Force USA Monster G12 Review - All-In-One Gym

This is the most in-depth Force USA Monster G12 review you’ll find anywhere online on this piece of gym equipment.

The Monster G12 is the most premium model available in Force USA’s series of all-in-one gyms. What makes the Monster G12 the highest end model? A lot of things. But its two primary differentiating features are that:

  • It has a commercial warranty rather than a home use warranty thanks to its extra wide, reinforced frame; AND
  • It has a selectorized weight stack pulley system as opposed to a plate-loaded system (both stacks have a 1:1 pulley ratio and provide up to 201 lbs of resistance each)

Read on to find out about ALL of its features, specs, attachments, pros and cons. By the end of this Monster G12 review, you’ll know if this machine is the best all-in-one gym for you.

Force USA Monster G12 Features

Space-Efficient Design

The Force USA Monster G12 is very compact when you consider all of the exercise stations contained in its design. It packs 8 different training stations into about a third of the footprint you’d need if you instead bought dedicated equipment for each station.

Being compact while delivering tons of features is a design priority for an all-in-one gym like the Monster G12. The Monster G12 actually has the smallest external depth footprint of all the G-Series, at 49″ (vs 55” for the G3; 63” for the G6; 53” for the G9).

External depth is probably the most important footprint dimension for space efficiency. External width isn’t as important, since you’ll need a little over 7 feet of width anyway to use a barbell and the Smith machine, regardless of which model you buy.

On top of the smaller depth footprint, the Monster G12 is the only model you can position flush against a wall. Whereas, the other models all require at least a few inches of clearance to fit the weights on the plate storage area, or on the plate-loaded weight bracket in the case of the G9. This makes the Monster G12 even more compact in practice compared to others.

Monster G12 All-In-One Gym Can Be Positioned Flush Against a Wall
Note how the back of the machine could go right against a wall. There are no long feet in the rear, and the plates are angled to the front, out of the way.

The G12’s space-efficient design is perfect for anyone with limited space who does NOT want to compromise on exercise selection. This includes:

  • Home gym lifters with only a small room in their house, or with limited space in their garage or basement.
  • Certain commercial settings, such as personal training studios, physical therapy offices and many other places that I’ll cover below. The G12 is one of the two Monster all-in-one models designed specifically for this type of commercial use.

In a lifter’s utopia, everyone would have dedicated gym equipment instead of an all-in-one gym. You obviously get more out of dedicated equipment since it’s designed for a single purpose. Whereas, equipment companies sometimes need to make slight design compromises on all-in-one exercise stations to ensure all components fit together and function properly…

…For example, a dedicated power rack has a deeper space to squat inside, with uprights protecting you in both the front and back. In comparison, the G12’s power rack uses just the uprights in the front. Similarly, it’s easier to get into a reclined seated position on a dedicated 45 degree leg press machine compared to laying flat on the G12’s vertical leg press; plus, you can load on more weight.

However, we don’t live in a utopia. As such, there’s plenty of reasons why buying separate equipment doesn’t make sense for a lot of people. Limited space, budget and convenience are the big ones — You get these 3 major benefits as a trade-off when you get an all-in-one like the Monster G12 instead of dedicated equipment.

You still get the most important benefits and capabilities of specialized equipment. You lose out on the marginal benefits. But you also get a more space-efficient, budget friendly and convenient solution.

Cost Saving Design

Yes, the Monster G12 is the most expensive G-Series model. Yet it will still save you hundreds if not thousands of dollars compared to buying separate pieces of comparable quality equipment that replicates the G12’s functionality.

Monster G12 All-In-One Gym Saves Money Compared to Dedicated Equipment

With a price tag of $4999 — before the 5% discount from using code KING5 — the G12 will be out of some peoples’ budgets. However, when you pay more, you get more. Even at the higher price, you still get a lot of value out of the G12 for what you pay.

The most expensive part to manufacture on the Monster G12 is also its most attractive feature: the two 201 lb selectorized weight stacks.

Changing weight on these weight stacks is orders of magnitude faster than it is on the plate-loaded G9 and G3 units. And they have almost twice as much resistance as the G6’s selectorized weight stacks (201 lbs vs 110.5 lbs per stack). No other unit lets you train as efficiently and with as much resistance.

If you have the budget for it, then I’d definitely recommend choosing the G12 to get its weight stacks — You’ll love how efficient it is and you’ll enjoy its convenience every single workout.

However, if you’re on a tighter budget, the G9 will get you every other feature that the G12 has but for $1800 less. Or, you could pay $1000 less and still get a selectorized weight stack system by opting for the G6 if you’re okay with less resistance.

Versatile Design

The Force USA Monster G12 is built for versatility. That is the point of an all-in-one gym, after all.

Monster G12 All-In-One Gym Versatility

It has a total of 8 exercise stations that let you do some version of nearly every movement you could do in a fully outfitted commercial facility.

The only feature it lacks that detracts from its versatility is band peg holes. So you can’t do band-resisted exercises like you can on the G6 and G3. Though, there is a DIY workaround to this, which I’ll explain later.

Here’s a breakdown of the hundreds of exercises that are possible on the Force USA Monster G12 all-in-one gym:

  • The power rack gives you access to 40+ free weight barbell exercises including variations of the squat, bench press, overhead press and many other movements.
  • The exercise station that puts the biggest dent in exercise selection is the functional trainer. It allows you to do an impressive 75+ cable exercises. The secret to its versatility is that you can use any hand position at any pulley height using any number of accessories — allowing you to hit any angle through an unrestricted range of motion.
  • You can do a Smith machine variation of most power rack barbell movements. There’s also some movements you can do only in the Smith machine. In total, you have an easy 30+ Smith machine exercises at your disposal.
  • You can do 30+ exercises on the landmine / core trainer. One of the most powerful movements is the T-bar row, but there’s also several core-focused movements and many landmine variations of traditional lifts (e.g. squats, deadlifts, press).
  • You can do 9 basic chin up variations based solely on the various ways you can grip the handles. You can do several more chin up variations if you get creative (e.g. static holds, explosive/clapping, side-to-side, weighted, band assisted).
  • The dip station has 2 pairs of handles that let you do 2 basic dip variations (wide and narrow grip). Other dip variations are possible if you think outside the box (e.g. side-to-side, weighted, band-assisted) as well as some non-dip exercises like inverted rows and inverted shrugs.
  • The suspension trainer ring is the perfect place to install your own TRX (or other brand) to take advantage of 80 suspension trainer exercises. A cool “off-label” use involves looping a band through the ring so you can do resistance band exercises (e.g. triceps extensions, face pulls, assisted chin ups and others).
  • The vertical leg press attachment is a powerful leg training tool that lets you do 3 leg press variations: narrow, shoulder width and wide stance leg press.

Later on in this Force USA Monster G12 review, I’ll give you many more exercise examples when I talk about each exercise station in-depth.

Commercial Quality & Warranty

The G12 is built and warrantied for use in commercial settings. It has a stronger, wider and more durable frame than the residential units. This allows it to better stand up to the rigors of more demanding training environments.

While the G12 is warrantied for commercial use, it is not ideal for a high traffic big box gym setting. This is because it is an all-in-one gym, which doesn’t make sense in that type of environment because:

  • You could potentially have too many people waiting to use any one of the many stations.
  • Big box gyms will already have tons of dedicated training equipment, which makes an all-in-one machine redundant and thus unnecessary.

