of more traditional gym equipment, the Force USA G-Series would probably fall under the “functional trainer” category. The G-Series machines are all built around a functional trainer system.

However, the Force USA G-Series units offer so much more than the average functional trainer. They have more features and exercise stations beyond just a cable system.

You could more accurately describe the G-Series as all-in-one gyms.

What Is a Functional Trainer?

In case you don’t know what a functional trainer is, I’ll fill you in:

  • In its most basic form, a functional trainer is a single piece of equipment with two adjustable-height cable pulley columns.
  • The columns are typically between 3-5 feet apart (if they’re much further apart, it’s probably a “cable crossover” machine).
  • Resistance is added with a plate-loaded weight carriage or a selectorized weight stack system.
  • There is usually a chin up bar at the top of the machine.

Functional trainers get their name from the type of training they make possible: functional training.

Functional training, in the context of physical therapy or strength coaching, refers to resistance exercises that simulate everyday movements or sports-specific movements. Strength gains in these exercises transfer directly to better performance in the movements/activities being simulated.

Everyday movements and sports-specific movements can occur in any of the three planes of motion: sagittal, frontal and transverse. Some movements occur in two or all three planes.

Functional trainers are designed for multiplanar movement. Not only do they allow you to perform movements to train each of the three planes separately, but you can do movements that combine two or more planes of motion.

Functional trainers offer more variety and efficacy when it comes to functional training, compared to fixed-path resistance machines as well as free weights.

That said, functional training is NOT the be-all and end-all of resistance training. Far from it.

Next, I’ll discuss the G-Series features that address the other aspects of resistance training.

Force USA G-Series vs Other Functional Trainers

Force USAAll-in-One Gyms vs Dedicated Functional Trainers
Basic functional trainer (REP FT-3000) vs all-in-one gym machine (Force USA G6)

The vast majority of functional trainers on the market include just the cable tower portion and maybe a chin up bar at the top. They’re “basic” functional trainers. That is fine if that’s all you’re looking for.

However, the functional trainer market has evolved. People want more than just cable columns if they’re going to have a large piece of equipment taking up valuable space in their gym.

The Force USA G-Series uses the basic functional trainer as the foundation of its design. However, the G-Series goes far beyond a pair of cable columns and a chin up bar. The G-Series combines multiple workout stations to create an all-in-one gym for strength training.

The workout stations vary from model to model. However, all of the models have most if not all of the following exercise stations (most are included standard, but some are optional depending on the model):

  • Functional trainer
  • Power rack (technically a “half rack” but I’ll call it a power rack to be consistent with the product pages)
  • Smith machine
  • Multi-grip chin up bar
  • Dip station
  • Jammer arms
  • Leg curl/extension
  • Landmine / Core training station
  • Leg press machine
  • Low row station
  • Suspension trainer area

You can do all of the main lifts and potentially hundreds of exercise variations with this setup. Hence, why this system is not just a functional trainer, but an all-in-one gym.

Force USA G-Series Features & Specs: G3 vs G6 vs G9 vs G10 vs G12 vs G15 vs G20

All of the Force USA G-Series models share the same basic design and function. But there are some MAJOR differences between them. The easiest way to show you their similarities is with comparison tables. I’ll include three comparison tables below:

  • One table comparing major features/exercise stations
  • One table comparing technical specs

* The G9’s pulley ratio is 1:1 when using both sides of the functional trainer simultaneously. It is 2:1 when using one side at a time.
** On the G3/G9/G12, the cable will get in the way of the j-hook or safety spotter unless the pulley is above it. When the pulley is at the highest setting, it blocks the top hole on the G3, and the top 2 holes on the G9/G12. ALL holes are accessible on the G6 because the pulley can be above or below the j-hook or safety.
*** The retail price (MSRP) is shown in the crossed-out text. The actual price is shown below. Please note, that actual price is subject to change and may not be current.

Included Accessories Comparison

NOTE #1: I’ve modified the names of some of the cable accessories from what’s on their product pages or in their manuals. This is because I felt some of the names were unclear.

Who Should/Shouldn’t Buy the Force USA G-Series?

The Force USA G-Series was designed for specific use cases. It’s an excellent choice for some people. But it’s definitely not right for others.

Here’s who should consider the Force USA G-Series:

  • People with limited floor space for gym equipment who don’t want to sacrifice on versatility and exercise selection.
  • People who want access to multiple exercise stations, but don’t want to pay the higher price that several separate pieces of specialized equipment would cost.
  • Anyone buying gym equipment that will be used by family members who have diverse training styles and goals. Let’s take the example of a husband and wife who both do resistance training. It’s very common that the husband will want to do a lot free weight movements. Whereas, the wife will prefer doing a lot of Smith machine work. And they’ll both likely do a lot of functional trainer movements.
  • Personal training studios that take on a range of clients with different goals, ages and training capabilities.
  • Physical therapy practices that need a versatile resistance training solution to help rehabilitate clients recovering from injury or suffering from muscular imbalances.
  • Anyone seeking versatile gym equipment for fire stations, police stations or military bases. The G-Series machines provide more than enough versatility to handle the diverse resistance training needs of a small team or group of individuals. The G-Series (especially the commercial G9 and G12 models) are also capable of standing up to the rigorous use that such a group of physically active users would put it through.
  • Small local fitness centers or recreation centers that don’t have a ton of space for resistance training equipment. They may have a lot of cardio equipment, a large pool, or other amenities. But they’re lacking in strength and resistance equipment, and need a space-efficient solution.
  • Anyone looking for a complete training solution in a corporate gym, hotel gym or similar setting.

In contrast, the Force USA G-Series machines are not for:

  • Serious powerlifters or other strength athletes who need a full-sized power rack as the centerpiece of their gym.
  • Anyone who plans on building out their home gym meticulously, piece by piece, with several different machines.
  • Any high-traffic, big box commercial gym. These places have enough space and budget for many different specialized pieces of equipment. They have no need for an all-in-one gym solution.

Force USA G-Series Review: Pros & Cons

In this section, I’ll discuss the pros and cons that apply to ALL models. Later in this article, I’ll review each of the G-Series models with pros and cons that are specific to each model.

Since there are several pros and cons that apply to all of the units, this broad G-Series review section will allow me to avoid repeating myself too much in the individual G3, G6, G9, G10, G12, G15 and G20 reviews.

Force USA G-Series Pros

Space-saving

The Force USA G-Series racks are compact all-in-one gyms with between 5 to 17 exercise stations depending on the model and if you get all the upgrades. Plus, they all have weight, barbell and accessory storage — all in about the same footprint as a full-sized power rack!

This is perfect if you have a limited training space but don’t want to compromise on exercise variety.

Save Space with the Force USA G-Series All-in-One Gyms

Money-saving

None of the G-Series racks are cheap. But they all deliver A LOT of value for the money.

Part of the reason you’re buying an all-in-one gym is so you don’t have to buy several different pieces of equipment separately. That’s where major savings come. If you got bought specialized equipment to match all of the different exercise stations in any of the G-Series racks, you’d spend hundreds if not thousands of dollars more.

Versatile

The functional trainer portion of the G-Series gives you access to over 75 exercise variations. You can do hundreds of exercises when you add in the exercises made possible by the power rack, Smith machine, chin up bar, leg press, landmine and other stations.

I should also note that as of late 2022/early 2023, all G-Series models have access to jammer arms and a leg curl/extension attachment as part of an optional upgrade. The jammer arms, in particular, had been the #1 feature request from customers for years. Now, they’re a reality.

With so many standard and optional exercise stations, you’ll be hard-pressed to find an exercise that you can’t do. That’s the definition of versatility.

Accessory Storage

All G-Series racks have an accessory storage area. It looks different on every rack, but they all have plenty of hooks to hang the cable accessories that come with the rack.

Force USA G6 Accessory Storage

You can store multiple items per hook. So there’s room for the included accessories PLUS other accessories you may already have, like resistance bands, a lifting belt, lifting straps or anything else you can hang on a hook.

Some models, namely the G10 and G15, have the option to expand storage even further with shelves:

Force USA G15 Storage Shelves

Weight Plate Storage

There’s no need to buy a separate weight plate tree to store all your weights. There are weight storage pegs on all of the G-Series models, which can hold several hundred pounds of plates. The number of weight storage pegs ranges from 6 to 10 depending on the model.

Force USA G10 All-In-One Trainer - Weight Plate Storage

This weight storage solution is convenient since the storage pegs are on either side of the rack and a short distance from the smith machine, barbell or plate-loaded weight carriage. Plus, you make the entire unit more secure when you load hundreds of pounds of weight onto the frame. A nice side benefit!

All weight plate storage holders can hold either Olympic plates or standard plates. For standard plates to fit, you simply have to remove the grub screw and take off the Olympic sheath. This will reveal a skinnier peg that will fit standard plates.

Most people probably don’t need to store standard plates, but some will appreciate it. For example, it’s common for many home gym owners to have spin-lock dumbbells that use standard plates. These people can use one or two of the pegs to store these plates.

Barbell Storage

The barbell storage feature on all of the G-Series models comes standard and includes a spot for at least one Olympic barbell and one standard barbell. The newest models (G10, G15, G20) have two barbell storage areas standard. And you can add two additional barbell holders if you get the G20 Lat Row Station Upgrade.

You store the bars vertically by inserting one end into a sleeve near the base of the rack.

