“There’s a reason dumbbells are in every single big-box gym,” says MH fitness director Ebenezer Samuel, C.S.C.S., who created an arm-focused muscle-building program, All Out Arms, based heavily around dumbbells. “If you want targeted muscle—and that’s what all guys want—then you want dumbbells.” Adjustable dumbbells (just like adjustable kettlebells) offer a range of weights from one compact footprint, eliminating the need for multiple sets of weights and even minimizing the amount of other weight equipment you might need. They simplify things by tackling the two main common challenges posed by working out at home: space and equipment. Think about it; just one set of the adjustable dumbbells typically replaces around 15 standard dumbbells.
If you prefer working out at home (or do it out of necessity on days when you can’t make it to the gym), a pair of adjustable dumbbells is a solution that will allow you to be consistent with your training without leaving your abode. Especially when combined with an effective piece of cardio equipment and a great weight bench. Check out our top picks for the best adjustable dumbbells for your home gym in 2025 below.
What to Consider
Weight Range
Look for a weight range that meets your fitness goals. Most adjustable dumbbells can be adjusted in 2.5-pound or 5-pound increments, so it’s important to consider a weight minimum and maximum that fits your needs.
Size and Shape
Adjustable dumbbells come in different shapes and sizes. Consider the size and shape of the dumbbells and make sure they feel comfortable in your hands. Basically, does the dumbbell feel “good” or natural to you? Again, this comes down to personal preference and might involve some trial and error.
Adjustment Mechanism
There are a few different mechanisms that adjustable dumbbells use to switch weights, with some being easier or more pleasing to the user.
Dial System
This mechanism uses a dial on the end of the dumbbell handle to adjust the weight. To change the weight, you turn the dial to the desired weight, and the mechanism will lock in the appropriate weight plates. Some adjustable dumbbells must be docked in their storage base to change weight with the use of a dial, while others can be adjusted outside of their docking station.
Pin-and-Lock System
This mechanism uses a pin to select the desired weight, and can take some practice to acclimate to if you’re new to it. To change the weight, you pull out the pin, select the desired weight, and then re-insert the pin into the corresponding slot to lock in the weight.
Twist-and-Lock System
This mechanism uses a twist-locking mechanism to secure the weight plates. To change the weight, you twist the handle to unlock the weight plates, remove or add weight plates, and then twist the handle back to lock in the new weight
Magnetic System
This mechanism uses magnets to secure the weight plates. To change the weight, you use a tool to detach the weight plates from the handle, remove or add weight plates as desired, and then reattach the weight plates to the handle using the magnets.
Weight Distribution
Some adjustable dumbbells distribute the load differently than traditional dumbbells (atypical), changing how it responds to certain movements (particularly accessory movements). A good rule of thumb is if you’re looking to perform heavier exercises (farmer’s carries, RDLs, rows) you can consider an adjustable dumbbell that doesn’t distribute its weight like a traditional dumbbell, such as the PowerBlock option featured below. If you’re planning to do more accessory movements (like biceps curls or skull crushers), opt for something more dumbbell-like, such as the SMRTFT or Living.Fit picks on this list.
Price
Price is important for just about every home gym builder. For many people, this might be the deciding factor. Because a single pair of adjustable dumbbells replace as many as 17 dumbbells, it’s important to put this investment in perspective. You want to opt for something that can grow with you in terms of durability and weight range, which the cheapest models often can’t.
Warranty
Warranties reflect a manufacturer’s confidence in its product. And with some of the best adjustable dumbbells priced north of $500, you want to be sure your investment is protected. So, it’s important to purchase from a manufacturer that offers a clear, comprehensive warranty. They vary widely across the industry, with the most budget-forward brands offering just 90 days on some parts, and others boasting generous five-year warranties on everything. Again, the more you spend upfront, the better the warranty is likely to be. And, if there’s anything that isn’t clear to you about the stated warranty, be sure to ask. It’s your money, after all.