However, the Monster G12 is perfect for other types of commercial settings, including:

  • Small local gyms or community fitness centers with limited strength training equipment
  • Personal training studios
  • Physical therapy practices
  • Boxing/MMA gyms
  • Police department gyms
  • Fire station gyms
  • Military base gyms
  • Office gyms
  • Hotel gyms

The Monster G9 is also great for all of these commercial settings. However, the Monster G12 has an edge because each cable column can be used independently; meaning two people can do different cable exercises at the same time. You can only use one cable column at a time on the Monster G9.

Power Rack

Monster G12 Power Rack

The Force USA Monster G12 power rack is technically a “half rack” because it has just two columns in the front. It isn’t fully enclosed with another two columns in the back.

Nevertheless, you can do nearly all the same barbell exercises in a half rack as you can in a true power rack. And you get the benefit of taking up much less space in your gym area.

The Monster G12 power rack gives you access to 40+ barbell exercises. Here’s some of my favorite ones:

Note that some of the above movements require an adjustable weight bench, which is not included with the Monster G12.

The Monster G12 has a 992 lb weight capacity rating. This is the same as all the other Monster G-Series models. It’s more than strong enough for you unless you’re truly an elite squatter.

The Monster G12 has the same extra wide power rack frame as the Monster G9. It also shares the same exact j-hook and spotter arm designs. You can see just how wide the unit is in the video below — I’m using a super wide grip on bench press and I still have a lot of extra space on each side:

To be specific, the Monster G12 power rack has a 48″ internal width, which refers to the distance between the insides of the uprights. Its external width measures 52″ from the outside of one upright to the outside of the other. This beats out the width of the Monster G6 by 7″ and the Monster G3 by 4″.

Monster G12 Power Rack Uprights - Internal and External Width Measurements

One benefit of the wider frame is that you feel a deeper pec stretch at the top of the range of motion when doing cable flyes because your arms can open up even further. It’s closer to being like a dedicated cable crossover machine, which have the cable columns spaced several feet apart.

Another big benefit of the wider power rack uprights is that it makes the entire unit more stable since the base of the frame is wider.

The distance between the j-hooks and the safety spotter arms is actually less than the distance between the uprights. The j-hooks and spotters are both spaced 45″ apart (49″ from outside to outside). This is because they’re “indented” 1.5 inches to the inside of each upright.

Monster G12 Power Rack - Distance Between J-hooks

This indented design was made to ensure an Olympic bar could fit on the j-hooks and spotters. A regular Olympic barbell has a shaft that’s 51.5″ long. If the j-hooks/spotters weren’t indented, their outside to outside width would be 52″, which would mean the bar wouldn’t fit. By being indented, the outside to outside width is 49″, which leaves enough room to fit a 51.5″ bar shaft.

Spotter Arms

Monster G12 Spotter Arms

The Monster G12 power rack comes with a pair of safety spotter arms. The primary function of these is to catch the barbell at the bottom of the range of motion in case you fail on squat, bench press and other exercises.

It has a protective rubber insert along the entire length of the top surface. This will protect the bar from scratches and also absorb some of the impact when you set down or accidentally drop the weight.

The Monster G12 spotter arms are 15 inches long, just like the ones on the Monster G6 and Monster G9. If they were just a bit longer — like the G3’s 17.5” spotter arms — it would be perfect. I usually take a fairly large step back when walking the weight out since I’m used to squatting in a full power rack. If I do the same walkout on the G12, I end up with the bar just past the end of the spotters at the bottom of the range of motion…

…Of course, the solution to this is easy. You just have to do a shorter walkout. It may be slightly annoying at first because you’ll be closer to the uprights. But you’ll get used to it within a couples sessions.

J-hooks

Monster G12 J-hooks

The Monster G12 comes with a pair of j-hooks for racking and unracking the barbell on power rack exercises.

They’re the exact same pair of j-hooks as the ones used on the Monster G9. And they’re very similar to the Monster G6 j-hooks; except the G6 j-hooks have a redundant pop-pin security mechanism and are not indented to the inside of the uprights. Only the Monster G3 j-hooks are markedly different.

Monster G12 J-hooks with 4 Holes on Bottom for Leg Holder Attachment

The thing that stands out most when you look at the Monster G12 j-hooks is the series of 4 holes on the bottom of each one. These are used to make micro-adjustments to the height of the pads on the lat pulldown leg holder, which is another attachment that connects to the j-hooks. I’ll talk about the leg holder later on in its own section.

The j-hooks have a protective rubber insert just like the safety spotter arms. It lays across the top surface of the lower portion of each j-hook where you rack the bar. It helps prevent scratches or dings to the bar’s finish and knurling.

The G12 j-hooks have the same issues as the G6 and G9 j-hooks:

  • There’s no protective backing on the upper/rear portion. It will experience minor scratching scratching over time and so will your bar. Nothing major, but it could’ve been avoided.
  • There’s a bolt head sticking out of the upper/rear portion. This poses a risk for scratching or dinging your bar if you slam the bar directly into it.

Most people won’t care about minor cosmetic damage from these issues…

…However, if you’re like me and are obsessive about keeping your barbell(s) looking as new as possible, I’d recommend putting some type of protective covering over it. Here’s some easy DIY ideas if you want to do this:

  • You could buy some cheap foam tape to cover it. You’d need to reapply it every so often.
  • A longer term solution would be to buy some rubber bumpers (also cheap) to cover the bolt head. You might have to use a use a utility knife to carve out groove in the bumper to fit over the bolt head. This way, it would cover the bolt head and you’d be able to lay it flat against back of the j-hook. You could add a second bumper atop the first bumper for good measure if extra padding is required.

The G3 j-hooks are better than the G12/G9/G6 j-hooks because they have neither of these issues:

Monster G12 J-hook vs Monster G3 J-hook

While the Monster G12 j-hooks could be better, they do serve their basic function of being able to:

  • hold a heavy bar
  • remain secure when installed in the uprights

Hole Spacing & Hole Accessibility

The Monster G12 power rack has 16 holes on each upright. The holes are 1″ in diameter and are spaced 3.75″ apart center-on-center.

Monster G12 Power Rack Hole Spacing

A NOTE ON MAX HOLE HEIGHT / HOLE ACCESSIBILITY:

The top 2 j-hook holes on the power rack uprights are inaccessible…unless you use a workaround, which I’ll explain in a second. But first, let me explain why the two holes are inaccessible under normal circumstances:

Regardless of which hole you’re using, the cable pulley needs to be above the j-hooks (or spotter arms, or dip handles). This is because the cable runs directly in front of the power rack holes, extending from the pulley up to the top of the rack. So, the cable blocks you from installing any attachments above the pulley. Usually, you can solve this problem by simply moving the pulley to a higher setting…

…But when the pulley is at its highest possible setting, the pulley itself blocks the uppermost two j-hook holes.