Barbell Storage on Force USA G12

The 2 bar storage areas that come standard on the G20 are a bit different. They are barbell hangers; each holds a single Olympic bar from the top:

Force USA G20 - Vertical Barbell Storage Hanger

Note that you’ll need extra ceiling clearance in order to store an Olympic bar because the bar will be higher than the max unit height when stored. Plus, you need a few extra inches to slide it in and out of the sleeve.

The minimum ceiling height you need to store a full-length Olympic barbell varies by model:

  • 8’2″ for the G3
  • 7’8″ for the G6
  • 7’11” for the G9
  • 7’11” for the G12
  • 7’7.75″ for the barbell hangers on the base unit (7’9″ for the barbell sleeves on the Lat Row Station Upgrade)

It’s not a big deal if you don’t have enough ceiling space to accommodate the bar — I have the same type of vertical bar storage on my MyRack power rack, and I don’t use it even though my ceiling is tall enough. I either keep my main barbell in the rack or store it horizontally on my wall-mounted 8-bar gunrack bar holder.

Laser Engraved Numbering

All racks have laser engraved numbering on the side of the uprights for the pulley height settings.

Laser Engraved Numbering on Force USA G-Series

This makes it easy to remember which height setting you use for different exercises.

Although these numbers are for the pulley settings, they’re also useful markers for remembering which j-hook and safety heights you use for free weight barbell exercises — despite the numbers not matching up perfectly with each j-hook hole.

Force USA Training App

Force USA Training App - Workout Programs

When it comes to the G-Series from Force USA, it’s easy to feel a tad overwhelmed. With so many exercise options and configurations, both potential buyers and current owners might wonder, “Where do I even start?”

For some, this vast array of choices might even be a hurdle to buying. And for those who’ve taken the plunge, there’s always that nagging question: “Am I getting the most out of my machine?”

This is where the Force USA Training App steps in. It doesn’t just list exercises you can do with the G-Series; it’s more like a personal trainer in your pocket.

The app is tailor-made to get the best out of these machines, showcasing routines and exercises perfect for whichever G-Series (or X-Series) model you’ve got.

After giving the app a test drive myself, here are the highlights:

  • Workout Program Library: No matter your fitness level, there’s a workout here for you. From beginner to pro, the app’s got plans to suit your particular training goal.
  • Exercise Library: This is a gem. Loads of clear videos showing all the common and not-so-common exercises you can do on the G-Series machines. It’s great for those “How do I do that?” moments.
  • Progress & Performance Tracking: This feature lets you see your growth over time. Your past workouts, your best lifts, all laid out. Plus, the “Program Pyramid” on the home screen gives a snapshot of how consistent you’ve been.
  • User-Friendly Design: Simple, intuitive, easy to navigate. It’s clear that they designed this with the user in mind.
  • Workout Flow: It’s like having a personal trainer guiding you. Pick a workout, start it, and the app takes you through step by step. Adjust weights and reps on-the-fly, and then tap to head to the next set or exercise.
  • Rest Timer: No more guessing or losing track of time between sets. Finish a set, and the app lets you know when to get going again.
Force USA Training App - Workout Flow

But it’s not all sunshine and rainbows. One thing I noticed: you can’t craft your own custom workout from scratch. If you’re someone with a specific regimen, this will be limiting. But the extensive exercise library is still a goldmine for ideas.

While I’m partial to my own way of tracking workouts (good old Google Sheets!), I can see how this app would be a treasure for anyone with a G-Series.

Force USA G-Series Cons

An All-In-One Gym Is Not Specialized Equipment

You lose out on the benefits that come from having a dedicated piece of equipment for each exercise station when everything is combined into an all-in-one gym machine. For example:

  1. You’d be able to walk out a squat further if you had a full-sized power rack vs the half rack on the G-Series machines.
  2. You could get into position easier and have more foot placement options if you bought a dedicated 45-degree leg press machine compared to using the vertical leg press attachment on the G-Series units.

This is a given when you get any type of all-in-one tool (e.g. Swiss Army Knife). You make some small sacrifices for the benefit of space savings, budget, versatility and convenience.

Not a Cheap Purchase

Although you save a lot of money buying a G-Series machine instead of several dedicated pieces of equipment, the price is not cheap in absolute terms.

At the time of updating this article, the least expensive unit (G3) starts at $1,999 and the most expensive unit (G20) goes for $5,999 — and that’s without any optional upgrades. Of course, if you’re in the market for a quality all-in-one gym and functional trainer, you probably already knew it wasn’t going to be a small purchase.

On the bright side, my Force USA discount code KING5 will take 5% off you order.

No Model Has ALL the Best Features

There is no single unit with ALL of the best features, in my opinion. I found myself wishing that I could take one feature from one of the units and add it to another unit to make it “perfect” in my eyes.

For example, my ideal “Frankenstein” G-Series rack would be the G6 combined with the dedicated low-row station of G9 combined with the Westside hole spacing of the G3, plus the added width of the G9 and G12.

UPDATE: The above was true before the G20 was released. However, the G20 comes pretty close to having all the best features combined into the same unit. It’s pretty much exactly what I described as “my ideal Frankenstein G-Series rack” when I originally wrote this section. That’s not to say the G20 is perfect, but it took all the best features from the other units and integrated them into its design.

Force USA G3 Review

Force USA G3 Review

The Force USA G3 is a 5-in-1 machine, with the ability to upgrade to a 10-in-1 machine when it’s fully maxed out.

Force USA G3 Pros

Westside Hole Spacing

Westside hole spacing gives you hyper-precise 1″ hole spacing in the bench region and 2″ hole spacing in the squat region of the power rack.

Westside Hole Spacing on Force USA G3

Powerlifters usually care about this feature most, since having the perfect j-hook height for bench and squat can make the difference between hitting or missing a new personal record.

Band Peg Holes

Another reason why the G3 is perfect for powerlifting-focused trainees is its band peg holes.

Force USA G3 Band Peg Holes

They allow you to do all types of band-resisted exercises — with the barbell or Smith machine — such as band squats, band bench, band deadlifts, and even band-resisted pull ups. You can even add band tension to the pulleys — However, you need to be careful to balance the tension evenly on the left and right sides of the weight carriage for the pulley motion to remain smooth.

Better J-hooks

I personally like the j-hooks on the G3 better than the j-hooks on all other models except the G20.

Force USA G3 J-hook

Unlike most of the other G-Series models, there is a protective lining on the back surface of the G3 j-hooks. It will protect your bar better if you rack it against the rear surface.

Lowest Price

The G3 is the least expensive G-Series model by hundreds of dollars. This is even the case if you buy all the major optional accessories.

Pick & Choose the Attachments You Want

The G3 is the only model where you can pick and choose some of the major attachments you want to buy since they’re sold separately. This will save you money if you don’t want everything, compared to if everything was included by default.

More recently, Force USA expanded its catalog of attachments for the G3 by offering jammer arms, dip handles and a leg curl/extension attachment — but these must be purchased bundled in the G20 upgrade kit. Though, I should note that if you want just the leg curl/extension attachment, you can buy that one individually here.

Pulley Cables Extend Far

You can extend both pulley cables a full 12.1 ft, or 145″, in front of the rack. This lets you do some unique exercises such as walking cable lunges, cable sled pulls and many others.

This gives you more cable travel than any other unit. Here’s how they compare:

  • G6 = 60″
  • G9 = 51.5″ (or 103″ if using a single cable)
  • G10 and G15 = 60″ when using the 2:1 ratio (120″ on the 4:1 ratio)
  • G12 = 53″
  • G20 = 106″

Stabilizer Bar

The G3 is the only G-Series model with a stabilizer bar for the functional trainer.

Force USA G3 Stabilizer Bar for Functional Trainer

This attachment is great for stabilizing your body in the perfect position for different cable exercises. You can focus on the target muscles instead of your stabilizer muscles. It can also hold your legs in place for lat pulldowns if doing them in the center of the rack.

Knurled Chin Up Bar

Force USA G3 Chin Up Bar Knurling

The G3 is one of the only G-Series models with knurling on the steel portions of chin up bar — the G10 and G15 also have it. It’s passive knurling, but it nonetheless makes gripping onto the bar easier.

Spotter Arm Length

The safety spotter arms on the G3 are longer than the ones on all the G-Series machines. They’re 17.5″ vs 15″ for all others. These extra few inches let you step a bit further away from the uprights when walking out your squat.

Bolt-down

The Force USA G3 can be bolted down for additional stability, though it is not necessarily required.

Force USA G3 Bolt-down Option

Most people will find their rack is very secure without bolting it to the floor, especially if they have a lot of plates on the weight storage pegs.

Still, having the option to bolt it down is nice if you want to ensure it never shifts on the floor. If you plan to use the band pegs for heavy band squats or deadlifts, bolting it down will ensure the rack won’t budge.

Force USA G3 Cons

The Top J-hook Hole Is Inaccessible

The pulley must be set higher than the j-hooks. When the pulleys are in the highest possible position, the uppermost hole is blocked. Luckily, you can still set the j-hooks very high — the barbell will be 66″ (5’6″) above the floor when the j-hooks are at the highest possible spot. This means almost anyone will be able to squat comfortably unless they’re over 6’10”-6’11”. Still, it’d be better if the top hole was available.

No Suspension Trainer Ring

The G3 is the only G-Series model without a suspension trainer ring. However, you could attach a suspension trainer to the multi-grip chin up bar attachment as a workaround.

