7 Best Adjustable Dumbbells for Home Gyms in 2025: PowerBlock vs Ironmaster vs Bowflex & More

If you’re trying to build a high quality home gym on a budget, then you’ll want the best adjustable dumbbells you can afford.

Sure, a full set of fixed dumbbells would be nice. However, you can the same benefits of dumbbell training with a good adjustable dumbbell system, at a fraction of the cost and with a fraction of the space requirements as a fixed dumbbell set.

In this article, I’ll teach you all about adjustable dumbbells, including their benefits, the different types and what to look for when buying them. Then, I’ll lay out my top 7 picks for the best adjustable dumbbells, including the pros and cons of each system.

For my top picks, summarized in the table below, I’ve chosen to include only heavy adjustable dumbbell systems. Each dumbbell set must be able to adjust to at least 70 pounds per dumbbell.

I’ve also included many other, lighter, dumbbells that didn’t make the cut as one of the “best adjustable dumbbells,” in a separate section later on this page.

Now, let’s get started! You can start reading the full article, or jump to a specific part of it by using the table of contents below:

Advantages of Adjustable Dumbbells vs Fixed Dumbbells

While you may be accustomed to using that long line of dumbbells at your local gym, adjustable dumbbells are far more convenient. Adjustable dumbbells only require you to buy two pieces of equipment, which will save you the hassle of transporting dozens of traditional fixed dumbbells. What’s more, you only need a small corner space to store adjustable dumbbells.

Compared to a fixed dumbbell set, a pair of adjustable dumbbells is the more cost-effective option. For example:

• The price of the Rep Fitness 5-100 lb Rubber Hex Dumbbell Set (fixed DBs) is a whopping $2379. This doesn’t include shipping, which is an extra ~$300+. Keep in mind this is one of the better priced fixed dumbbell sets available. The dumbbells go from 5-100 lb in 5 lb. increments.
• The price of my #1 rated dumbbell, the PowerBlock Pro EXP Stage 3 Set is only $737 plus shipping. It goes from 2.5-90 lbs in 2.5 or 5 lb increments.
• So, the fixed set in this example is ~300% more expensive than the adjustable set!

Are All Adjustable Dumbbells the Same?

Adjustable dumbbells, unlike most commercial gym dumbbells, are quite different from one another.

First, the size and shape of adjustable dumbbells can vary drastically.

Some may be top heavy while other brands may balance the weight throughout. Some adjustable dumbbells may have a circular shape while others have a block or boxy shape. You may find that you prefer one size and shape over another so it’s important to take this into consideration.

Next, the method in which you change the amount of weight you’re using can be very different depending on the adjustable dumbbell. Some dumbbells have a twist-action change while others have movable pins.

Finally, not all adjustable dumbbells are built the same. If you’re someone who tends to get rough with their gym equipment, you’ll want to avoid certain brands of adjustable dumbbells because of their durability.

With all of these differences to consider, let’s jump into the top 6 adjustable dumbbells for home gyms.

The 7 Best Adjustable Dumbbells for Home Gyms

#1 PowerBlock Pro EXP Stage 3 Adjustable Dumbbells

PowerBlock is one of the veteran brands in the fitness industry for adjustable dumbbells…

…They have several different models with different features and weight capacities.

Out of all the available models, the PowerBlock Pro EXP Stage 3 set is by far the best one you can buy. That’s why I bought one for myself recently (Jan. 2019)! I’ll tell you exactly what makes the Pro EXP the best adjustable dumbbell on the market in the section below:

PowerBlock Pro EXP Stage 3 Pros

If you want all the details on this dumbbell set, you can check out my in-depth PowerBlock Pro EXP review. Otherwise, I’ve included the key highlights below:

• The PowerBlock Pro EXP is the most durable and robust PowerBlock dumbbell set you can buy. Unlike the Elite 90, it has a protective urethane coating on the weight blocks. Plus, the weight block rods have a non-welded “flex” design. This makes them MUCH less susceptible to damage from short drops compared to the Elite, which uses an inflexible welded design.
• They go all the way up to an impressive 90 lbs per hand, just like the Elite 90.
• They’re the only PowerBlock dumbbells that are compatible with the KettleBlock handle, which converts them into an adjustable kettlebell. Similarly, they’re the only models that are compatible with the PowerBlock EZ Curl Bar and Straight Bar attachments, which convert the dumbbells into adjustable barbells.

PowerBlock Pro EXP Stage 3 Cons

• The PowerBlock Pro EXP Stage 3 adjustable dumbbells are more expensive than the Elite 90 set by about $200, which might be out of the budget range for some lifters.