Now, I mentioned that there’s a workaround. I’ll explain that now:

First, set the pulleys on a low height setting. Then, move each cable slightly to the side of its upright; just enough to install the j-hooks in one of the top two holes. There will be enough slack for the cable to run along the side of the j-hook. There’ll also enough slack for the cable to move back when you rack the barbell in the j-hook, as shown below:

Workaround for Extra Tall Lifters Squatting in the Monster G9 and G12

I should stress that Force USA does not recommend or advertise doing this, as it could cause the cable to wear down over time from the contact with barbell’s knurling (though, you could temper this by wrapping the cable with athletic tape around the area of contact for protection).

While this isn’t officially advised, my thinking is that you’d be okay if you only did this occasionally — For example, if you’re using the Monster G12 in a personal training or physical therapy setting, you could get away with doing it the few times you have a client squatting who’s taller than 6’5″.

Below is a video of one of the guys at Force USA demonstrating this workaround. Note that he’s 6’4″ and using a high bar position with no weights on the bar — even at his tall stature with the bar as high on his back as possible, he still has a little trouble getting the barbell cleanly over the j-hooks. This is why I say this workaround would only be useful for squatters who are over 6’5″.

The same issue exists on all of the G-Series racks except for the G6. And on the G3, just one hole is blocked.


The Monster G12’s 3.75″ power rack hole spacing is the same as on the Monster G9 and Monster G6. It does not have the narrower “Westside” hole spacing that many powerlifters have come to know and love.

If you’re unfamiliar, Westside spacing consists of ⅝” diameter holes spaced 1” apart in the bench press region and 2” apart everywhere else. This allows for extremely precise j-hook and spotter arm placement on all exercises, especially bench press.

You should consider the Monster G3 if Westside hole spacing is a must-have for you. It is the only Monster all-in-one gym model with this feature.

It would’ve been nice if the Monster G12 had Westside spacing as well. However, its 3.75″ hole spacing is still acceptable for most lifters. You’ll be able to set the j-hooks and spotter arms at the appropriate heights for safety and performance. You just won’t get the absolute “perfect” height on every single exercise.

I consider hole spacing less than 4″ to be adequate for most use cases. Even a little more than 4″ can be okay. But you’ll quickly run into issues the further you go above that. The first issue being performance loss from unnecessary range of motion during the unrack (e.g. unracking from a quarter-squat position). The second issue being a decrease in safety because you have to set the safeties much lower than the bottom of the range of motion to stop the bar in case of failure.

Functional Trainer

The functional trainer is the focal point of the Monster G12 all-in-one gym. It’s the single feature that delivers the greatest amount of versatility in terms of exercise selection.

Monster G12 Functional Trainer

The functional trainer consists of two pulleys, each on its own column. The pulleys connect with cables to two separate weight stacks.

The pulley columns are the same columns as the power rack uprights. The pulley, though, does not insert into the large j-hook holes on the front of the uprights. Rather, it inserts into the smaller holes on the inside of the uprights for its height settings.

There are a total of 16 pulley height settings on each column. In comparison, the G9 also has 16 height settings, the G6 has 19 and the G3 has 22. Sixteen settings is plenty to do all the movements you need, at whichever angle you want to hit.

The cable is 16″ high at the lowest pulley setting and 73″ high at the top setting. All the other settings are distributed evenly throughout these min and max heights.

The pulley adjustment mechanism is designed so you can easily change the height setting with one hand. Considering how much you’ll be adjusting the pulley height, this is a nice feature to have. It makes every workout a little bit smoother and less tedious. The G6 and G9 have the same design. The G3 has a different mechanism designed for two-hand operation.

The Monster G12’s standout feature is its selectorized weight stacks. Only the G6 shares this feature. The G3 and G9 are both plate-loaded.

No other feature will improve your workout efficiency more than selectorized weight stacks. The speed at which you can change the resistance is almost instant. You just move the pin to a different hole in the stack. Whereas, a plate-loaded machine can take 20+ seconds if you’re adding or removing a lot of weight.

The weight stack lets you very easily perform drop sets or super sets with virtually no rest between sets. It also means less moving around and handling weights between your sets. It makes you more efficient so you can focus more on actual training instead of preparing to train.

It should also be pointed out that 2 people can use the pulleys at the same since each pulley cable is connected to its own weight stack. This is super helpful if you’re ever training with partner. You save time because you don’t have to wait for each other to finish. This is also possible on the G3 and G6. But it’s not possible on the Monster G9.

Are selectorized weight stacks a “necessary” feature? No. But it is very convenient that can save you lots time, energy and focus.

Obviously, it is a premium feature. So it comes at a cost compared to a plate-loaded setup. It’s $4999, whereas the G9 plate-loaded unit is $3199 and the G3 plate-loaded unit is $2199.

However, if you have the budget and want the convenience and efficiency it affords, it’s worth it! You WILL love it, especially if you do a lot of bodybuilding style training where drop sets, super sets and short rest periods are essential.

Why go with Monster G12 vs the Monster G6? They both have selectorized weight stacks, but the G6 is a full $900 less expensive…

…Well, there’s a few benefits of the G12 over the G6. But the primary advantage is that Monster G12 has a 1-to-1 pulley ratio. This means the amount of resistance is the same as the weight you select.

So if you put the pin in the 81 lb hole for cable curls, then you’ll actually be curling 81 lbs of resistance. This might seem obvious, but many pulley systems have a 2-to-1 ratio, which means the resistance is half of the amount you select.

The G6 has a 2-to-1 pulley ratio. So even though the G6’s weight stacks go up to 221 lbs, you can only get a max of 110.5 lbs of resistance from each one.

The Monster G12 has two 201 lb weight stacks. Thanks to the 1-to-1 pulley ratio, you can get the full 201 lbs of resistance from each stack (up to 402 lbs on double pulley exercises!). That’s plenty of resistance even for very strong lifters.

Monster G12 Functional Trainer with Selectorized Weight Stacks

If you’re really advanced, it’s possible you may need a little extra weight for a bigger movement like cable rows — in which case you can simply do a double pulley version of the movement to take advantage of the second weight stack, or you can buy some 5 lb weight stack add-on plates. But again, most people will never max out this weight stack on any exercise.

So, what does the functional trainer experience feel like? One word: SMOOTH.

It’s the same smoothness as on the Monster G9 and Monster G6, but it does feel a bit smoother than the Monster G3. I think this is because the weights on the G12, G9 and G6 models slide on a track constructed with two cylindrical solid steel rods. Whereas, the weights on the Monster G3 slide on a track made of a single large steel square tube. The G3 is still smooth, just not as smooth as the other models.

Basically, the Monster G12 functional trainer’s smoothness is comparable to that of the pulley units you’ll find in big commercial gyms. You won’t be disappointed.