No Low Row Attachment

There is no attachment that’s designed specifically for use on low rows. However, you can improvise with band pegs and/or you can use the long bar attachment and put your feet on the rack, as shown below:

Who Is the Force USA G3 Best for?

The Force USA G3 is for anyone in the market for an all-in-one gym who places a strong emphasis on strength or powerlifting style training. The main features that make it ideal for this type of lifter are the Westside hole spacing and the band pegs.

It’s not just powerlifters who will prefer this model. The Force USA G3 is also a great fit for any type of fitness enthusiast seeking a budget-friendly all-in-one home gym solution. The G3 is the most affordable G-Series model by $1,000 (before you account for any optional G3 attachments).

The Force USA G3 is also a great model to consider for very tall lifters (as are the Force USA G6 and G20). The G3 has an internal height of 85″, which allows anyone under 7’1″ to work inside. As for doing barbell squats in the G3 rack, you can set the barbell as high as 66″ (5’6″) above the floor when the j-hooks are in the highest accessible setting. That’s high enough for lifters up to 6’10”-6’11” to squat without issue. In comparison, the G9 and G12 racks are only practical for squatting with lifters 6’5″ and under.

  • Cable Crunch Attachment
  • Lat Pulldown Bar
  • Metal Stirrup Handles (2)
  • Triceps Rope

  • Close Grip Row Handle

Force USA G6 Pros

Cool Accessory Storage

The G6 has a pretty cool accessory storage feature. It includes a swivel board with storage hooks on one side and an exercise chart on the other side. You can flip it around whichever way you want.

Force USA G6 Storage Area

There are enough storage hooks to hold all the included cable accessories, plus several other accessories you may have in your gym.

Selectorized Weight Stack

The G6 has selectorized weight stacks. You can change the weight much faster than with a plate-loaded system. This is perfect for doing drop sets, supersets, circuit training or training with a partner.

Lowest-cost Selectorized Model

If you want a selectorized all-in-one gym instead of a plate-loaded one, but you’re still on a budget, the G6 is for you. It costs $3,499, which obviously isn’t cheap. But it’s significantly less expensive than the other selectorized models (G12, G15, G20) by $1,000 to $2,500.

Band Peg Holes

The band peg holes on the base of the Force USA G6 allow you to do band-resisted movements, such as band squats, band bench and band deadlifts. You can also use it to add tension Smith machine exercises and even bodyweight movements like dips and pull ups.

One cool trick is to use band pegs to wrap a band over the weight stack:

Adding Band Resistance to the Selectorized Weight Stack on the Force USA G6

This lets you increase the max capacity of the stack by adding band tension. This is particularly handy because each 220 lb weight stack maxes out at 110.5 lbs or resistance (because of the 2:1 pulley ratio). Adding bands allows you to continually progress on heavier cable exercises like lat pulldowns and cable rows.

Better Than the Old (Pre-2019) G6 Model

The new G6 has better smith machine sleeves, a better dip attachment that now comes standard, a better leg press attachment that also comes standard, an improved weight storage solution and a better accessory storage area.

Better Pulley Position

The pulleys are just to the inside of the uprights. This is unique to the G6 vs most other G-Series models. What’s great about this position is the cable is NEVER in the way of the attachments. Importantly, the pulleys can be set above OR below the j-hooks and safety spotters.

Force USA G6 Has a Better Pulley Position - Pulley Can Go Below J-hooks

This means the uppermost j-hook holes are accessible, unlike some of the other models. As such, even super-tall lifters can squat without having to bend their knees too much to unrack.

The G10 and G15 also have their cables positioned so they don’t interfere with the power rack holes. The difference vs the G6 is that the G10/G15 pulleys are positioned to the outside of the uprights, rather than to the inside.

Bolt-down

The Force USA G6, like the G3, gives you the option to bolt it to the floor for additional security.

Force USA G6 Bolt-down Option

This is unnecessary for most people since the G6 is very heavy. It always has 440 lbs of selectorized plates in the back; plus the weight of the frame and all components; plus any weight plates you have stored on it.

That being said, bolting down will prevent even the slightest shifting from happening over time. It also guarantees the unit will remain stable even if you’re using the band pegs for band deadlifts or band squats using super high-tension bands.

Force USA G6 Cons

Narrowest Model

The G6 is the narrowest G-Series model. It has 41″ of width between the uprights in the power rack and 36″ in the Smith machine area. Luckily, this is enough area to do almost all the exercises you’d need to. Even with a super wide grip, you shouldn’t have any issues with barbell bench pressing in the power rack area, which is most important for me. The only issues that may occur would be with an extra wide bench press grip in the Smith area, or if you were to do a very niche exercise like snatch grip rack pulls in the power rack area.

3.75″ Hole Spacing

Generally, the closer the power rack holes are spaced, the better. Tight hole spacing lets you positing the j-hooks, spotter arms and other attachments exactly where you want them. It’s better for safety and performance.

The G6’s 3.75″ hole spacing leaves room for improvement. There will be times when have to position your j-hooks a little higher or lower than you’d like. Don’t get me wrong — it’s still adequate, it’s just not optimal.

Missing a Couple of Features From the Old G6 Model

The previous version of the G6 had a couple of cool features that I personally wish they would have kept in the new G6: knurling on the chin up bar and Westside hole spacing. That said, the new G6 is overall a big improvement over the old version.

Who Is the Force USA G6 Best for?

The Force USA G6 is the best choice for a few different groups of people.

  • Bodybuilders: The Force USA G6 is ideal for bodybuilding-focused training, mainly due to the selectorized weight stacks that enable rapid weight changes and allow you to integrate drop sets and supersets. The G6 also has band peg holes by the weight stacks. This lets you add band resistance to make the weight stacks even heavier.
  • Tall Lifters: The G6 is one of the best models for tall lifters, along with the G20 and G3. Its internal height is 85 inches, which is 5″ higher than the G10/G15 and 6″ more than the G9/G12. The max j-hook height is 69″ from floor to barbell, which is higher than on most models. Even the tallest of lifters can set the bar high enough for squats. Lastly, the G6 is tall enough for most lifters to get a full stretch on lat pulldowns while seated on a bench.
  • Budget-conscious lifters who need weight stacks: The G6 isn’t cheap in general. And it’s not even the cheapest G-Series model. However, it is the most affordable G-Series models with selectorized weight stacks.

In my opinion, the Force USA G6 is my second pick for the best overall G-Series model. It was my top pick until the Force USA G20 came out and took the top spot in my mind. Still, the G6 has an excellent mix of high-value features and a reasonable price considering it’s a selectorized model.

Force USA G9 Functional Trainer Accessories

  • Lat Pulldown Bar
  • Nylon Stirrup Handles
  • Long Straight Bar
  • Triceps Rope

Force USA G9 Pros

Dedicated Low Row Station

The Force USA G9 is the only G-Series model with a dedicated low row station inside the machine. It has a built-in steel foot pate that will keep you in a strong and stable position while rowing. If you love back training, this feature may make the G9 your best choice.

Compact

The Force USA G9 is the most compact plate-loaded G-Series model. It’s even more compact than some of the selectorized models, including the G6 and G20. It has a depth footprint of just 57.5″. If your top priority is conserving space and you’re leaning toward a plate-loaded option, this unit should be at the top of your list.

1:1 Pulley Ratio

You get one pound of resistance for every pound you load on the G9’s pulley weight carriage. Compare this to the 2:1 pulley ratio on the G3, which gives half a pound of resistance for every pound loaded on. This means you can load more total weight on the G9 pulley, faster.

Note that the pulley ratio on the G9 is only 1:1 when you’re using the pulley in the dedicated low row station (in the back of the machine), or when you’re using both sides of the functional trainer at the same time.

However, it’s a 2:1 ratio if you’re using just one side of the functional trainer. The reason that the ratio halves when using just one side is that the pulleys are connected to a single weight carriage.

Wide Uprights

The uprights are positioned 52″ apart, providing the maximum possible distance while still allowing for the use of a barbell on the power rack (with j-hooks offset inward for extra clearance). The G12 is the only other unit that’s this wide. All the other models are narrower by a few inches.

This extra width comes in handy when using the functional trainer for exercises cable fly and cable crossover exercises. You feel a greater stretch in your chest muscle fibers.

Reinforced Frame

The G9 has a more robust design than the G3 and G6 thanks to the reinforcement plates on the base and top of the frame. It is better able to withstand wear and tear in light commercial settings. It’s perfect for small fitness centers and rec centers, as well as small gyms in fire departments, police departments and military bases. It’s great for your home, too, if you want a beefier machine. However, after the G9 was released, Force USA came out with other options like the G20, G15 and G20 that are sturdier because they use thicker steel in the uprights.

Counterbalanced Smith Machine

The G9’s counterbalanced Smith machine gives the empty Smith bar a starting weight of 0 lbs. Non-counterbalanced Smith machines, like the ones on the G3, G6 and G20, have a starting weight of 45 lbs. This makes the G9 great for completely novice trainees who may not be strong enough to handle the 45 lb bar on some lifts.

Force USA G9 Cons

Can’t Do Incline Smith Machine Exercises

One of the drawbacks of the G9 being so compact is that there isn’t enough space inside the unit to set up an adjustable bench for incline Smith machine exercises. The issue is that you have to push the bench far enough back so that you’d be under the Smith bar with proper hand/shoulder position. Unless you have a very particular type of weight bench, this isn’t possible.