#2 PowerBlock Elite 90 Adjustable Dumbbells

If you’re on a budget that doesn’t allow you to get the PowerBlock Pro EXP set, but you still want a proven adjustable dumbbell set with rapid adjustment, then the PowerBlock Elite 90 set are a superb choice.

PowerBlock Elite 90 Pros

• Easy and quick to adjust, a pair of Elite 90 adjustable dumbbells are maxed-out at 90 pounds, which means that they are going to be ideal for the greatest number of weight lifters regardless of physique goals. In terms of quality, the Elite 90 set was built to take some punishment. Still, I wouldn’t recommend throwing them around as you would with traditional dumbbells.

PowerBlock Elite 90 Cons

• The biggest complaint that you’ll hear about the Elite 90 adjustable dumbbells is that due to their box-like shape they can be awkward to handle. This, of course, can be remedied with time and practice.

NOTE: I also highly recommend the PowerBlock Sport EXP dumbbells. They’re right up there with the PowerBlock Elite dumbbells. In fact, I would have included them in this list of best adjustable dumbbells, but I didn’t want ALL of the top positions to be dominated by PowerBlock models, since they’re quite similar.

If you’re interested in the PowerBlock Elite or Sport dumbbells, I recommend you check out my PowerBlock Elite Series vs Sport Series guide for an head-to-head comparison of these two models. You may also be interested in my PowerBlock Elite Series vs Pro Series guide as well as my Sport Series vs Pro Series guide.

#3 Ironmaster Quick-Lock Adjustable Dumbbells

With the ability to max out the weight at 165 pounds per dumbbell and the durability of commercial grade gym equipment, the Ironmaster Quick-Lock Dumbbells are a formidable choice.

Ironmaster Dumbbell Set Pros

• You can expand them to VERY heavy weights. The base set goes to 75 lbs., which is impressive in and of itself, and adequate for most lifters. Need more weight than that? No problem, just get the 120-lb add-on kit. Is 120 lbs. still too light for you?! Well worry not, there is yet another add-on kit that takes you all the way up to a max weight of 165 lbs.! That’s almost the highest you can go for any adjustable dumbbell set. The only one I’ve seen that can go higher is one of the commercial sets from PowerBlock that goes up to 175 lbs. However, it’s also significantly more expensive than the Ironmaster — And with the Ironmaster, you can start with a much lower investment by getting just the base set, then buy the add-on sets later.

• I really like this adjustable dumbbell pair because of the potential that comes with purchasing them. They are a vital tool for any fitness goal and they are built so tough that I believe they are going to last a long time once you make the buy.
• It comes with the dumbbell stand included in the price of the 75 lb. base set. With most other adjustable dumbbell sets, you have to buy the stand separately.

Ironmaster Dumbbell Set Cons

• The Ironmaster Quick-Lock Dumbbells aren’t the fastest locking dumbbells. They are much quicker than traditional spin-lock adjustable dumbbells. But they can’t compare to the speed of the PowerBlock or BowFlex brands. At the same time, though, they are more durable than both the PowerBlock and BowFlex dumbbells – you trade adjustment speed for durability.

#4 Bowflex SelectTech 1090 Adjustable Dumbbells

No products found.

Bowflex SelectTech 1090 Pros

• With a weight limit of 90 pounds that you can rapidly spin and set, the Bowflex SelectTech 1090 adjustable dumbbells are a great choice for anyone looking to build a respectable home gym.
• The 1090 dumbbells are reasonably priced for the quality and while not as tough as the Ironmaster dumbbells or even the PowerBlock dumbbells, they’re more durable than most other adjustable dumbbells.
• While I don’t own the 1090s, I did have the opportunity to train with them before. I found that the handle of the 1090 dumbbells helped me train up my grip strength considerably more than traditional dumbbells, because it’s thicker.
• You can buy the Bowflex dumbbell stand separately, or included with the dumbbells.

Check Current Price – Bowflex SelectTech 1090 Adjustable Dumbbells »

Bowflex SelectTech 1090 Cons

• The Bowflex SelectTech 1090 adjustable dumbbells start at a relatively high weight of 10 lbs. This isn’t an issue for the vast majority of exercises, but there are times where being able to go as low as 5 lbs. (e.g. rotator cuff exercises like shoulder external rotation and shoulder internal rotations).
• They are the same length at 10 lbs. as they are at 90 lbs. They don’t get shorter/longer as you adjust the weight lower/higher. This can make it awkward to do exercises like biceps curls or lateral raises where you bring the dumbbells to your sides or in front of you — the long handles may get in the way of your hips or thighs, even when using a relatively weight.