The Monster G12 functional trainer comes standard with the following cable accessories (click the images below to enlarge them to their full size):

  • Short Angled Bar: This handle is perfect for several cable exercises like biceps curls, triceps pushdowns, underhand rows, overhand rows, upright rows, upright rows and forearm curls.
  • Lat Pulldown Bar: The main use for this popular cable accessory is lat pulldowns (duh!). This includes wide grip lat pulldowns as well as medium grip lat pulldowns (both underhand and overhand). However, this bar has other uses, too, including wide grip cable rows, medium grip overhand cable rows, medium grip underhand cable rows, biceps curls, upright rows, rear delt rows, shrugs, straight-arm pulldowns and more.
  • Nylon Stirrup Handles: These stirrup handles give you more exercise options than any other cable accessory because they allow for complete freedom of hand/wrist position. You can use them for unilateral or bilateral movements. Some of the most popular cable exercises you can do with stirrup handles include: standing chest flyes (low to high, high to low and parallel to floor), lying chest flyes, reverse flyes, lateral raises, one arm rows, one arm presses, bench press, shoulder press, lunges, concentration curls, unilateral underhand triceps extensions, shrugs, and unilateral or bilateral lat pulldowns.
  • Long Straight Bar: I love this bar. It has nice grippy rubber coating and a thick diameter, which makes it comfortable to hold for many cable exercises. It attaches to both pulleys so it’s designed for double pulley cable movements (which you can use up to 402 lbs on) such as squats, split squats, lunges, RDLs, bench press, overhead press, standing chest press, biceps curls, triceps pressdowns, standing rows and seated rows. You can attach it to just one pulley and use it for rotational core movements.
  • Triceps Rope: This is your go-to accessory for triceps pushdowns. It’s also excellent for some other cable movements like overhead triceps extensions, cable crunches, hammer curls, upright rows and face pulls.

These are the same accessories included with the Monster G9, which is the other commercial unit. They will cover you for most if not all of the cable movements you want to do.

That said, there are only 5 cable accessories total included. This is fewer than the number of accessories included with the G3 and G6. This was done on purpose by Force USA, likely because many commercial facilities that buy the G12 will have some of their own accessories already. Also, the accessories included with the G12 are higher quality, at least compared to the G3’s cable accessories.

That being said, it still would’ve been nice to have a couple more accessories included with the Monster G12, particularly for home gym users who don’t have any to begin with. I personally would’ve liked if they included a close grip handle, which is great for seated cable rows and close grip lat pulldowns.

The good news is that it’s easy to find lots quality well-priced cable accessories on Amazon if you feel like you need another type of handle. Though, many people will be perfectly satisfied with just the included accessories.

Lat Pulldown Leg Holder

The Monster G12 comes with a leg holder attachment for lat pulldowns. The purpose is to keep your thighs locked firmly in place so your butt doesn’t lift up during lat pulldowns.

Monster G12 Lat Pulldown Leg Holder Attachment Holding Down Thighs

The attachment consists of a steel bracket with 2 roller pads on the end. Both pads are covered in commercial grade vinyl fabric for long term durability.

You can install the attachment on either of the j-hooks. You insert a pin through the leg holder bracket, then through the j-hook and out the other side. Then there is a pop-pin that you insert into one of the 4 micro-adjustment holes on the base of the j-hook. These holes let you increase or decrease the pad height slightly to get a perfect fit against your thighs.

Monster G12 Lat Pulldown Leg Holder Attachment

The Monster G12 lat pulldown leg holder attachment is designed to be used with a weight bench as the seat. This is different than the Monster G3’s optional lat pulldown leg holder attachment, which combines a seat and leg holder into one piece of equipment.

Force USA Monster G3 Lat Pulldown Seat Attachment
Lat pulldown seat on the G3 model

This is convenient, but the seat does flex slightly when using momentum. I prefer the Monster G12 leg holder since you feel completely stable when you’re sitting on a weight bench.

The leg holder attachment is also designed to be used as a sort of foot plate for cable rows. You install it at the lowest hole on the power rack and plant your feet against the rollers to stabilize your torso and keep from sliding forward during rows. You can forcefully drive your feet into it without issue.

The Monster G9 and Monster G6 both use the same type of lat pulldown leg holder attachment as the Monster G12. However, the Monster G9 has a dedicated low row station with a large steel foot plate inside the unit — As such, you don’t need to use the leg holder attachment for rows on the G9 unless you want to.

Smith Machine

The Force USA Monster G12 Smith machine lets you do a version of just about every barbell exercise you can do in the power rack. Plus, there’s a few exercises you can do only in the Smith machine.

Monster G12 Smith Machine

The Smith machine has gotten a bad rap as being an ineffective machine because it’s a bar on a fixed track — It’s a common “gym bro” belief. But it’s totally wrong…

…While there are some exercises that are best done with a free weight barbell instead of a Smith machine, there are tons of great exercises that you can do on a Smith machine safely and effectively. Here’s some examples:

  • Smith machine front squat (not back squats)
  • Smith machine hack squat (different foot position than regular back squats)
  • Smith machine split squat
  • Smith machine Bulgarian split squat
  • Smith machine incline bench press
  • Smith machine seated shoulder press
  • Smith machine shrug
  • Smith machine power shrug
  • Smith machine RDL
  • Smith machine single leg RDL
  • Smith machine rear delt row
  • Smith machine one arm row
  • Smith machine inverted row
  • Smith machine standing calf raise
  • Smith machine seated calf raise
  • Smith machine glute bridge
  • Smith machine hip thrust
  • Smith machine glute kickback
  • Smith machine incline triceps extension
  • Smith machine biceps drag curl

There’s also A LOT of “booty” exercises that can be done on the Smith machine. I named a few in the list above, but there’s many more creative ones you can find just by searching “smith machine” on Pinterest. This is why the Smith machine is a favorite of many female lifters, and why the G12 is an attractive piece of equipment if it will be used by a woman — whether that’s you, your wife, your personal training clients or your gym members.

The Monster G12 Smith machine has a 770 lb weight capacity rating, as do all the other Monster all-in-one gym models. Virtually nobody needs a higher weight capacity than this for Smith machine exercises.

The G12 Smith machine bar has 12″ long sleeves, which is the same as all the other G-Series models.

Monster G12 Smith Machine Sleeve Length

It would be ideal to have a little bit more length on these, just because there are some people who may only have the super thick “crumb” bumper plates. Those people will only be able to fit six 45 lb plates on the entire bar, or 270 lbs total. However, most people will have thinner bumper plates or regular thin cast iron plates, in which case they can load on more than enough weight.

Monster G12 Smith Machine Safety Catches

The G12 has the same style of Smith machine safety catches that are on the G9 and G6 Smith machines. It’s a steel mechanism that you can slide up and down the Smith machine track. It has a long steel strip that you rotate and place on top of any of the chrome pegs on the adjacent column. It prevents the Smith bar from going any further down.

The idea is to set the safety catches at or just below the bottom of the range of motion for any Smith machine exercise where you could possibly get stuck under the bar if you failed. I advise using it even if you’re using a weight you can easily handle. It’s just a good safety practice to make into a habit.

The G12’s Smith machine action is extremely smooth thanks to its linear bearing design. The up and down gliding motion feels frictionless, with or without weight. It’s just as smooth as the Smith machines on the G9 and G6. However, it’s notably smoother than the G3 Smith machine, which has a bit of drag because it uses a less sophisticated wheel and ball bearing system.

A standout feature of the Monster G12 (and G9) is that it has a counterbalanced Smith machine. There is a mechanism that reduces the Smith bar weight so that it’s 0 lbs when the bar is empty. In comparison, the non-counterbalanced Smith machines on the Monster G3 and Monster G6 weigh 45 lbs when the bar is empty.

You can see the counterbalanced bar in action in the following clip:

This feature lets you do exercises with very light weight. If you’re healthy and somewhat in shape, you’ll probably never need to do a Smith machine exercise with less than 45 lbs.