Floor-Seated Lat Pulldowns May Be Necessary

The G9 is one of the shorter G-Series models. A consequence of this is that you won’t be able to fully extend your arms at the top of the range of motion on lat pulldown when you’re sitting on a bench. That is, unless you’re short yourself. The workaround is to do lat pulldowns while seated on the floor. It’s not as convenient, but it provides just as good of a back workout.

Uppermost 2 J-hook Holes Are Inaccessible

The G9 design requires the pulleys to be above the j-hooks. When the pulleys are at their highest position, they block the top two holes. The highest you can set the barbell above the floor is 60″ (5ft). Tall guys (i.e. over 6’4″-6’5″) will have to bend their knees more than they’ll want to when setting up for squats.

No Westside Hole Spacing

Powerlifters may be disappointed that the G9 has 3.75″ hole spacing instead of precise Westside spacing (1″, 2″). Luckily, most other types of lifters won’t mind at all. If precise hole spacing is a requirement for you, check out the G3, G10, G15 and G20.

No Band Peg Holes

The lack of band peg holes on the G9 might also disappoint you if you’re seriously into powerlifting-style training. But if you’re not into that type of training, you probably don’t care about doing band squats, band bench or other banded training. If you need to have band pegs, check out the G3, G6 and G20. The G10 and G15 also have band peg holes, but they’re only usable for the Smith machine region.

Who Is the Force USA G9 Best for?

It’s easy to overlook the Force USA G9 because it doesn’t have the instant draw of a selectorized weight stack. Yet it’s also not the least expensive model. BUT I consider it the best value model considering its price relative to its build quality and features.

The Force USA G9 is a great fit for the following types of people or applications:

  • Home gym lifters who are serious about strength training, but don’t need special features like Westside hole spacing, band pegs or a selectorized weight stack. The G9’s plate-loaded system saves you ~$500-3,000 compared to the G6, G12 and G20 selectorized weight stack systems. And even though it doesn’t have “powerlifting features” like band pegs or Westside hole spacing, it does give you a high-quality machine with premium features for serious strength training (e.g. extra wide uprights, 1:1 weight ratio, fixed low row station, counterbalanced Smith machine).
  • Anyone who puts a major emphasis on back training. The dedicated low row station will make it worthwhile for these lifters.
  • Lifters who want premium features without breaking the bank: The G9 is the second lowest-priced G-Series model. Yet, it still has premium features like smooth pulley motion, a dedicated/fixed low pulley inside the rack for rows, a counterbalanced Smith machine and a reinforced frame.

  • Lat Pulldown Bar
  • Triceps V-Bar

  • Nylon Stirrup Handles (2)
  • Adjustable Nylon Stirrup Handles (2)

Force USA G10 Pros

Interchangeable Pulley Ratio (2:1 & 4:1)

The G10, like the G15, can switch between a 2:1 and 4:1 pulley ratio on the functional trainer. This allows you to use heavier total weight with 5 lb increments when using the 2:1 ratio; or lighter total weight and 2.5 lb increments when using the 4:1 ratio.

Force USA G15 - Interchangeable 4:1 and 2:1 Pulley Ratio on the Functional Trainer

This is made possible with a design that has 2 cables on each pulley. You connect your cable attachment to both cables to use the 2:1 ratio. Or attach it to just one of the cables to use the 4:1 ratio.

This feature also makes it quick to do drop sets on the G10, despite it being a plate-loaded system.

Ideal for Low Ceilings

The G10 is 87″ at its highest point, making it the shortest G-Series rack (along with the G15). This is a benefit for anyone with low ceilings (e.g. basement lifters) where every inch of clearance matters. a top choice if you’re ideal if you have low ceilings

Strong Frame

The G10 uses thick 11-gauge steel for its uprights, which makes for a more sturdy frame overall. This same as the same thickness of steel that the G20 and G10 use. All other units use slightly thinner 12-gauge steel for their uprights.

1″ Hole Spacing

The Force USA G10 is designed with 1″ hole spacing on the power rack uprights. This ensures you can be as precise as you need to be when installing attachments on the rack.

Force USA G10 Power Rack Uprights with 1 Inch Hole Spacing

Precision is particularly important when it comes to installing the j-hooks. This is because having the j-hooks installed too high or too low for your body can negatively impact both performance and safety. The heavier you’re lifting, the more important it is to have the j-hooks at the right height for unracking and racking the barbell.

Counterbalanced Smith Machine

The Force USA G10 Smith Machine is designed with a counterbalance system. This system balances the weight of the Smith bar, making it weigh zero pounds when unloaded, as opposed to its actual weight of 45 pounds.

A counterbalanced Smith machine is helpful for users who may not be strong enough to lift at least 45 pounds on certain exercises. This could include novices, children or individuals rehabbing an injury.

Multiple Leg Press Plate Angles

The G10 Smith machine features three holes on its hooks, which provide three distinct angles for the leg press plate.

Force USA G10 Leg Press Angle Settings

By choosing the most comfortable angle for your body, you can get into a natural position. You’ll be able to concentrate more on the movement and less on stabilizing the leg press plate or worrying about the Smith hooks knocking into the pegs on the safety catch system.

Force USA G10 Cons

May Need to Sit on the Floor for Lat Pulldowns

While users with low ceilings will appreciate the G10’s short height, one drawback is that you can’t do full range of motion lat pulldowns if you’re sitting on a weight bench — unless you are short. Instead, you’ll have to have to do floor-seated lat pulldowns to get a full stretch. The same happens on other shorter units like the G9, G12 and G15.

Force USA G10 Lat Pulldown Station - Floor-Seated vs Bench-Seated Lat Pulldowns

Leg Press Not Included Standard

The leg press attachment is only available in the upgrade kit. It comes standard on all other models except the G10 and G15.

Who Is the Force USA G10 Best for?

The Force USA G10 makes sense for multiple scenarios. Here are some of the best use cases:

  • Powerlifters: If you do powerlifting-style training and want an all-in-one trainer for your home gym, the G10 is a solid choice. It has precise 1″ hole spacing which powerlifters care about. Plus, it’s a plate-loaded unit, which allows powerlifters to use more resistance than with a selectorized model; it’s just a matter of loading on enough plates.
  • Family use: The G10 is a great choice for couples or families who will all be using it. Typically in this scenario, you have a mix of different strength levels; some strong lifters and some relatively weak. The ability to change between a 2:1 and a 4:1 pulley ratio will satisfy all everyone’s needs.
  • Gyms with low ceilings: The G10 is tied with the G15 as the shortest G-Series model. If you have short ceilings, the G10 should be on your shortlist (no pun intended).

Force USA G12 Pros

Most Compact Model

The Force USA G12 stands out as the most compact model among the G-Series, boasting a compact depth footprint of just 53 inches. It doesn’t require any additional space in the back, allowing you to position it flush against a wall. If you’re seeking to optimize your gym equipment’s footprint, the G12 offers a perfect solution for maximizing space efficiency.

Selectorized Weight Stacks

Force USA G12 Selectorized Weight Stacks

Changing the resistance on the functional trainer is fast and easy with the G12. You just move the selector pin up or down in the weight stack to decrease or increase the weight.

1:1 Pulley Ratio

If you select 100 lbs on the weight stack, the resistance will be 100 lbs. Compare this to the G6’s 2:1 pulley ratio where you’ll get just 50 lbs of resistance when you select 100 lbs.

Wide Uprights

The G12, like the G9, features extra-wide uprights that measure 52″ from outside to outside. It’s so wide that the j-hooks and spotter arms need to be offset to the inside to accommodate a barbell on the power rack. The other G-Series models have notably narrower uprights.

The extra width is beneficial for exercises like cable fly and cable crossover because you can spread your arms further apart and get a more intense chest stretch.

Reinforced Frame

The G12 is designed for more rigorous use compared to at least the G3 and G6. It has a reinforced frame that you can see at the base of the frame and along the top sides. This makes it suitable for certain light commercial settings, such as personal trainer studios, physical therapy practices, hotels and corporate gyms, among other places.

Counterbalanced Smith Machine

This gives the empty Smith bar a starting weight of zero pounds. This is perfect for untrained individuals who might be too weak for the 45 lb starting weight on the non-counterbalanced Smith machines found on the G3, G6 and G20.

Force USA G12 Cons

Large Increments

While the 1:1 pulley ratio is great for having a high max weight for heavy exercise, the downside is that the weight increments are also heavier. The lightest possible weight (no pin inserted is 10 lbs. And each subsequent weight setting increment is 10 lbs.

Jumping 10 lbs per weight setting can be too challenging on lighter exercises (e.g. lateral raises) and/or for novice lifters. Luckily, you can buy 5 lb add-on weights to put on top of the stack to achieve 5 lb increments.

No Incline Smith Machine Exercises

Due to its compact design, the G12 does not have enough room inside to slide an adjustable bench far enough back for incline Smith machine exercises. At least, that’s the case with most benches. It’s possible there may be some benches out there that could fit, but even that would be an extremely tight fit and it likely would force your shoulders into a very flared-out position. My point is that you shouldn’t expect to be able to incline Smith work if you buy the G12. This is the same issue as on the G9.

May Need to Sit on the Floor for Lat Pulldowns

If you’re short, you can probably disregard this. But most people (or at least most male lifters) will need to do floor-seated lat pulldown in order to achieve a full stretch at the top of the range of motion. If you try doing lat pulldowns while sitting on a bench, you’ll more than likely hit the pulley before your arms are fully extended. This is because the G12 is among the shorter G-Series models, along with the G9, G10 and G15.