#5 Merax Deluxe Adjustable Dumbbells

The Merax Deluxe dumbbell set is a dial-based selectorized adjustable dumbbell set that goes from 11-71.5 lbs per dumbbell in 5.5 lbs (2.5 kg) increments. This relatively little-known dumbbell set delivers a good value, making it a major competitor to the Bowflex 1090 and 552 sets.

Merax Adjustable Dumbbells Pros

• Very rapid adjustment; you only have to adjust dial from one end, instead of from both ends.
• Goes all the way up to 71.5 lbs per dumbbell, which is impressively high especially considering the relatively low price point.
• You can buy a stand bundled with the dumbbells, or you can buy a stand separately later.
• The price is attractive for the features and quality on this type of dial-based selectorized adjustable dumbbell system.

Merax Adjustable Dumbbells Cons

• Weight is shown in kilograms; not pounds.
• The dumbbells are the same length (16.4 inches) at every weight. It will feel excessively long when using lighter weights. It might get in the way when doing exercises like curls and side raises.

#6 Yes4All 200-Pound Adjustable Dumbbell Set (100 Lbs per Dumbbell)

When you want the feeling of holding a traditional dumbbell and the option to expand your weight limit to 100 pounds per dumbbell, the 200-pound set of Yes4All Adjustable Dumbbells may be what you need.

Yes4All Adjustable Dumbbells Pros

• It’s one of the best value set of twist-on collar style adjustable dumbbells I could find that adjust up to 100 pounds per dumbbell.
• Do not confuse the 200-pound set with the 105-pound version of the Yes4All dumbbells. The 105-pound set only comes with enough weight plates to adjust each dumbbell up to 52.5 pounds per dumbbell. If you’re a serious lifters, you’re going to want use more than that eventually, on some exercises.
• Of course, if you did get the 105-pound set, you could buy more plates later on so that it’s effectively the same as the 200-pound set. BUT there’s a catch: You can’t buy just any standard weight plates. You can only buy plates that fit the 1.15″ diameter handle (the standard size is 1 inch). Yes4All sells these, but when you buy them separately from the dumbbell set, they’re more expensive than many other 1 inch standard weight plates……All of the above just lends itself the 200-pound set being the smartest buy to begin with–even if you don’t think you’ll need more than 52.5 pounds per dumbbell at first, you will eventually. So you may as well buy it now and save. That is, of course, if you choose Yes4All dumbbells vs the others I mention in this article.

Yes4All Adjustable Dumbbells Cons

• The issue that I have with the Yes4All Adjustable Dumbbells is the twisting cap that secures the plates. It is quick to wiggle and become loose. I think this won’t be a problem for the observant lifter but if you tend to get into the zone, you may not realize you’re about to lose some weight plates.

#7 Cap Barbell Olympic Dumbbell Handles

If budget is your main concern when buying adjustable dumbbells, the Cap Barbell Olympic Dumbbell Handles is a low-cost option that gets the job done.

Cap Barbell Olympic Dumbbell Set Pros

• It gives you that old school feel of traditional dumbbells with the Olympic-style plates. What’s more, you can rest assured that you’re getting a set of dumbbells with a high durability level.
• Weights are not included if you already have an Olympic weight set already (i.e. plates with 2-inch diameter hole), then you can just buy 2 handles and use your existing weight plates.

Check Current Price – Cap Barbell Olympic Dumbbell Handles »

Cap Barbell Olympic Dumbbell Set Cons

• With Olympic plates, you can really only use 10 lb plates as the heaviest plate you put on the handles (unless you have deep dish 25 lb plates, which are shorter). The reason is that heavier plates have larger diameters and will get in the way on most exercises. As such, you’ll likely need to buy several pairs of 10 lb Olympic plates if you want to add a lot of weight on, unless you already

In addition to my top picks for the best adjustable dumbbells, above, I’m also including reviews for dozens more adjustable dumbbells in this section.

This is basically ALL of the adjustable dumbbell sets I could find online, as of late 2018. Most are mediocre and some are downright terrible. But there are a few good ones mixed in here.