However, if you’re getting the G12 for a personal training studio or physical therapy practice, this can be very helpful. You may need extra light resistance if you’re training out of shape beginners or individuals undergoing rehab.

Vertical Leg Press

The Monster G12 vertical leg press attachment provides a powerful way to overload your quads, hamstrings and glutes. The quality and ease of operation of the vertical leg press make it one of my favorite stations on the Monster G12.

Monster G12 Vertical Leg Press Attachment

Many people are not used to vertical leg pressing. It can feel awkward to have to lay flat flat on your back to get in position if you’ve never done this exercise before. However, the vertical leg press has a key advantage over the traditional 45 degree leg press: You get a comparable leg workout without having to use as much weight. This means:

  • It’s quicker to load on the weight
  • You don’t need as many weight plates in your gym (which means more money and space savings)

The G12 leg press plate uses the same design as the G9 and G6 plates. It installs onto the Smith machine barbell via a pop-pin on each end of the attachment. The pop-pins snap cleanly into the holes on the Smith machine hooks at the end of the Smith bar. There is no discernible amount of play in the connections. To uninstall it, you simply both both pop-pins out.

Note that you can use the vertical leg press by either laying on a flat bench OR the floor. Laying on a bench is far more comfortable because it’s cushioned. If you use the floor, you may want to put down a couple yoga mats or a thick exercise mat.

The action of the leg press plate is very smooth. You can see the vertical leg press attachment in action in the video below:

I’ll also include a better quality clip of me using the G9’s vertical leg press attachment, which is exactly the same as the one on the G12:

You can use the Smith machine safety catches while leg pressing. This ensures you won’t get pinned if you fail. To use them, simply set them at or just below the bottom of your range of motion.

Monster G12 Vertical Leg Press Attachment - Dont Forget to Set the Safety Catches

I recommend using these safety catches for every single leg press set, even when you’re using light weight. It’s a good habit to develop so you don’t forget to set the safeties the one time you accidentally use too much weight or attempt one too many reps.

The Monster G12 differs markedly from Monster G3 leg press plate. Here’s the key distinctions:

  • The G12 plate has a more angular shape, whereas the G3 plate is more of rectangle.
  • The installation mechanism is different. The G3 plate installs with two lock pins that must be manually inserted through holes in the center of the Smith bar. It’s effective and safe, but is less efficient than the G12 plate’s pop-pin installation. Plus, there’s a slight amount of play in the connection on the G3 (though it feels very stable when you’re leg pressing).
  • The G12 plate comes standard whereas the G3 plate is sold separately.
  • Leg pressing on the G12 feels smoother. This doesn’t have to do with differences in the actual leg press attachments. Rather, it’s because the G12 Smith machine has a smoother action than the G3 Smith machine.
  • The G3 plate is 29″ wide, which is a half-inch narrower than the G12 plate. In practice, this is a negligible difference.
  • The G3 has a spotter rail system. You rotate the rails in or out to rack or unrack the leg press plate.
  • You can optionally lock the G3 plate in place so it stays completely parallel to the floor. This is possible because the G3 has pins you can insert through the Smith bar hooks and the gliding mechanism, thus preventing the Smith bar from rotating. This isn’t possible on the G12 because it has a different Smith machine design (which is superior to the G3’s in other ways).
Monster G12 Vertical Leg Press Attachment vs Monster G3 Vertical Leg Press Attachment

Dip Station

The Force USA Monster G12 dip station attachment consists of two pieces. You install them just like you’d install a pair of j-hooks: One goes on each power rack upright at the same height.

Monster G12 Dip Attachment

The dip station gives you 2 sets of handles, which give you 2 different grip widths to choose from:

  • A narrower 21″ grip width: This is better for doing closer grip dips that target the triceps; and/or for lifters with narrower frames.
  • A wider 27.5″ grip width: This is better for doing wider grip dips that target the chest; and/or for lifters with wider frames.

Each handle is rubber coated and 30mm (1-3/16″) thick. This gives you a comfortable and slip-free grip experience. The diameter is not so narrow that it feels like it’s pressing into the meat of your hand. Yet, it’s not so thick that you can’t give it a good squeeze, which I find can boost overall power on dips.

I like that the G12 dip station is installed on both uprights because it positions you over the midline of the unit. Compare this to a Y-dip bar style of attachment, which installs on a single upright and is common on most traditional power racks — The G12 dip station is better in these ways:

  • It’s a more stable setup since you’re over the middle of the unit, which is its center of balance.
  • You can lean forward as far as you want without any possibility of hitting into an upright.
  • You can face forward or backward. Nothing will be in the way of your feet or head.

Wide and close grip dips aren’t the only exercises you can do on the Monster G12 dip station. There’s several others, some of which aren’t even dip-related movements:

  • Scap dips
  • Inverted rows
  • Inverted shrugs
  • Incline push ups
  • Band-assisted dips
  • And many other unique dip variations

Note that this is the same type of dip station as on the G9 and G6. The G3 does not currently have a dip attachment, though one is in development and will be sold separately once it’s available.

Chin Up Station

Monster G12 Chin Up Station

The Force USA Monster G12 comes with a multi-grip chin up station that consists of:

  • Two oblique bars
  • Four short bars that are parallel to each other
  • Two longer straight bars that are perpendicular to the short bars; both of these bars angle downward at their ends

All of these bar segments allow you to use many different grip positions. At a minimum, you’ll be able to do the following chin up variations:

  • Close pronated grip chin ups
  • Close supinated grip chin ups
  • Close semi-pronated grip chin ups (with a diagonal & straight bar segment)
  • Close neutral grip chin ups
  • Normal width pronated grip chin ups
  • Normal width supinated grip chin ups
  • Normal width semi-supinated grip chin ups
  • Wide pronated grip chin ups
  • Wide neutral grip chin ups

Here’s me demonstrating a few of these chin up variations:

The list above includes just the basic chin up variations that are possible on the Monster G12. There are other less conventional chin up variations you can do as well.

The angled wide grip portions of the chin up bar are rubber coated to enhance grip and comfort — They’re 38mm (1.5″) thick while the bare steel portions are 33mm (1.3″) thick.

Monster G12 Chin Up Station with Rubber Coated Wide Grip Handles

The style of the chin up station on the G12 is the same as on the G6 and G9. It differs from the G3’s “Monkey style” chin up station, but it’s primarily a visual/stylistic difference:

Monster G12 Chin Up Bar vs Monster G3 Chin Up Bar

Functionally, both the G3 and G12 chin up bars let you do most of the same chin up variations — except you can do close grip neutral grip chin ups on the G12, but not on the G3.

One detail that the G3 chin up station has that the G12 lacks is knurling on some of its segments for additional grip. It would’ve been nice if the G12 had knurling, too. But that’s more of a personal preference because the powder coated steel on the G12’s chin up bar will provide enough grip in most situations. If you ever feel you don’t have sufficient grip, you can use lifting chalk, which should always be in your arsenal of gym tools.