It may be annoying to get into position for floor-seated pulldowns, but that doesn’t take away from their efficacy.

Top 2 J-hook Holes Are Inaccessible

The pulley design requires that the pulley must always be above the j-hooks. When the pulley is in the highest position, it blocks the uppermost two holes. This makes it so the highest you can set the bar for squats is 60″ (5ft). Taller guys — especially those over 6’5″ — will have to bend their knees more to get under the bar for squats.

No Westside Hole Spacing

If you’re a serious powerlifter, having uniform 3.75″ hole spacing instead of Westside hole spacing (1″, 2″) may be a little disappointing. In which case you should look at the G3, G10, G15 and G20. If you’re any other type of lifter, the G12’s hole spacing will be fine.

No Band Peg Holes

There are no band peg holes, which means you can’t do any band-resisted exercises like band squats or band bench. However, this is a niche feature that mostly powerlifter types really care about. If band work is a must, look at the G3, G6 or G20. The G10 and G15 also have band peg holes, but it’s important to note you can only use them on the Smith machine.

Who Is the Force USA G12 Best for?

There are several different applications where the Force USA G12 is a great choice:

  • Physical therapy practices and personal training studios: The G12’s selectorized weight stacks allow for quick weight changes, saving valuable time in client sessions with time limits. It also has a counterbalanced Smith machine that weighs nothing when empty, making it suitable for beginner, elderly, or injured clients who need to use lighter weights.
  • Bodybuilding or serious strength training (but not necessarily powerlifting): The G12 makes sense for home gym owners who want a high-end setup for bodybuilding or general strength training. It has a heavy selectorized weight stack system, making weight changes quick and efficient. The weight stacks are particularly helpful for bodybuilders as they facilitate drop sets, supersets, and giant sets. The 1:1 pulley ratio makes it ideal for serious strength trainees. However, it may not be suitable for powerlifters who require band peg holes or precise power rack hole spacing.
  • Anyone who wants a 1:1 pulley ratio on the functional trainer: Ever since the G20 redesign, the G12 is the only G-Series model with a 1:1 ratio on each side of the functional trainer (the G9 has a 1:1 ratio, but only when using both sides together, or when using the low pulley in the back of the unit). If you’re worried about the large 10 lb increments that come with a 1:1 ratio, just realize you can buy add-on weights that sit on top of the weight stack to give you 5 lb increments.

Force USA G15 Pros

Note: The Force USA G15 shares (most of) the same pros as the G10 since they are the same except that the G15 is selectorized and the G10 is plate-loaded.

Selectorized Weight Stacks

The G10 functional trainer uses a selectorized weight stack system featuring a pair of 289 lb weight stacks. The selectorized system makes adjusting the weight near-instant by simply moving the pin in the stack. It’s a more seamless training experience than with a plate-loaded system.

Force USA G15 Functional Trainer Weight Stacks

Additionally, a selectorized setup takes up less space compared to plate-loaded setup. This is why the G15 has a 20″ smaller depth footprint than the G10.

Interchangeable Pulley Ratio (2:1 & 4:1)

The Force USA G15 has the ability to change between a 2:1 and 4:1 pulley ratio. This is accomplished with a design that has two cables coming out of each pulley. To use the 2:1 ratio, you connect your handle to both cables. For the 4:1 ratio, you connect your handle to just one cable.

Force USA G15 - Interchangeable 4:1 and 2:1 Pulley Ratio on the Functional Trainer

With the 2:1 ratio, you have the option to use a heavier total weight in increments of 5 lbs. On the other hand, the 4:1 ratio allows for lighter total weight with more precise 2.5 lb increments.

This is very popular for families or couples who will be using the machine. The 2:1 ratio is better for the stronger lifters and the 4:1 is preferred by the weaker lifters. Of course, both ratios can be beneficial for all levels of experience — it all depends on the exercise being done.

Ideal for Low Ceilings

The G15 is tied with the G10 for being the shortest G-Series model. It is 87″ tall at its highest point. If you’ll be putting your all-in-one gym in a room with short ceilings, you should strongly consider this model. For example, if you only have 8-foot ceilings, the G15 will not only fit in the room, but you’ll have enough overhead clearance to do full range of motion pull ups.

Strong Frame

The G15 is one of just three G-Series models to feature 11-gauge steel uprights; the other two being the G10 and G20. All of the other models use thinner 12-gauge steel. While all the models can handle ~1000 lbs on the power rack, the 11-gauge steel makes for a slightly sturdier build quality.

1″ Hole Spacing

The Force USA G15 has close 1″ hole spacing that allows you to attach your power rack attachments exactly where you want them.

Force USA G15 Power Rack Hole Spacing

This precise spacing is helpful for getting the perfect placement of the j-hooks. When you’re using heavy weight on an exercise like the barbell bench press, having the j-hooks where you need them is not just safer, but it improves performance.

Counterbalanced Smith Machine

The Force USA G10 Smith Machine is counterbalanced, meaning it feels weightless when not loaded.

This comes in handy for any exercise where you want to lift less than 45 lbs. It’s most beneficial for novice lifters or anyone rehabbing an injury.

Multiple Leg Press Plate Angles

The G10 Smith Machine gives you the ability to choose from three different leg press plates. This is done by inserting the pop-pin on the plate into one of the three holes on the Smith machine hooks. The G10 is the only other model with this capability.

Force USA G15 Leg Press Angle Settings

The benefit of this feature is you can find an angle that feels more natural for your ankles and hip mobility. You don’t have to focus as much on stabilizing the plate.

Force USA G15 Cons

Note: The Force USA G15 shares (most of) the same cons as the G10 since they are the same except that the G15 is selectorized and the G10 is plate-loaded.

Lat Pulldown Range of Motion

A downside of the G15’s short height is that you have less range of motion on lat pulldowns. Unless you’re short, you’ll find that you can’t do lat pulldowns with full range of motion while seated on a bench. Your arms will still be bent at the top of the motion.

If you want to get full extension and a good stretch in your lats, you’ll need to sit on the floor for lat pulldowns. Floor-seated are just as effective, but it’s not as convenient or comfortable as sitting on a bench.

Leg Press Not Included Standard

The leg press is sold separately as part of the optional upgrade kit for the G15. Most other G-Series models include the leg press plate standard with the base unit. So if you wanted a leg press out of the box, this may be disappointing.

No Band Peg Holes in Weight Stack Area

The G15 does have band peg holes on the base of the rack. But unfortunately, they’re only in the Smith machine region. As a consequence, it’s not easy to add band resistance to the weight stack to go beyond the max resistance of 144.5 lbs for each weight stack. In contrast, the G20 comes with integrated mini-band pegs on the weight stack itself. And the G6 has band peg holes directly beneath each weight stack, making it relatively easy to loop a band over each stack.

It is still possible to add band resistance to the G15 weight stack, but it’s not exactly easy. See the photo below for the only way to do it — as you can imagine, it’s a bit of an involved process:

Force USA G15 All-In-One Trainer - Hack to Add Band Resistance to the Weight Stacks

Who Is the Force USA G15 Best for?

The Force USA G15 is well suited for these scenarios:

  • Bodybuilders: The G15 is a top choice for bodybuilders due to its selectorized weight stack system, which allows for instant weight changes, and easy drop sets and super sets. The small 2.5 lb increments made possible by the 4:1 ratio are incredibly useful for progressing on isolation exercises such as lateral raises.
  • Personal training/physical therapy studios: The G15 is ideal for personal training studios and physical therapy practices due to its selectorized weight stacks for easy resistance adjustments, interchangeable 2:1 and 4:1 pulley ratio for versatility in training clients of varying strength levels, and counterbalanced Smith machine with a starting weight of 0 lbs for novice or rehab clients.
  • Family use: The G15 is a versatile option for families or couples who plan to share its use. This usually means there’s a range of strength levels among users. The strong/experienced lifters will be able to achieve heavier resistance with the 2:1 ratio. The weak/novice lifters will be able to use small enough increments with the 4:1 ratio.
  • Gyms with low ceilings: The G15, like the G10, is a great option if you’re looking for a premium all-in-one gym that will fit in room with short ceilings. The unit is 7’3″ (87″) at its highest point and only 7’8″ (92″) of space is required for most people to do pull ups without hitting their head.

Force USA G20 Pros

Selectorized Weight Stacks

The Force USA G20 is the top-of-the-line G-Series model. So as you’d expect, it uses a selectorized weight stack system. The ability to rapidly adjust resistance saves valuable time and energy during your workouts compared to a plate-loaded setup.

Force USA G20 Selectorized Weight Stacks

Each selectorized weight stack weighs a whopping 289. Even with a 2:1 ratio, this provides 144.5 lbs of resistance, which is enough for most lifters. But if that’s not enough, I’ll explain how you can access a 1:1 ratio in the section below:

2:1 and 1:1 Pulley Ratio

The Force USA G20 has the potential to have the best of both worlds when it comes to pulley ratios: Access to both a 2:1 and 1:1 pulley ratio. Let me explain…

The functional trainer on the G20 base unit has a 2:1 pulley ratio (i.e. selecting 100 lbs provides 50 lbs of resistance). This gives you the benefit of a smaller 5 lb weight increment for each weight setting, which makes it easier to progress on lighter exercises. The downside is that max possible resistance is half of the actual weight stack’s weight.

Force USA G20 Functional Trainer Weight Stacks

That’s where the optional Lat Row Station Upgrade comes in clutch. It gives you a third 289 lb weight stack for the back of the unit that uses a 1:1 ratio. It’s designed to be used for lat pulldowns and low rows, which are the two main cable exercises that require heavier weights.