Without further ado, here are all other adjustable dumbbell reviews for you to peruse:

MX Select MX55 Adjustable Dumbbells Review

Here’s the pros, cons and key features of the MX Select MX55 dumbbell set:

• Adjusts from 10-55 lbs per dumbbell.
• Adjusts in increments of 5 lbs when adjusting both ends evenly. However, you can adjust just one end to get increments of as little as 2.5 lbs; the weight distribution will be slightly uneven, but you can just shift your grip position a bit to balance it out.
• Sold as a pair.
• Rapid and seamless adjustment.
• Comes standard with a sturdy, sleek-looking stand with built-in adjustment trays.
• One of the most “natural” adjustable dumbbell designs. It has a very similar look and feel to a traditional fixed dumbbell.
• Great choice if you only need an intermediate max weight (goes up to 55 lbs per dumbbell)

Bowflex SelectTech 552 Adjustable Dumbbells Review

Here’s the pros, cons and key features of the Bowflex SelectTech 552

• Adjusts from 5-52.5 lbs per dumbbell.
• Adjusts in 2.5 lb increments from 5-25 lbs. Then it adjusts in 5 lb increments from 25-50 lbs. The last increment is 2.5 lbs., from 50-52.5 lbs. All of these increments are for when the weight on the dumbbell is evenly balanced. Since you adjust each side of the dumbbell independently, you can technically cut these increments in half if you’re okay with the weight being slightly imbalanced toward one side. This means you could get 2.5 lb increments in the 25-50 lbs range (e.g. if you wanted 27.5 lbs, you’d adjust one side to 25 lbs and the other side to 30 lbs). Similarly, you could get as little as 1.25 lb increments in the 5-25 lbs range (e.g. if you wanted 21.25 lbs, you’d adjust one side to 20 lbs and the other side to 22.5 lbs). Admittedly, there’s no practical situation where you’d need a 1.25 lb increment when dealing with already light weights, but hey, it’s possible. The 2.5 lb increment possibility in the higher weight range of 25-50 lbs has more practical applications.
• Sold as a pair
• Comes with dumbbell storage trays. There is also a dumbbell stand available which you can buy bundled with the dumbbell set or you can buy it separately.
• Overall, the Bowflex 552 dumbbells are very well balanced. They’re perfectly balanced from side to side. From top to bottom, they have good balance for their dial-based selectorized design, but it’s not perfect. All dial-based selectorized dumbbells have a cut-out gap in each weight plates on the top side of the dumbbells, which is needed so the handle can be inserted into the center of the plates. This design causes some degree of imbalance between the top and bottom of the dumbbells. Bowflex managed to minimize this imbalance by keeping the gaps as small as possible, in addition to making the bottom sides of the plates flat. Still, on heavier weights, you may notice that they’re slightly bottom heavy. They may feel like they’re trying to rotate down depending on how you’re holding them. To mitigate this, make sure the dumbbells are in the same position in both hands. Also, have the dumbbells oriented so that the gap part is either facing straight up or straight down, relative to the dumbbell path on whichever exercise you’re doing. For most people most of the time, this won’t be a noticeable issue since the effect is so subtle.
• The handle shape is contoured, being thickest (1.5″ diameter) in the center and narrower toward each end. The handle material is metal, though it’s mostly covered by a texturized rubber grip portion where you grasp the handle. The metal shows on either side of this grip. Unfortunately, it’s a common complaint that this rubber grip will eventually loosen and shift/rotate slightly around the handle during use; though it typically takes a while for this to occur.
• 15.75 inches long
• Dumbbell length is the same regardless of the amount weight selected.

Core Fitness (StairMaster TwistLock) Adjustable Dumbbells Review

Here’s the pros, cons and key features of the Core Fitness adjustable dumbbell set:

• The Core Fitness adjustable dumbbells have the same exact design as the StairMaster TwistLock adjustable dumbbells, which are increasingly difficult to find in stock online. It appears that the company that owns StairMaster (Core Health & Fitness) is rebranding the same dumbbell design under the name of “Core Fitness.” Luckily, these retail at a MUCH lower price than the StairMaster branded version did (i.e. ~$600 for the StairMaster vs. ~$300 for the Core Fitness the last time I checked).
• Adjusts from 5-50 lbs per dumbbell.
• Adjust in 5 lb increments. The weight is distributed evenly between the left and right side at every weight setting. This is in contrast to some dumbbells where the weight can be adjusted asymmetrically.
• Sold as a pair.
• They come with a tray to store and adjust each dumbbell in. There is a well-made and reasonably priced dumbbell stand made for the Core Fitness adjustable dumbbells, which is sold separately (there’s also this one), which is the exact same but with “StairMaster” branding). You don’t need it per se, but I always recommend some type of stand for any adjustable dumbbell system, since it put trays and dumbbells at a convenient height for racking and unracking, so you don’t have to pick them up from the floor each time.
• Incredibly easy and fast adjustment. The “TwistLock” adjustment mechanism only requires one hand to adjust weight. You just grasp the handle and twist it to the desired weight setting, then lift it out of the cradle. This video shows how simple it is.
• The ends of the dumbbells are flat. This is thanks to the adjustment mechanism being built into the handle instead of on the end of the dumbbell like with the dial-based adjustable dumbbells. Having flat dumbbell ends makes the dumbbells look and feel more like traditional fixed dumbbells. Importantly, you can balance the dumbbells vertically on your thighs without any discomfort when setting up for exercises like shoulder press or bench press.
• Overall, these are very well balanced dumbbells. As mentioned previously, they’re perfectly balanced between the left and right side at every weight increment. They’re also well balanced between the top and the bottom of the dumbbells, since the adjustment mechanism is completely contained within the center of the dumbbell. This means the plates are just like regular plates; they don’t need notches cut into them for a large handle to be inserted in (i.e. like with the Bowflex/dial-based systems), which would make them somewhat bottom heavy.
• The plates are round except for part of the bottom which is flattened out. This allows you to set them down without them rolling away. But at the same time you still get the traditional dumbbell look of (mostly) round plates.
• Most adjustable dumbbells, especially the selectorized ones, have some amount of rattling. With the Core Fitness adjustable dumbbells, rattling is minimal. I only came across two customer reviews discussing rattling and both said that it was minor. I read some feedback from another customer who said there was no rattling at all even when doing fast movements. If the plates do rattle at all for you, the noise will be dampened thanks to the plastic coating over the plates compared to other sets have cast iron plate shitting into each other.
• The dumbbells have a variable length, meaning they’re shortest at their lightest weight and they become longer as you add more weight.
• The dumbbell length at the lightest setting of 5 lbs (i.e. just the handle) is a mere 9 3/8 inches. The dumbbell length is 14.5 inches at its max weight of 50 lbs. This is impressively compact for adjustable dumbbells. I’d say this is one of the biggest benefits of this dumbbell set, along with the rapid “TwistLock” changing.
• Handle is contoured; thicker in the middle, tapering toward each end. There is a rubberized coating over handle to improve comfort and grip quality.
• Has a 2 year parts warranty

Which Adjustable Dumbbell Set Should You Buy?

1st Place: PowerBlock Pro EXP Stage 3

I believe that the greatest long-term investment is going to be the PowerBlock Pro EXP Stage 3 (or you can buy the Stage 1 set and get the Stage 2 expansion kit and Stage 3 expansion kit later). I believe this so much that I bought them recently. Thus far, they’ve exceeded my expectations.

The PowerBlock EXP dumbbells offer excellent weight expandability up to an impressive 90 pounds. Another major draw is their incredibly fast adjustment. You can go from 5 pounds to 90 pounds in literally just a few seconds.

Plus, their urethane coating makes them more durable and quieter than the Elite 90. Another big positive is that it’s the only heavy PowerBlock set that’s compatible with optional PowerBlock accessories like the straight bar, EZ bar and KettleBlock — all very useful accessories that could add A LOT of additional exercise variety to your training.

Lastly, the Pro EXP adjustable dumbbells are incredibly safe and secure. You don’t have to worry about wear and tear, unlike with the BowFlex SelectTech 1090 dumbbells, as discussed previously. So you can rest assured that what you’re buying won’t fall apart on you and will last a long time.

2nd Place (Tied): PowerBlock Elite 90 OR Ironmaster Quick-Lock Dumbbells

I have a tie for the runner up: It’s the PowerBlock Elite 90 vs. the Ironmaster Quick-Lock Dumbbells.

I gave the Elite 90 set the tied-for-second spot because they have all big, important features of the Pro EXP: 90 lbs max weight, 2.5 lb increments and rapid adjustment. However, they’re louder and less durable since they’re not urethane coated, and they have a closed handle design and lack the v-shaped/wedge cut handle design (less forearm room). Lastly, they’re not compatible with the optional PowerBlock accessories (straight bar, EZ bar, KettleBlock). That said, they are also less expensive than the Pro EXP, which is a plus if your budget is tight.

Whereas, the Ironmaster is a better choice for runner-up if you prefer adjustable dumbbells with a more natural look and feel, and that you can get rough with and toss around a bit without worrying about damaging.

Another major plus of the Ironmaster is the fact they expand up to 120 lbs with the first add-on kit, and then even higher to a whopping 165 pounds with the second add-on kit.

I own the Ironmaster Quick-Lock Dumbbells and love them (though I’m currently storing in my old home gym at my parents house). The main reason why they’re contending for the runner-up spot, and are not #1, is because you can adjust the PowerBlock sets noticeably faster. I know that a lot of people in the market for adjustable dumbbells value adjustment speed very highly. After all, that’s a major draw of adjustable systems.

However, if you’re okay with a moderately fast adjustment time (as opposed to rapid) and you prefer a more robust and natural-feeling dumbbell, then the Ironmasters are for you.