How We Selected
To find the best adjustable dumbbells, we’ve tested more than 30 different adjustable dumbbells over the past four years, relying on in-house certified trainers including Fitness Director Ebenezer Samuel, C.S.C.S., Senior Fitness Editor Brett Williams, NASM, and Fitness and Commerce Editor Charles Thorp, NASM. Samuel utilized the top performing adjustable dumbbells featured on this list in fitness programs with several of his advanced clients.
We also enlisted the help of Maillard Howell of Dean CrossFit in Brooklyn, NY, to test and assess how well these dumbbells performed in the real world (read: a high-volume, high-traffic training facility). In addition, we sought insights from trainers from both our MH Advisory Board and our Strength in Diversity class for further anecdotal and experiential perspectives on the top adjustable dumbbells.
Each dumbbell was rigorously tested in a variety of categories, including durability, weight distribution, and ability to shift between weights efficiently, as well as aesthetics. All dumbbells were tested with three types of exercises: Explosive exercises (like swings and cleans), multi-joint strength exercises (like bench presses and Romanian deadlifts), and accessory motions (like biceps curls and lateral raises). A minimum of 10 sets and 100 reps were performed at both comfortable and near-max weights for each motion. All dumbbells were also dropped from a basic bench to test baseline durability (no adjustable dumbbell should ever be dropped from shoulder height), and all dumbbells were monitored for signs of rust over a three-month period.
The following four best adjustable dumbbells are what we recommend available today based on all this testing, research, and evaluation.

Best Adjustable Dumbbells Overall
SMRTFT Nüobell 80lb Dumbbells
“The Nüobell is the best blend of reliability and authentic dumbbell feel I’ve used,” says Samuel, who has been using these for over three years. “The shape and design of these ‘bells make them ideal for accessory motions, like skullcrushers and biceps curls, and they’re easy to hold for goblet squats too.” Aside from a few scratches, they’ve held up great to three years of heavy use.
With up to 80 pounds of weight per dumbbell and a feel that’s nearly indistinguishable from traditional ‘bells, users can utilize the same set of weights for a complete full-body workout. Users can quickly drop down to lower weights for exercises like bent-over flies or pile on the plates for more intense squats. “It features a ‘turn-and-click’ design rather than just a built-in selector,” notes Williams. Users simply turn the handle until they reach their desired weight.
During testing, Howell noted that the Nüobell arrived assembled and was easy to plug and play once unboxed. Of all the adjustable dumbbells he tried, these felt the most like actual dumbbells. “These feel like the next evolution of the traditional dumbbells we have become used to in gyms,” Howell said.
The major defining features include: Metal plates and handles, top-tier construction that’s built to handle more volume than we can, the easy click-and-go weight adjustment ability, and the way the weight selected is displayed on the dumbbell itself.
However, Howell expressed some concerns about the rack it came with, feeling it might have been an afterthought. He questioned whether the tempered plastic rack would hold up to constant re-racking of the metal plates over time. Nevertheless, he emphasized that the actual dumbbells are well-crafted and feel solid as hell.
In Howell’s opinion, these dumbbells are best for someone who has invested in a home gym and is serious about fitness. They are tailored for the hardcore client who likely has a squat rack and barbell in their garage as well, but wants to add an elite set of adjustable dumbbells to their training arsenal.
If you’re building the mother of all home gyms and money is no object, this comprehensive premium set of dumbbells from SMRTFT might just be your best pick.

Most Reliable Adjustable Dumbbells
PowerBlocks Pro 50 Adjustable Dumbbells
PowerBlock adjustable dumbbells are an ultra-sturdy set designed for lasting performance, perfect for executing heavy-duty moves like dead stop rows, Romanian deadlifts, and heavy presses. With a length of just 12 inches (including a storage stand), these dumbbells offer decent compactness and versatility.