Force USA G20 Optional Lat Row Station Upgrade

Most Robust Model

The G20 has the beefiest build of all the G-Series units. It features thick 11-gauge uprights while several models (i.e. the G3, G6, G9 and G12) use thinner 12-gauge steel. Additionally, the G20 has a larger frame overall than all other models. It features a bigger rear crossmember as well as stabilizing steel strip that bridges between the feet of the rack.

1″ Hole Spacing

Force USA G20 Power Rack - Uniform 1 Inch Hole Spacing

Traditional Westside spacing gives you precise 1” hole spacing in the bench zone and 2″ spacing above and/or below that. Well, the G20 goes beyond that by having uniform 1″ hole spacing throughout the entire height of the uprights.

This is as precise as you can get. You’ll be able to position your j-hooks, spotter arms or other attachments exactly where you need them. This is great for any lifter, but powerlifters in particular will appreciate it the most since having the j-hooks exactly where you want them can sometimes make the difference between hitting a new PR or not.

Walkthrough Design

The G20 base unit has a super convenient walkthrough design. You can go through it from the back or the front. This is great when you’re moving plates around or switching between exercise stations.

None of the other G-Series units have this design.

Note, however, if you do buy the optional Lat Row Station Upgrade that you will lose the walkthrough design since the Lat Row Station attaches to the back of the frame.

Tallest Model

The G20 is the tallest G-Series model in terms of both its external height (91″) and internal height (84″). This makes it a top choice for taller lifters. They will have plenty of clearance when working inside the machine (e.g. Smith machine and some cable movements). Plus, they’ll be able to set the j-hooks high enough for squats when working outside of the unit.

Importantly, being on the taller side also means that most lifters will be able to get a full stretch on lat pulldowns while seated on a bench. In order to do that on the shorter G-Series models, you have to be seated on the floor.

Band Peg Holes

Force USA G20 - Band Peg on Smith Machine

The G20 features band peg holes on the flat feet of the rack. It comes with 4 band pegs that you can insert into any of these holes.

This allows you to easily add band resistance to your barbell or Smith machine exercises like squats, deadlifts and bench press. You can even add band resistance to some bodyweight movements like hip thrusts and pull ups.

Integrated Weight Stack Band Pegs

Force USA G20 Functional Trainer Weight Stacks with Integrated Band Pegs

With the G6 and the G3, you could add band resistance to the weight stack using the band pegs on the feet of the rack. While effective, it’s not a seamless process.

The G20 makes this process super easy by having built-in mini band pegs on the top and bottom of the weight stack itself (on both sides). So you simply loop the band around these mini pegs and you’re ready to lift.

Of course, most people won’t need to add band resistance to go beyond the 289 lb max of each weight stack — though that is possible to do. Rather, the most practical use is to add band resistance to achieve a different training effect; to make the resistance heavier at the top of the range of motion.

Roller J-hooks

Force USA G20 Roller J-hooks on Power Rack

The G20 is the only model with roller j-hooks. Roller j-hooks allow you to effortlessly move a loaded barbell to the left or right, in order to center on the j-hooks before lifting off

Multiple Chin Up Bars

Force USA G20 All-In-One Trainer - Exercise Stations

All other G-Series units have a single chin up station. The G20 has 2 chin up stations. One is a regular multi-grip chin up station like on the other G-Series models. The second station is a globe-grip style/multi-grip chin up bar.

Not only does this allow you to do different types of pull ups (i.e. grip-focused or regular), but it also allows you and a trainer partner to do pull ups at the same time.

Bolt-down

You have the option to bolt the G20 to the floor, unlike on G9, G10, G12 and G15. That said, the vast majority of owners will have no reason to bolt it down. The base unit alone weighs 1510 lbs. It’s not going to budge.

Force USA G20 Cons

High Price Tag

It’s no secret that this is an expensive machine. The base unit is $5,999 and the optional upgrade station is another $1,299. On top of that, there is also an optional upgrade kit available for another $499.

Of course, a high price tag comes with the territory when you’re talking about such a heavy, feature-rich all-in-one gym. If it’s too expensive for your budget, you should consider saving up your money before you buy or opt for one of the less expensive models. Also, consider the available financing options (i.e. Affirm).

Smith Machine Isn’t Counterbalanced

Unlike the G9 and G12, the G20 does not have a counterbalanced Smith machine. That is, the bar weighs 45 lbs when it’s empty, instead of 0 lbs.

This is not a big deal for most people, since they’ll be able to lift more than the empty bar weight for any Smith machine exercise. However, if anyone using this machine is very weak and/or a complete novice, the empty bar may be too heavy.

Who Is the Force USA G20 Best for?

There are a bunch of different applications where the Force USA G20 is a good choice:

  • Home gym owners seeking the highest quality and most feature-rich all-in-one gym: If you’re a home gym owner who simply wants the best all-in-one gym, this is it. It’s got all the bells and whistles. You just have to be willing and able to pay the premium to get it.
  • Serious bodybuilders and strength trainees: This is the best unit if you’re serious about lifting heavy. Bodybuilders and powerlifters alike. The fact that it has selectorized weight stacks in the first place is a win for bodybuilders, who need that to do drop sets and supersets on cable work. Then you have the fact that the weight stacks are heavy at 289 lbs (with the ability to easily add band resistance). This is good for strong bodybuilders and powerlifters alike. And powerlifters in particular will be big fans of the power rack having uniform 1″ hole spacing for precise j-hook placement.
  • Lifters who want both 2:1 and 1:1 ratios: The new G20 design introduced 2:1 ratio weight stacks to the functional trainer (in place of the 1:1 stacks on the original design). This helped solve the complaint of the starting weight and the increments being too heavy on certain exercises for some lifters. However, you can still reap the major benefits of a 1:1 ratio by opting for the G20 Lat Row Station Upgrade, which is designed specifically for the cable exercises that require the most weight: lat pulldowns and low rows.
  • Personal training studios or physical therapy practices: The G20 can make the perfect centerpiece in your studio for resistance training. It’s the sturdiest of all the G-Series models, which will help it withstand daily use from multiple clients. It has weight stacks, which are a must when training clients since the near-instant weight change process will save you valuable time and energy. The only downside is that the Smith machine isn’t counterbalanced, which may be an issue for certain clients.

  1. Hi Alex,

    This is a good review of the different units. I have one question and one comment:
    First, I think you might have the price for the G6 mixed up with the price for the G9. ForceUSA lists the G6 as $3999.
    My question is whether you know if the MyRack attachments like the lat seat work with the G3.

    Reply
    • D’oh! You’re right, I accidentally swapped the prices in the table. Just updated it — thanks for catching that.

      No, the MyRack attachments don’t work on the G3, since the upright tubes are different sizes (2″x2″ on the G3 vs 2.4″x2.4″ on the MyRack). The only MyRack items that work on the G3 are the band pegs and the landmine attachment (if you wanted to install a second landmine attachment in the back of the G3, instead of using the G3 landmine that comes standard and is fixed on the front of the G3.)

      Reply
  2. Oh one more question Alex…. Do you know if that stability attachment is long enough to use for lat pull downs if I am seated on a bench?

    Reply
    • Great question. Yes, the stability attachment is long enough to use lock your legs down for lat pulldowns if you’re sitting on the bench. This was one of my favorite “hidden” features of the stability attachment. It can basically replace the need to get the lat pulldown seat (assuming you’re okay with doing lat pulldowns in the center of the rack with the long bar or both stirrup handles, instead of on one of the pulley columns).

      Let me know if you have any more questions.

  3. Really want to get the G9/G12, but the max bar height of 60 inches in the power rack is tough. I’m only 5’9”, and that’s right where I like my bar set for squats. I workout with guys that are 6’1” and 6’4” – just want to confirm this limitation

    Reply
    • Hi Shane. Yes, the max height is 60″ (i.e. 5 ft 0 in) — that’s the distance from the floor to the bottom of the barbell shaft. I’m 5’11” and I tested that height in my power rack just now and it’s even a little too high for me, as the bar scrapes the top (note that I’m a high bar squatter, too). My ideal height for unracking (again, using a high bar position) is actually 57″-58″ (i.e. 4 ft 9 in – 4 ft 10 in), so I’m quite confident both you and the 6’1″ guy would have no issues at all…

      …The 6’4″ guy will likely have to bend his knees more — though a lot of it depends on his bar position on his back, and to a lesser extend his squat stance width. A low bar position and a wider stance will mean he’ll have to bend his knees much less to unrack than if he uses a high bar position with a narrow width stance.

      What I’m going to do is reach out to my contact at Force USA. I’ll see if he can take a photo of someone on their team who’s around 6’4″ unracking the bar when the j-hooks are at in the highest accessible hole. So stay tuned for that.

        • Hi Shane, I was in contact with Force USA and I asked them about the viability of a workaround for tall lifters on the G9/G12, which I had in mind previously but wanted to confirm before mentioning it. Let me explain the concept, and then tell you the caveats, and pros/cons of doing it…

          …And that is, you can technically install the j-hooks above the pulley in order to install the j-hooks in either of the top 2 j-hook holes that would otherwise be inaccessible. If you do this, you get a rackable bar height of 63.75″ above the floor and 67″ above the floor.

