The 10 Best Adjustable Dumbbells, Tested and Reviewed by Athletes

Adjustable dumbbells offer a consistent, immediate choice between “light” weights for a breezy toning session that totally still counts as movement and a gruelling, grunt-inducing lift where one can actually feel the tiny microtears happening. 

One can adjust based on mood, vibes and actual physical capacity, all within the span of seconds without needing to store ten different dumbbells, which has also made them incredibly popular. Basically, they’re an ideal addition to nearly any home gym setup worth a damn, and SPY is here to help you pick out the best ones. 

They offer the ability to switch between weights seamlessly mid-workout and store all of the equipment for everything from toning sessions to heavyweight training all within one square foot of space. 

Gym people need different things from any given bit of workout equipment, and a great part of adjustable dumbbells is they’ve got flexibility baked right there into the design. Even with that versatility though, everyone has their own preferences. While some might be veteran weight lifters looking to keep their lifting strength up at home, other might only just be stepping into the world of weight training, and that all requires different features and weights.

Why It Stands Out: Bowflex makes easy-to-use and high-quality weights, and this pair of dumbbells is no different. There are plenty of weight increments here to choose from, they’re easy to adjust, and as far as weights go, they don’t look bad either. They’ve got nearly everything anyone needs in a pair of adjustable dumbbells, which is why they sit atop our list of the best adjustable dumbbells. 

Total Weight: 52.5 pounds

Weight Increments: 2.5 pounds up to 25 pounds; 5 pounds after that

Dimensions: 16.0″ L x 8.2″ W x 9″ H (each)

Why It Stands Out: One of the biggest standouts for this pair is the fact that the handles are actually quite comfortable. A lot of adjustable dumbbells use knurled grips, and while that does help grip, it can also shred up palms. These are smoother, and that’s consistent throughout their design as they’re also easy to use, and the stand looks nice. 

Total Weight: 50 pounds

Weight Increments: 5 pounds

Dimensions: 22″ L x 33.5″ W x 31.9″ H

Why It Stands Out: These weights from Ativafit are easy to use, are heavier than Bowflex but with small-enough increments for plenty of options.  They’re an excellent pick for lifting heavier for a cheaper price tag, so if maximization is the name of the game, SPY recommends these. 

Total Weight: Up To 71.5 pounds

Weight Increments: 5.5 pounds

Dimensions: 16.34 x 7.5 x 8.67 inches

Why It Stands Out: For maximum weight with no specific budget, these 1090 dumbbells from Bowflex are the way to go. With almost double the weight of many of the other best adjustable dumbbells, the sheer size of these is the main appeal. Despite their increased bulk, they’re still easy to use and adjust with the same sliding system as Bowflex’s smaller model.

Total Weight: 92.3 pounds

Weight Increments: 5 pounds

Dimensions: 17.5″ L x 9.5″ W x 10″ H (each)

Why It Stands Out: These SMRTFT Nüobells are gorgeous, and their design is only part of their appeal. These weights impressed SPY Editors with their look and usability, as they slide easily in and out of the tray and transitions between weight were seamless. They do have sharp edges, however, so holding each dumbbell by the ends for exercises like halos or dead bugs is uncomfortable.

SMRTFT’s adjustable dumbbells are also designed with more intense knurling, a sharper texture on the handles, that helps you grip but can also be more uncomfortable for the hands. Beginners or those who prefer softer textures should keep this in mind.

Total Weight: 50 or 80 pounds

Weight Increments: 5 pounds

Dimensions: 65 centimeters x 61 centimeters

Why It Stands Out: This is a pair of adjustable dumbbells that isn’t as intent on shredding what’s left of uncalloused hands, and is actually quite comfortable to hold. They still have a grip, but it’s a lot kinder to the skin than the spiky metal of other options on this list. They’re also really easy to adjust via a twist of the handle, which can be a quicker option than knobs or dials. They do have fewer increments than many others on this list though, which is worth keeping in mind. 

Total Weight: 55 pounds

Weight Increments: 11 pounds

Dimensions: 14.6″ L x 7.9″ W x 6.7″ H (each)

Why It Stands Out: Not everyone wants a dumbbell that goes up to 50 pounds, and having a lighter pair is a convenient option for toning and sculpting. These Lifepro adjustable dumbbells are smaller than a lot of the others, and they go up to 15 pounds in 2.5-pound increments. This makes them ideal for newer weight lifters, or even as an additional pair for working on isolations like lateral raises. 

Total Weight: 15 pounds

Weight Increments: 2.5 pounds

Dimensions: 6.8″ L x 8.4″ H x 2.7″ W

Why It Stands Out: An adjustable dumbbell that changes weight using just the sound of your voice? These NordicTrack iSelect Dumbbells will do exactly that, with a good Alexa hub. They’d almost be worth it for the novelty alone, but they’re also very well built and are a solid set of weights without the extra tech appeal. Their design is very clean, and the digital display and adjustment knob feels a lot cleaner and more modern than the other best adjustable dumbbells. 

Total Weight: 50 pounds

Weight Increments: 5 pound

Dimensions: 185 millimeters x 185 millimeters

Why It Stands Out: There’s just something undeniably old-school about the feel of these. There’s nothing wrong with modern designs; innovation drives interest for a reason, but this pair of adjustable dumbbells look like they’ve been ripped from the golden age of weight lifting in a great way. They’ve got an amazing build quality which makes them very durable, and the color-coded weight levels make them easy to adjust between too. 

Total Weight: 50 pounds, with options for 70 and 90 pounds

Weight Increments: 2.5 pounds

Dimensions: 12″ L x 6″ W x 6″ H

Why It Stands Out: Not everyone wants to spend over $100 or more on a pair of dumbbells, even adjustable ones. There are cheaper ones available that are more manual in their design and involve adding and removing weights by hand. They’re not truly adjustable dumbbells in the same way as the others, but they get the job done. 

Total Weight: 50 pounds

Weight Increments: 3 or 7 pounds

Dimensions: 15″ L x 12.5″ W x 4″ H

Are Adjustable Dumbbells Worth It?

While the entry point for any set of adjustable dumbbells, even the cheaper ones, seems high, for those looking to get the same variety of weights as individual dumbbells, while saving space, they’re the only practical option. There’s no denying the convenience they add to any workout, and one could argue they make it easier to progress in strength training by putting that extra five or ten pounds within reach. Testing the waters with a heavier squat or deadlift is not only possible, but encouraged in their streamlined design. With a monetary, space and potential performance benefit — the price tag becomes easier and easier to justify.