The Pro 50 Adjustable Dumbbells cover a weight range from 5 to 50 pounds per bell, with adjustments possible in increments of 2.5 pounds. This weight range suits beginners well, and more experienced lifters can expand the weight by opting for additional expansion kits. For those who find 50 pounds per dumbbell insufficient, PowerBlock offers heavier models such as the Elite USA (up to 90 pounds per dumbbell) or the Pro 100 EXP (up to 100 pounds per dumbbell). All models of adjustable dumbbells by the brand feature the same pin-and-lock adjustment mechanism, which is easy to use and avoids jamming issues found in some other systems.
In his testing, Howell pointed out the compact structure of the actual dumbbell, noting the plate-like weights that are more like weighted frames than traditional circular structures. Howell found this design “genius”, as the square nature of the dumbbell makes it easy to lay down once done using it without it rolling away or requiring a rack to rest it in. He also appreciated that they arrived assembled and were fairly easy to unpack and begin using.
However, Howell expressed concerns about the durability of certain components, such as the handles and the “clip” that allows you to lock your chosen weight in, which are made of plastic. He believes these dumbbells might not be robust enough for consistent use, particularly for hardcore gym-goers.
Despite these concerns, Samuel praises their adjustability and durability, stating, “I’ve never encountered a more adjustable dumbbell. I love them for farmer’s walks, heavy DB lunges, and thrusters, and rely on them anytime I do a metcon-style workout at home.” He’s dropped these from three or four feet up after tough sets of presses, “and they hold up just fine.” (Although it’s not advisable to make a habit of dropping any adjustable dumbbells regularly.)
These dumbbells offer a comfortable grip and knurled handles that enhance grip during workouts. However, they do not provide the same weight distribution as traditional bells, as Samuel points out, “If you’re looking to use a set of adjustable movements for plenty of accessory movements, go with something more dumbbell-shaped.”

Best Mid-Range Adjustable Dumbbells
NordicTrack 55 Lb. Select-A-Weight Dumbbells
The NordicTrack Select-A-Weight Dumbbells are sturdy and easy to use, featuring metal plates and a robust plastic casing designed to withstand the occasional drop (though we don’t recommend it). With a weight range of 10 to 55 pounds per dumbbell, adjustable in 2.5-pound increments, they cater especially well to home workouts. However, they’re not our top pick for accessory movements because of the relatively broad plates.
This set arrived assembled and was ready to go once unboxed. “I appreciated that it came with a tray that gave it a home and an easy-to-store footprint,” noted Howell. “Making changes in weight by 2.5-pound increments was fairly easy, and they felt really sturdy and safe even as I adjusted it to the heavier loads—the knurled metal handle helped with this.”
What Howell didn’t love about these was that there was no way to confirm what weight you were using once the ‘bells were removed from the rack. Only the rack is labeled with weight numbers, not the actual dumbbell.
“I think this is an ideal product for someone who knows their way around a gym and is looking for a solid addition to their home to supplement,” says Howell. “They’re perfect for an intermediate client.”
In terms of sound, while “these are quieter than other adjustable dumbbells on the market, they make more noise than the PowerBlocks,” explains Samuel. Additionally, if you wish to incorporate barbell movements into your home workout routine, we’ve found that these dumbbells work seamlessly with the Hyperbell.
For those already invested in the NordicTrack suite of products and utilizing the iFit app in their home gym, these dumbbells offer continuity that makes sense. A tablet/smartphone holder at the back of the cradle facilitates seamless following of virtual workouts.

Best Adjustable Dumbbells For Beginners
REP Fitness Quickdraw Adjustable Dumbbells
Pros
- Compact and straightforward
- Under $300
- Storage base included
Cons
- Only go up to 30 pounds (heavier weights available)
These new REP Fitness Quickdraw adjustable dumbbells are solid and well-made, and coming in at less than $3.00 per pound, their value is hard to beat. Not only do they come at an entry level price point, but they’re also incredibly durable. Steel weight plates and a tough alloy steel handle hold up well to wear and tear from regular use (think rust and scratches).
“One of my favorite equipment makers, I was surprised how long it took REP Fitness to come out with a viable adjustable dumbbell option,” says Thorp. “But it seems like they were waiting to create something special, and that’s what they’ve done with the Quickdraws.”