          So, how do you do this workaround? You lower both pulleys down to a lower setting. Then you move the pulley cable to the outside just enough to install the j-hooks in either of the top 2 holes. There is enough slack in the cable to move the cable to the outside — and there’s also enough slack that the cable will push back along with the barbell when you rack the bar after a set.

          Below, I’ve included a video the guys at Force USA filming a 6’4″ lifter using the workaround. He has the j-hooks in the second highest hole (bar 63.75″ above the floor). You’ll notice that even in this higher position, he has some trouble getting it cleanly over j-hooks even with the empty bar. He would’ve actually been better off using the 3rd hole from the top hole (bar 60″ above the floor), which doesn’t require the using the workaround at all! — As such, it’s more accurate to say that this workaround may only be helpful for lifters over 6’5″:

          Here’s a closeup shot of the bar being racked when using this workaround. Note there’s enough slack to allow the bar to go to the back of the j-hooks:
          Workaround for Extra Tall Lifters Squatting in the Monster G9 and G12

          NOTE: Although this workaround will work, it’s officially not recommended because it can wear the cable sheath down over time, particularly if your bar has very sharp knurling. So, it is NOT something to rely on regularly (i.e. if you’re the very tall lifter using it all the time). But you can probably get away with it if done sparingly (e.g. if you have a tall workout friend who uses it only once in a while — even then, you could put some athletic tape around the cable bar for protection when the bar makes contact to minimize/eliminate any friction damage).

          Reply
  4. Hi Alex,

    Well…I wanted to let you know that I bought the Monster G9 and was super excited when I received it 2 days ago. Unfortunately I have had a pretty bad experience so far.

    The unit I received doesn’t look entirely like the one pictured on their purchasing site. It is branded all over with the name G9, but the exercise chart is totally different and the chin-up bar is the arched ladder type and not the two part version with the pronated grips shown in the website. I actually am pretty upset about that because I specifically wanted the pronated grips and the bar they sent me is way too tall for me. I’m only 5’6″, but when I installed the chin-up bar they had in the box I could barely touch it even while standing on a 2-step stool. That’s practically unusable for me.

    There were also bunch of typographical errors in both the manual they sent me in the box as well as the downloadable version. The manuals both have a picture of the G9 on the front page, but if you look closely, they don’t even look the same as each other. The downloadable version looks like what I expected I was buying. The manual and the unit I received do not, even though the machine and the manual both say G9 on them.

    Finally I have had at least 2 broken parts right out of the box:

    * A spacer insert for the functional trainer pulley was broken in two places
    and is preventing the pulley from smoothly sliding up and down the rail.
    * One of the slider sleeves on the Smith Machine actually had bearings falling
    out of it as soon as I took it out of the bubble wrap it was packed in.

    I basically gave up trying to assemble the unit. Due to the differences in the G9 I received compared to the one they advertise on their website, I am wondering whether I received a discontinued early version of the G9, or perhaps they just have poor quality control at the assembly plant. Due to the broken parts I am seriously concerned about even using the thing to work out with whether or not they send me replacements. This was supposed to be commercial grade, but I feel like the build quality is inconsistent with some parts seeming sturdy and others that appeared to made out of the cheapest material they could get away with. Several bolt holes were occluded with metal. I had to file two of them down just to get the bolt through the hole.

    Anyways, I am sorry to vent on your website, but partly I wanted to see if you could suggest a course of action. I have contacted their sales rep, who seemed very nice the first time I talked to him…however he hasn’t yet seen all the e-mails I just sent as I came upon multiple other issues. You did a really good job reviewing the products, but I wonder now if you actually own any of these and if you encountered any similar problems or have heard of any from other readers.

    I was reluctant to leave a review on their website for fear that it might jeopardize any potential refund or replacement of the product. I’m really concerned that a replacement would be no better to be honest.

    • Sorry to hear about that Brian! It definitely sounds like some kind of mix up, especially with the totally different chin up bar option.

      As I mentioned in the beginning of the review, I don’t own these myself. But rather, I visited their HQ so I could thoroughly test out each unit (I don’t have enough room in my gym to have one of these with my existing equipment). So, I didn’t have to go through the installation process like you did.

      I’m going to reach out to them to see if I can get any information about these issues to see what’s up. From all my interactions with these guys, I’m confident they’ll make things right. Stay tuned for more.

      • Hi Alex,

        Just wanted to leave a quick update on my G9 purchase. Cameron (the nice rep that I talked to previously) did contact me and has sent me some replacement parts which should arrive in a few days. He told me that all units are inspected before they leave the warehouse, and so damage may have occurred during shipping. As for the differences in the machine that was on the website vs the one I received he told me that ForceUSA made a few changes about a month ago (including the exercise guide/storage area and the chin-up bar). They apparently haven’t updated the purchasing page yet. They are still supplying the old style bar and he said they would send me one as soon as it is back in stock. Their customer service has been pretty good so far, so I really hope that I don’t run into any more issues during assembly. I’ll let you know how the final product turns out once I receive the replacement parts.

  5. Hi Alex,

    Could you tell me the height of the pull-up bar on the G12?
    I have limited ceiling height and would like to know if I could perform pull-ups correctly with this machine.
    If total height is 228cm, I guess the pull-up bar might be somewhere between 215-218cm.

    Thanks a lot for your review.

    • Currently and for a limited time, ForceUSA.com is selling the G12 (and G9) with a slightly different chin up bar than the one shown in my images. It is more of a Monkey style chin up bar, and is taller at 90 inches above the floor. That said, in a few weeks, they’ll be reverting back to the original chin up bar shown in my photos, which is 87 inches above the floor…

      …And you can actually request this 87 inch chin up attachment now if you reach out to them.

  6. Hi Alex,

    Many thanks for your reviews
    It is quite helpful.

    Do you recommend G9 as the best functional trainer for home use or are there any other brands which are better and cheaper in comparison?

    Thanks

    • The Monster G-Series (including the G3, G6, G9 and G12) are the best group of all-in-one gyms on the market, in my opinion. However, it’s hard to give a definitive answer to which one of those four models is “best.” This is because they all have different features that will appeal to different types of lifters.

      Personally, I think the G9 is the best value (bang for your buck) model. You can read my full Monster G9 review here.

  7. hola Alex,

    la barra de dominadas del modelo G3 ( no me ha quedado muy claro si al final la del modelo G9 es igual) se podría colocar al revés si tengo problema de altura en la habitacion?

    Reply
    • Hi Javi. I believe you asked if you can flip the G3 pull up bar upside down if you have a ceiling height problem? If that’s what you asked, then the answer is no — Unfortunately, you can’t do that because there is a lip on top of the G3 multi-grip bar that makes it only fit one way. However, you can get the optional G3 Straight Chin-up Bars instead. This will give you more clearance for your head when doing pull ups on the G3.

      If you’re asking about the Monster G9, it currently ships with a pull up bar that’s similar to the G3 style pull up bar. It also cannot be installed upside down. The G9 unit is 90″ tall with this pull up bar installed. However, you can request the original pull up bar (i.e. shown in the photos on this page; with the multi-grip peg style handles), which makes the unit height 88″ tall.

  8. Hi Alex,

    Just received my G12.
    But was disappointed to see that they send chin up bar from older model.
    The dealer mentioned he would replace with new chin up bar in next 1-2 months due to COVID 19

    Could you please let me know if chin up bar was the only difference in the new model?
    Should I check anything else?

    Thanks and Regards,
    Sri

      I shared your comment with my contact at Force USA. He actually said that they do have some of those chin up bars in stock now, and that they should be able to get you one sooner. I gave him your details so they can look up your order and then get you taken care of with the chin up bar.

      As for your main question — No, there aren’t any other changes to the G12. I confirmed this with Force USA.

  9. bonjour,je compte vendre mon monster Barbarian qui est le G6 pour le G12.cependant il y a un probleme avec la longueur des cable du poulie vis a vis.en effet lors des elevations laterals il faut rester proche des montants au rique d entendre les plaques de poids frappées en fin de course.pouvez vous me dire si le probleme va etre résolu?
    merci beaucoup

    Reply
    • Hi Guy, the G12 cable extends a max of 53″ out of the pulley. Whereas, the G6 extends 51.5″, so you get a little more length with the G12.

      I’ll note that when I was using both units, I didn’t have any issues with maxing out the length of the cable with any of the movements I tried. Maybe the issue is with setting the pulley at the right height. I’d have to know more about your situation (e.g. which exercise did you have an issue with the pulley length on the G6?).

  10. Salut merci pour la réponse,je n ai justement aucun problème avec la longueur du G6,juste la démultiplication 1.2 qui m oblige a mettre des élastique au dessus de la pile de poids et surtout le Smith machine qui est trop étroit et l on touche parfois les cotés avec les coudes lors de l exécution de développé couché par exemple.Pour le G12 sur youtube on voit des gens touché très rapidement aux élévations latéral le haut de la machine d ou ma question.

    Reply
  11. Have the G3, wouldn’t recommend for tall people as the pulleys sit to low so can’t get full extension with lat pull downs.

    Reply
    • The workaround there might be to do them from the floor, or set the seat extra low (though you may not be able to bend your knee in that case. Otherwise, the G6 will be a bit better for that particular exercise.