Landmine / Core Trainer

Monster G12 Landmine and Core Trainer Station with Handle

The Monster G12 landmine / core trainer station has the following components:

  • Landmine attachment: The landmine consists of a steel sleeve that’s designed to hold one end of your Olympic barbell (there’s also a second sleeve on top that can hold a 1″ diameter standard-sized bar). The landmine is permanently fixed to the base of the power rack. You can install it on the inside or outside of the rack — with the outside being preferable since it’s out of the way. It has a swivel joint, which lets you move the opposite end of the barbell in any direction.
  • Dual-grip handle attachment: The handle is designed for T-bar rows, which is a powerful back building exercise and one of the most popular landmine exercises. The handle slides onto the opposite barbell sleeve. You secure it by putting the weights on after it. The handle is hinged so you can rotate it up or down. It has two sets of grip positions: a straight set for overhand rows and a parallel set for neutral grip rows.
Monster G12 Landmine Station for T-Bar Rows

The landmine / core trainer station delivers a disproportionate number of exercises relative to its size. Many of the movements are core-focused. There’s also plenty of landmine movements that target other muscle parts. Here’s some example exercises:

  • Overhand T-bar row
  • Neutral grip T-bar row
  • Landmine single arm row
  • Landmine standing shrugs
  • Landmine bent over shrugs
  • Landmine rotation
  • Landmine crunch
  • Landmine press
  • Landmine half-kneeling press
  • Landmine front squat
  • Landmine hack squat
  • Landmine overhead squat
  • Landmine split squat
  • Landmine Romanian deadlift
  • Landmine single leg Romanian deadlift

Suspension Trainer Ring

The suspension trainer ring gives you an easy way to further expand the exercise possibilities on the Monster G12.

Monster G12 Suspension Trainer Ring

It provides a fast and convenient way to install a suspension trainer like the TRX (or even a pair of gymnastic rings). You can clip the suspension trainer’s carabiner directly onto the ring, or you can loop its extension strap through it. NOTE: You will need your own suspension trainer since one is not included with the Monster G12.

The ring also ensures that your suspension trainer setup is:

  • Safe: The suspension trainer ring is really a U-bolt that’s installed all the way through the G12’s upper crossbeam. The “U” part of the U-bolt is what you see on the underside of the crossbeam. What you don’t see is the heavy duty hardware securing the U-bolt on top of the crossbeam. The strength of the crossbeam and the hardware ensures the ring can safely support your body weight and then some.
  • Secure: You don’t have to worry about the suspension trainer sliding around since it will be contained within the confines of the ring. Whereas, sliding would be a concern if you attached it around a straight bar or beam.

Here’s a sample of the 80+ suspension trainer exercises you can do, including some of my personal favorites:

  • Suspension trainer chest fly
  • Suspension trainer inverted row
  • Suspension trainer inverted shrug
  • Suspension trainer biceps curl
  • Suspension trainer chest dip (legs behind you, off the floor)
  • Suspension trainer triceps dip (legs in front of you, on the floor)
  • Suspension trainer triceps extension
  • Suspension trainer reverse fly
  • Suspension trainer Bulgarian split squat
  • Suspension trainer hamstring curl
  • Suspension trainer plank
  • Suspension trainer mountain climbers

The suspension trainer ring is NOT just for hanging a suspension trainer. You can also loop a resistance band through it for band exercises such as:

  • Band triceps pulldown
  • Band lat pulldown
  • Band straight arm pulldown
  • Band high-to-low row
  • Band face pull
  • Band high-to-low woodchop
  • Band-assisted dips / pull ups (performed by stepping into the bottom loop of the band to effectively reduce your body weight)

Accessory Storage

The cable accessory storage area is located on the rear panel inside the Monster G12.

Monster G12 Accessory Storage Area with 4 Storage Hooks

There are 4 storage hooks on the panel. This provides enough space to fit all the included accessories, except for the long straight bar, which you’ll have to prop up against the panel since it’s too long to hang on one of the hooks.

You’ll also be able to fit any other cable accessories you may own on these hooks since you can fit multiple accessories to a hook. Still, I would’ve liked if there were one or two more storage hooks so you could spread things out more.

The rear panel is not just the storage area. It also displays a large exercise diagram showing 37 movements — most of which are done on the functional trainer.

Monster G12 Accessory Storage Area

The exercise diagram is particularly useful for anyone using Monster G12 who’s not very familiar with the capabilities of a functional trainer. This could include you, a training partner, a family member, personal training clients or people using it in a facility.

The chart shows the same 37 exercises that the Monster G6 displays on its accessory storage board. In comparison, the G9 displays only 18 exercises and the G3 displays none.

Weight Plate Storage

Monster G12 Weight Storage Area

There is a dedicated weight storage area in the rear of the Monster G12. It consists of 6 total plate holders, with 3 on the left side and 3 on the right. This gives the vast majority of users more than enough space to store all their weights.

Each weight storage holder is 8 inches long. The number of plates you can fit on the pegs depends on the type of plates you have:

  • If you have basic cast iron plates, you can fit four 45 lb plates on each holder
  • If you have competition bumpers, you can fit three 55 lb plates or four 45 lb plates on each holder
  • If you have super thick hi-temp bumpers, you can fit two 45 lb plates per holder

Having 6 plate holders is enough to organize your plates by weight: 45s on the bottom, 35s on the middle, and 25s and under on the top — or a similar configuration.

It’s so much easier to add and remove plates from the bar or pulley when your plates are stored in an accessible way. Your workouts become more efficient and you have more time to rest between sets.

A great but not-so-obvious feature of the weight plate holder pegs is that they’re angled ~30-40 degrees forward. The benefit of this is that it saves space because the unit can sit flush against a wall. If the weight holders were pointed straight out to the sides, the unit would have to be several inches away from the wall so the plates could fit.

Another side benefit of this angled weight holder setup is that puts the plates a little bit closer to the Smith machine. This makes the transfer of plates from bar to peg (and vice versa) more efficient.

The outer part of the plate holder can be removed to reveal a narrower 1” diameter peg that fits standard sized weight plates. This is a neat feature if you have a bunch of standard plates in your gym, though most people will have Olympic plates only.

Barbell Storage

The Monster G12 has vertical barbell storage on one side of the rack, toward the rear. This provides a convenient spot to store your barbell when not in use.

Monster G12 Barbell Storage

There is a holder for an Olympic barbell (~2” sleeve diameter) and a standard barbell (1” sleeve diameter).

You need additional ceiling clearance above the max height of the Monster G12 to store a full sized Olympic bar. As long as your ceiling is at least 7’11” tall, you’ll be able to store your bar here. This accounts for the extra distance you need to lift the bar into and out of the storage sleeve.

If your ceiling is too short, you can always buy a wall-mounted storage solution like this vertical storage hook or this horizontal storage rack. Or you can simply store the bar on the j-hooks when you’re finished training.

Olympic AND Standard Compatibility

As mentioned in the sections above, ALL aspects of the Monster G12 are compatible with both Olympic and standard bars and plates, including:

  • Barbell storage
  • Plate storage
  • Smith machine
  • Landmine attachment

Most people won’t ever use this feature. However, there are plenty of home gym owners who have a ton of standard plates to go along with their standard spin lock dumbbells and/or barbell set.

Color Options

The Monster G12 comes in gray by default. However, you can upgrade to blue or red for $300. This is the same for the Monster G9, since it’s also a commercial unit. You don’t get this option on the non-commercial G3 and G6 units.