The plates can be adjusted in 2.5-pound increments, spanning from 5 to 30 pounds. For those heavy lifters, 30 pounds might not be enough, but for the average user looking for a quick pump in the arms or lighter weights for perfect accessory movements, this is a great pick. For anyone who wants to up the weight, REP Fitness does have heavier options available with the same streamlined design.
They’ve patented their Lock-N-Load adjustment system, which is straightforward and allows you to changethe weights simply by fliping a switch on each side of the dumbbell. The ease of this process is no doubt how REP came up with their name. This system allows you to swap the weight quickly, so you need to change the load between dumbbell exercises you aren’t stalled at all.
These dumbbells arrive in two boxes and require minimal assembly upon arrival, which makes them an ultra-accessible choice for delivery and use at home.

What Are the Benefits of Adjustable Dumbbells?
Adjustable dumbbells pack a ton of perks compared to regular dumbbells, with the most obvious being their space-saving design: No matter which adjustable dumbbells you choose, you can guarantee they’ll take up less space than the sets of traditional dumbbells they replace.
Another attractive benefit of adjustable dumbbells is that they’re more cost-effective compared to multiple sets of their traditional predecessors. A lot of the options on this list aren’t exactly budget buys, we know. But building out a weight rack with 5-15 sets of high-quality traditional dumbbells can add up in cost even quicker.
Should You Get Standard or Adjustable Dumbbells?
This comes down to three things: space, personal preference, and how you plan to use your dumbbells.
If you have unlimited space, you can definitely consider standard dumbbells.
“If you’re building out a home gym and especially if you like to train accessory motions and work through a full range of motion, you still can’t beat standard dumbbells,” explains Samuel.
“They’re going to be more durable, have better weight distribution for most moves, and, as cool as some adjustment dial might be, there’s nothing more efficient than literally putting a 35-pound dumbbell down and picking a 40-pounder up.”
But if you’re in tight confines or like to workout on-the-go, opt for a good adjustable option. “You can load a pair of Powerblocks in your trunk much more easily than you can load 10 pairs of dumbbells for a road trip.”
You’ll also want to consider how frequently you’ll be dropping your dumbbells. Even the best, most durable adjustable dumbbells on this list still have weight-switching mechanisms and won’t hold up to being routinely dropped from a few feet in the air after a set of shoulder presses as well as standard dumbbells.
How Heavy Should Adjustable Dumbbells Be?
The weight of adjustable dumbbells boils down to your fitness level and goals. Typically, they come in two main categories: those that max out at around 50 pounds per dumbbell and those that start at 50 pounds and get way heavier.
For beginners and folks looking to engage in moderate strength training at home, a set that maxes out at 50 pounds per dumbbell should suffice. They offer a range of weight that can be used for a wide range of exercises and is a great starting point. Beginners can work on everything from bicep curls to overhead presses to squats with these.
Now, if you’re a seasoned lifter, powerlifter, or someone aiming to build strength, opt for a pair of adjustable dumbbells that can go well above 50 pounds per bell. Adjustable sets like the SMRTFT NÜOBELL Classics offer a max of 80 pounds and 90 pounds per bell, respectively. For experienced lifters, added weight means more versatility to tackle heavy exercises and challenge yourself.
Are Adjustable Dumbbells Safe?
Just like standard dumbbells, adjustable dumbbells are safe when used correctly and with proper form. But, as with any type of fitness equipment, there are some safety considerations to keep in mind.
It’s important to choose adjustable dumbbells that are well-made and constructed from durable materials. If you’re using an old-school model which features removable plates, you should also make sure that they’re securely attached to the handle before you start your lift.
The shape, feel, and weight distribution of adjustable dumbbells can take some getting used to, depending on the model you’re working with. Because they may feel different compared to standard dumbbells in movements you do regularly, it’s important to focus on slow, controlled movements and proper form throughout your workout (especially as you acclimate to them).