  12. Hey Alex
    Loved reading your reviews for the g series so indepth
    Just wondering if you’ve reviewed or had a chance to use the f50 and what the main differences from the g series are apart from stacks and leg press ect
    Thanks

    Reply
    • Hi James, thanks! I put a lot of time and effort into the G-Series reviews, so I’m glad you liked them 😀

      I haven’t done an F50 or F100 review. However, I have tested both, although only very briefly. Still, I can tell you the main differences aside from the stacks and leg press:

      • The uprights are much further apart on the F50/F100. They’re so far apart that it requires a special barbell (which comes included). This special bar has a longer shaft so the sleeve collars are 53″ apart, allowing it to actually fit on the . This barbell does the trick for the basics but will leave you underwhelmed if you’re a barbell geek and it will feel a bit different because of the long shaft. You won’t be able to use regular barbells in this power rack. (NOTE: The G9 and G12 are relatively wide, still narrower than the F-Series I believe, but their safeties and j-hooks are indented in making them effectively closer together for barbell exercises.). Note that while extra wide uprights is a drawback for power rack/barbell purpose, it’s a plus for bilateral functional trainer exercises like chest flies and cable crossovers because it gives you a bigger stretch.
      • The steel gauge for the frame is noticeably thinner on the F50/F100. I believe it’s 14 gauge, compared to 12 gauge on most of the G-Series (11 gauge on the G20). That said, it’s still strong enough for most lifters.
      • It has a nicer footplate option for low rows. It’s designed specifically for it. On the G-Series, the best foot plate option is using the leg holder pad, which actually works pretty good, but it’s still a pad and not a plate.
      • There’s no vertical barbell holder.
      • Despite not being as premium of an offering as the G-Series models, the smoothness of the F50/F100 cable systems is very good. It’s on par with the G-Series (probably actually a bit smoother than the G3).

      Lastly, I’d just ask — Are you in the US? Because I don’t believe they’re selling the F-Series in the US anymore, and I’m not sure if/when they’re coming back. But if you’re in Australia, UK or other regions, I do think they’re still being sold there.

      • Thanks for the quick reply
        Going by that and your reviews think ill save the extra dollars and go for the G6
        Im in Australia so the F50 is alot cheaper
        Hoping force usa release some jammer arms in the future to add but aint no biggie if they dont
        Thanks

  13. Hi Alex,
    Looking to purchase either G6/G12/G15 here in Canada.

    I have pointed out to ForceUSA Canada customer support that their pricing in Canada does not make sense compared to US pricing given the current Can/US Conversion. For instance it is CHEAPER to purchase the G12 and G15 in Canada than it is in the US, but much more expensive to purchase the G6 in Canada than it is in US. These questions/ comments I have posed to ForceUSA customer support have unfortunately fallen on deaf ears.

    I am looking for your opinion on which unit you would purchase (G6/G12/G15) for a home gym to be used by a male and female couple (intermediate lifters). The G6 seems like the best deal considering all included attachments and the 2:1 ratio is appealing. If the G15 came with the leg press standard it would be a no-brainer for the extra $1000 over the G6 here in Canada.

    Thanks in advance!!

    Reply
    • I looked at the ForceUSA.ca (Canada) website and I think I’m following what you’re saying regarding the relative price differences between US and Canada.

      Putting that aside, even though the G6 is relatively more expensive compared to the US’s G6 price, it is still the least expensive option among the G6/G12/G15 in Canada…

      Overall, I agree with you in that the G6 is the best deal for your needs. One reason, like I mentioned right above, is that it’s the least expensive of these 3 models in Canada.

      But that’s not the only reason. I’d eliminate the G12 from your consideration since it’s a 1:1 ratio, and that’s probably the biggest complaint of male/female couples who both train on the unit…that the increments are too large (of course you could buy slim magnetic adder weights to put on the stack, but that makes the flow of your workout less efficient…I’d recommend this workaround if you REALLY wanted a heavier max resistance from the G12’s 1:1 ratio). Additionally, in terms of G6 vs G12, the G12 is much more shallow internally so you don’t have enough room to do incline Smith machine press variations; whereas the G6 has plenty of room for that.

      In terms of the G6 vs G15, I’m not sure if the significantly higher price of G15 (especially when you consider the extra price of the G15 upgrade kit) is worth it compared to the lower cost of the G6, which comes with everything included. You do miss out on the tighter hole spacing that G15 provides, but I wouldn’t call that a dealbreaker for most people. You also don’t get the interchangeable 4:1 and 2:1 pulley ratio that the G15 has, but considering your wife/girlfriend is an intermediate, she should be fine with the increments of a 2:1 system. The only strong reason in my opinion to opt for the G15 over the G6 would be if you REALLY want the jammer arms that come in the optional upgrade kit. But since you didn’t mention anything about those in your comment, I’m guessing they’re not a must-have.

      So to reiterate, yes, I think the G6 makes most sense for you given what I can surmise from your comment of your needs/wants and it seeming you do have at least some budget concerns.

      Hope this helps!

      • Hi Alex,

        Thank you so much for the detailed response to my questions!!

        Thank you also for taking the time to look into my pricing discrepancy comment as well, although I wish Force USA would’ve commented further when I brought this up to them instead of brushing me off.

        The quick math and price discrepancy looks like this:
        – G6: $3999 USD (American site) —> (x1.31 usd:can conversion) = $5240CDN. ForceUSA Canadian site selling for $6000CDN. This is $760CDN or $580USD more than American site)

        – G15: $5499 USD (American site) —> x1.31 conversion = $7205CDN. Canadian site selling for $7000CDN ($205CDN cheaper than American site)

        – X15: $3999USD (American site) —> x1.31 conversion = $5240CDN. Canadian site selling for $6500CDN ($1260CDN more on CDN site than American site).

        Based on you recommendation I will proceed with getting the G6 and be sure to use your discount code.

        Could you explain how I would use both weight stacks to lat pull down and how to anchor my legs if using both and centred on the machine? Do you have a video of this in one of your reviews?

        Thanks again for all your help!

        Reply
        • You bet! So, in terms using both weight stacks for lat pulldowns and anchoring your legs, there’s a few ways to go about this.

          Let me first go over the different strategies for using both weight stacks in the center of the rack:

          • You can use the stirrups/d-handles, which allow you do lat pulldowns unilaterally or bilaterally.
          • You can attach the long straight bar, which connects to both pulleys at the same time. This bar is on the thicker side, so you’d probably want to use lifting straps for a better grip. Also, it’s not the best bar if you’re using a wider grip for lat pulldowns, since the bar is straight and that can be a bit uncomfortable on your wrists. But it’s still solid for a more medium grip or a close underhand grip.
          • You can attach extension chains with carabiner clips on each pulley to connect to the included lat pulldown bar so that you can use it in the center — if that makes sense. Since the unit only comes with 2 extension chains and I don’t think they’re long enough to reach from the pulley to the center of the rack, you may need to buy a couple of chains from your local hardware store, so you can daisey chain them together. While this is a bit more of a complex setup, it’s probably the best because you get to use an actual lat pulldown bar.

          Regarding anchoring your legs while doing pulldowns in the center of the machine, here’s my suggestion:

          • Use your weight bench to sit on. Attach the spotter arms at about the height of the weight bench surface. Use a thick enough resistance band to stretch across both spotter arms. You can use the band pegs in the spotter arm holes to makes to make this easier. Then sit down on the bench and put your legs under the band. If the band is thick enough, this will keep you planted.

          Now you may already know this from reading my G6 in-depth review, but you also have the option to do lat pulldowns on just one side of the machine using a single weight stack, BUT going beyond the max resistance of the weight stack. There’s two options for this:

          • Using band resistance by attaching resistance bands to the band pegs inserted into the hole under the weight stack, and then looping the band over the top of the weight stack.
          • Buying a GymPin or BSE Stacked Weight Pin. These allow you to add Olympic weight plates to the weight stack. With the G6, you don’t have room for fit full diameter plates (i.e. 45 plates), but you can fit smaller diameter plates, including 35 lb plates and smaller, which still lets you add a lot of extra weight.

  14. To date, when it comes to service I have not been impressed. I have been unable to reach by phone, and email/chat is less than adequate. It sure would be nice if Force USA would a la carte their accessory items. It would also be nice if they would let you buy a trainer and hold it until it can be completely shipped with backorder accessories so that you only have to put your trainer together once, as in the G6. This would allow the consumer to get the full use of the equipment for the 30-day trial to ensure satisfaction. I see that there are a lot of satisfied customers, but for such an expensive purchase and the inability to reach anybody on the phone gives me concern.

    Reply
    • Hi Curt, so sorry to hear about that. Those are all good suggestions re: the backorder idea. I gave my contact at Force USA a heads up about your comment regarding your issue getting in contact with them over phone, so hopefully that helps out. Usually their customer service is great, but things can inevitably fall through the cracks at any company. Fingers crossed you and them can get this particular issue sorted.

  15. Hi Alex,

    Thanks for the review and description. We’re looking at G6 or G15 for family use (all adults and intermediate users). If the G6 and the G15 were at the same price (including all the upgrades for both), which one would you recommend?
    Thank you.

    Reply
    • Hi Rams, thanks for the question. It’s a tough choice, but if we do assume the same price with all upgrades, I’d go with the G15 over the G6. My particular reasoning is that the G15 has a few notable features that the G6 lacks — namely, closer hole spacing, slightly better build quality, angle options on the leg press, and the option for 2:1 AND 4:1 ratio. The main downside compared to the G6 is that it’s a bit shorter, but I think the other factors outweigh that.

      Of course, in practice, the G6 costs notably less than the G15, so it’s probably a better choice strictly in terms of bang for your buck. But I get the sense you’re just trying to figure out which is better overall, and that’d be the G15.