Monster G12 Color Options

The colored parts of the unit include the pulley and the frame reinforcement plates.

Opting for the red or blue color is an easy way to make your gym more vibrant. Red and blue are great choices particularly if you’re getting the Monster G12 for a police or fire department gym — or just if you like red or blue, regardless of where you’ll be using it!

If you decide to get one of the premium color upgrades, you’ll receive the colored parts in a separate box that will arrive on the same shipping pallet as the main package. The main package will also come with the default gray pieces, too…

…So, you’ll actually receive 2 sets of colored pieces: gray AND either red or blue. You can mix and match the gray with your premium color choice if you like. Or you can save the gray option in case you want to switch up the G12’s color in the future.

Missing Features

Band Peg Holes

Like the Monster G9, the G12 has no band peg holes. You won’t be able to perform band squats, band bench or other band-resisted movements. You also won’t be able to add band resistance to the Smith machine or pulley weights.

If that’s something you really want to do, you should go with the G3 or G6, which both have band peg holes along their base…

…But what if you love everything else about the G12, and just wish you could do band work on it?

Well, don’t give up on your dream of owning the Monster G12 just yet.

There is a DIY workaround for getting band pegs: You can install a set of mountable band pegs outside of the G12. You’d simply bolt them into your into your concrete floor or your lifting platform if you have one. This is a surprisingly affordable option and an easy DIY project if you have some basic handyman skills.

Bolt-down Capability

You can’t bolt the Monster G12 to the floor.

But luckily, there’s no real need to do so because:

  • The Monster G12 is a behemoth of a machine, as is. It feels rock solid even without any weight plates on it. This is because it’s commercial grade, has a significantly wider frame than the residential models and has whopping 402 lbs of selectorized plates built into — for a total unit weight of 950 lbs!
  • It doesn’t have any band pegs on the base of the unit. So you won’t be doing any heavy band squats, which would require more stability to keep the band tension from potentially shifting the unit around.

It should be pointed out that the G12 may appear to be a bolt-down unit because there are holes in the feet:

Monster G12 Does Not Have Bolt-Down Capacity

However, I checked with Force USA and they confirmed these are not designed for bolting down. They don’t recommend trying to use them for that because:

  • The hole diameter wouldn’t fit a 5/8″ bolt, which is the typical size needed for safely bolting down a rack.
  • The feet plates with the holes in them aren’t welded to the frame (meaning they’d be a weak point).
  • There’s no holes on the rear of the rack; only on the two front feet.

I would’ve said it might be okay to put smaller bolts through these holes if you were doing it only to prevent shifting over time (as opposed to for safety/stability reasons) — But even that would be pointless since the unit weights nearly 1000 lbs before you add any weights on. It’s just not gonna budge from regular use.

Shipping

The Monster G12 will ship to the 48 contiguous United States. The shipping cost is only $199, which is very reasonable considering the size and weight of the Monster G12 package.

The unit ships in 2 wood boxes. The first is a larger, coffin-like box weighing 500+ pounds. The second is smaller, but houses the two stacks so its a little over 400 pounds.

It ships via freight and will arrive packaged on a pallet. Freight shipping brings down the shipping cost and reduces the likelihood of damage compared to traditional ground shipping (i.e. UPS, FedEx).

Who Is the Monster G12 Best for?

The Force USA Monster G12 has a few different use cases.

The first use is for physical therapy practices or personal training studios. Here’s why:

  • The G12 has a commercial use warranty. It can take the daily wear and tear it would receive in a PT clinic or personal training studio.
  • It has selectorized weight stacks. This feature is indispensable in a physical therapy or personal training setting, because it allows for rapid weight change when time is limited for the session.
  • It has a counterbalanced Smith machine. This makes the starting weight 0 lbs. This is essential if you’re using it to train individuals who are too weak to lift a 45 lb bar. In contrast, non-counterbalanced Smith bars start at 45 lbs.

The Monster G12 is also the best option for home gym owners looking for the most premium all-in-one home gym solution. In addition to wanting the most premium model, these home gym owners will be using it for general fitness, bodybuilding-focused training or serious but traditional strength/resistance training (i.e. not necessarily powerlifting-specific). Here’s why:

  • Like the G9, it has the most robust build quality available in the Monster G-Series. While you may not need commercial quality in your home gym, it’s nice to have it.
  • Like the G6, it has the “luxury” feature of selectorized weight stacks. This lets you change the weight on the pulleys almost instantly.
  • The inclusion of the selectorized weight stacks makes the G12 great for bodybuilders. That’s why I also recommended the G6 for this demographic. A selectorized system makes it MUCH easier to do drop sets and supersets, which are staples in bodybuilding training. The G12’s weight stacks are even better for bodybuilders than the G6’s because the G12 has a 1:1 weight ratio vs 2:1 for the G6. This means each of the G12’s 201 lb weight stacks allows you to select up to 201 lbs of resistance. Whereas, each of the G6’s 221 lb weight stacks only allow you to select up to 110.5 lbs of resistance. That’s nearly twice as much resistance for the G12. Most people will never outgrow the 201 lb stacks on the G12, but they may outgrow the G6 stacks for some exercises (Note: You can progress beyond 110.5 lbs on the G6 by using the band pegs to add band resistance to the weight stack, but that’s an extra step that’s not needed on the G12).
  • You can do anything you’d need to do on the G12 for a serious strength training regimen: All the basic barbell movements. Plus, any functional trainer movement — And again, you can go all the way up to 201 lbs of resistance per side, which people who are serious about improving strength will appreciate. However, I say the G12 is not necessarily the best choice for a powerlifting-focused type of strength training because it lacks Westside hole spacing and band pegs — both of which are important features for many powerlifters. The G3 is arguably a better option for powerlifters seeking an all-in-one gym.

Other great Monster G12 use cases are for hotel gyms and corporate/office gyms. Here’s why:

  • The average hotel gym and corporate gym are relatively small and have limited equipment. The G12 provides a commercial-warrantied all-in-one gym solution that will add a ton of exercise variety in a compact footprint.
  • The users will actually be able to get an intense and heavy training session in. If you’ve been in many hotel or office gyms, you’ll know how poorly equipped they are for people who actually want to do an effective resistance training workout.
  • The selectorized weight stacks are perfect for hotel and corporate gyms. It keeps the gym area cleaner and more organized because the users don’t have to load plates on and off the pulley system. This is important because these gyms usually aren’t staffed. Anything that keeps the training area less cluttered for other users is a win for these types of gyms.

The Monster G12 is also a practical gym solution for fire departments, police departments and military bases. Here’s why:

  • The G12 has a more robust frame that can withstand regular daily use from multiple people in a commercial setting. Force USA stands behind it with a lifetime commercial warranty.
  • You can order the G12 in red, which is ideal for fire departments; or blue, which is ideal for police departments. And either red or blue works great for any US military gym.
  • While the G9 is also a good choice for police/firefighter/military gyms since it too has a commercial warranty, the G12 has one major advantage over it: It uses two heavy selectorized weight stacks that provide more convenience and efficiency than the G9’s plate-loaded system. The ability to complete workouts faster can be a major benefit for police/firefighters/military personnel who often can be squeezed for time.

Lastly, the G12 is a good match for small rec centers and fitness centers. Here’s why:

  • These gyms usually don’t have a ton of floorspace to begin with. And much of the room they do have is likely taken up by cardio equipment. The G12 provides everything needed to cover all the bases for strength training equipment; all in a single unit that takes up minimal floorspace.
  • These types of gyms are usually low-traffic. You’ll rarely have the issue of multiple people waiting to use one of the 8 stations on the G12. In the cases where there are multiple people in the gym at once, you can have two people doing different exercises on each cable column. This is a big advantage over the commercial G9. Although the G9 can also work well for these types of small gyms, you can’t have two people simultaneously using the functional trainer.

Monster G12 vs Monster G3 vs Monster G6 vs Monster G9

All of the Monster all-in-one gym models have their own unique set of features and pros and cons. So it can be difficult to decide which is best for you.

If you’re still unsure if the Monster G12 is the best unit for your needs, I urge you to read my Force USA Monster G3, G6, G9 & G12 review and buying guide. It will help you compare the four models across all the key features and specs.

  1. Good afternoon Alex, I am writing from Spain because I have read your comparisons of the Monster Usa.
    I have a couple of doubts :

    1) The handles (accessories included) once placed in the double pulley, could be turned and oriented each one on its side towards the ends of the smith machine bar and / or the outer bar to use as weight, instead of discs ?
    It sounds a bit weird, but it could be an option to save items, money and even gain speed in the loads of those bars.

    2) Could a punching bag be placed in the suspension training ring?

    Anxious of your answer, if it’s graphic, the better.
    Receive a cordial greeting.

    1. Hi Javier, I’m a bit confused on your first question. I read it several times but am not quite sure what you’re asking. Can you try explaining again?

      As for your second question, yes you could put a punching bag on the suspension trainer ring. It’s plenty strong to hold it up. And the G12 frame has 400 lbs of selectorized weights holding the rack securely on floor.

  2. Buenas tardes Alex de nuevo.
    Lo lamento por no explicarme bien.
    Te replanteo la primera pregunta.
    Se podría de alguna manera usar las pilas de peso con las barras (mediante algún adaptador ) , algo similar a la FT2 de Inspire . Así se podría ganar velocidad en los cambios de peso e incluso ahorrar dinero en la compra de discos .

    Gracias Alex por responderme a las dudas .
    Gran trabajo .
    Recibe un cordial saludo .

    1. Hey Javier, sorry I missed this follow up question, initially. I think I understand what you’re asking this time, thanks to Google Translate 😀

      To answer your question: No, it’s not possible to attach the weight stack pulleys to the Smith machine like you can on the Inspire FT2. The only reason this is possible on the FT2 is because it doesn’t have a power rack area, and its pulleys are lined up with its Smith machine. Whereas, the pulleys on the G12 are on the power rack columns, which are in front the Smith machine track. Meaning, you couldn’t attach the weight stack pulleys to the Smith machine bar even with some kind of DIY adapter.

      Inspire Fitness also has the SCS model, which has a power rack, Smith machine and pulley system — And it also cannot connect its weight stacks to the Smith machine for the same reason (because its power rack is in front of its Smith machine track).

  3. Hola buenas quisiera poder hacer la misma pregunta que el compañero, se pueden utilizar las placas con la barra Smith? O solo funciina con discos?

  4. Perdona el correptor cambio mis palabras, se pueden utilizar las columnas de placas con la barra Smith o solo se puede trabajar con discos olímpicos?

    1. Hi Gonzalo, I believe I answered your question when replying to a previous comment from Javier. You can jump to that comment here for my full response. In summary, though, it’s not possible to connect the pulleys to the Smith machine. Instead, you have to use weight plates on the Smith machine for resistance.

    Hi Alex,
    I found your review of the G 12 helpful and extremely thorough. I am drawing a comparison between the G 12 and the brute force 360 PTX from a company called renouf fitness, and would appreciate any of your thoughts and comments as to which of the two you would recommend. I know that the brute force machine has an extra attachment which is quite unique and monetarily is nearly $1200 less but I don’t know if I’m giving up quality with the less expensive model I do want a good high-quality machine.
    Thank you, Ron

    1. Hi Ron, I’ve come across the 360 PTX in my research, and while it looks intriguing, I haven’t been able to find any detailed feedback from actual customers. The stuff I saw was all from promotional materials. And of course, I haven’t tested one myself, though I would love to.

      I wish I could be more helpful to give you some insights for comparison. All I really know is that the Monster G12 is definitely high quality since that’s the only I’ve had hands-on experience with.

  6. Hello,

    Was wondering for the G12 can I purchase after market 2 by 2 j-hooks for replacing these, and maybe only use the stock hook when I lat pull down. Thank you.

    1. I haven’t personally tested this, but as long as the j-hooks you find are indeed 2″x2″ and designed to fit in 1″ diameter holes, it will work just fine.

  7. I’m between the Force USA G12 and the Inspire FT2. Any thoughts between these two machines? Thanks so much and great review!

    1. I’d definitely go with the Monster G12 over the Inspire FT2, since the FT2 does NOT have a power rack area.

      A fairer comparison would be the Monster G12 vs the Inspire SCS, since the SCS has a power rack area. I haven’t used the SCS personally. But based on researching the SCS and having used the G12, I would give a slight edge to the Monster G12. Here’s the main reasons why:

      • The Monster G12 has 2 x 200 lb weight stacks with a 1:1 ratio, giving each side a resistance of 200 lbs, or 400 lbs if using both. Whereas, the SCS only has 2 x 165 lb weight stacks with a 2:1 ratio, giving each side a resistance of 82.5 lbs, or 165 lbs if using both (NOTE: You can purchase separately weight stack add-ons of 2 x 50 lbs and 2 x 5 lbs [also 2:1 ratio], which would give you a max weight of 110 lbs per side or 220 lbs if using both.) To summarize, you can use a lot heavier resistance on the G12 than on the SCS.
      • I like how the G12 has the power rack on the outside (i.e. like a half rack). Whereas, the SCS’s power rack is inside the unit, and is contained in the rear by the Smith machine track. This makes the SCS power rack potentially feel a bit too narrow for some people — There’s enough space, but I prefer being able to walk back further for some exercises, which the G12 allows for. This point comes down more to personal preference.
  8. I got my Force USA G12 yesterday and put it together today. After assembling I went to rack the Force USA Colored Bumper Plates that I received a few weeks earlier and they don’t fit on the weight holders of the G12 or the Smith Press Bar. I can jam with excessive force to get the 25/35 pounders on but it requires the same excessive force to get them off. The 10, 45 and 55 pounders won’t go on at all not even a half inch. I’m not sure if this is a problem with the bumpers or the G12 pegs/smith bar. I was wondering if you had any problems loading/storing the bumper plates? I would assume they should be nice and smooth on and off the bar/holders. Thanks for your time!

    1. Hey Chris, sorry to hear about that. No, I didn’t have that issue when loading the bumpers on the weight pegs or the Smith bar.

      Worst case, you can always remove the Olympic sleeve adapter portion (on both the Smith machine and the weight pegs) to reveal the 1″ standard sleeves/pegs. Of course, that’s not ideal, and I would recommend reaching out to Force USA customer service to see about your specific issue.
