Compare the Best Adjustable Dumbbells of 2025
Bowflex Adjustable Dumbbell
Best Overall
If you’re looking for comprehensive strength training equipment, the Bowflex Adjustable Dumbbells are one of the most popular brands on the market. These adjustable dumbbells come in 15 different weight increments, making them the perfect combination of convenience and versatility. This package also includes a one-year JRNY membership, providing full-body training on-demand through the JRNY app.. The JRNY app comes with motion tracking technology scrutinizing your reps and monitoring your form via your tablet’s camera. The multiple weight options make these adjustable dumbbells ideal for almost all types of users, including beginners, with the weights starting at five pounds up to 52.5 pounds. Using the built-in weight selection dial, you can easily pick the weight that suits your exercise routine and strength level. This product is the best on our list due to its ease of use, compact size, and sturdy construction, which make it perfect for use at home or the gym. Some reviewers did note that the length of the bar is rather long for certain workout movements, and the weights can sometimes “catch” when changing the selection dial.
Yes4All Adjustable Dumbbell
Most Versatile
The Yes4All Adjustable Dumbbell is a single weight that can provide the ultimate home gym experience. It comes with multiple weight options, starting at 40 pounds (20 pounds per pair) and up to 200 pounds (100 pounds per pair), but note that some of these weight ranges would mean you need to buy separate sets. The Yes4All set features durable cast iron plates covered with a black paint finish to ensure the dumbbells are rust and corrosion-resistant. Assembly is a breeze, and a single set can be easily stored. The 14-inch long handle features a diamond-knurled chrome texture to ensure a secure, firm, and non-slip grip. These adjustable dumbbells also come with a star-lock collar designed with loose-resistant rubber trims and screws for a safe, secure workout and easy plate changes. Thanks to the adjustable weights, you can perform even simple body-toning exercises like crunches, squats, and lunges with relative ease.
Nice C Adjustable Dumbbell
Most Unique
The Nice C Adjustable Dumbbells set comes with 12 weight plates and two handles that can each be modified with the plates to create dumbbells or a single barbell. In fact, it’s this unique design that makes these dumbbells perfect for almost performing a wider selection of exercises. Even better, its adjustable design lets you customize the weight of the dumbbell or barbell to suit your fitness level and needs. Besides featuring a neoprene handlebar that provides you with a slip-resistant grip for extra safety during workouts, the set helps you improve coordination and decrease the risk of injury or accident. And, with its two-in-one design, you won’t have to buy multiple sets for different exercises — you can strengthen your upper body, core muscles, and lower body with a single purchase.
CAP Barbell Adjustable Dumbbell
Most User-Friendly
The CAP Barbell Adjustable Dumbbells are an excellent addition to any home gym. This set’s 17-inch handle, star-lock collars, and adjustability make it ideal for working out specific muscle groups or the entire body. It comes with cast iron weight plates that are designed to fit all standards, while the black epoxy finish makes it rust and corrosion-resistant. Even better, it has a medium-depth diamond knurling pattern on its cold-rolled steel handle, which, together with the handle’s length, makes for a stable, strong, and non-slip grip. Meanwhile, because the star-lock collars feature rubber O-rings, they’re easy to tighten and loosen on threaded ends and ensure the weight plates stay securely in place while you work out.

So, we’ve put together a detailed buying guide to ensure you get the perfect adjustable dumbbells.
How to Pick the Right Adjustable Dumbbells
Weight range
When shopping for adjustable dumbbells, it’s important to determine the range of weights you need for your workouts. Some models come with a fixed weight range, while others come with additional weight plates that allow you to increase the weight range to suit your fitness goals. If you’re a beginner, starting with a weight that is too heavy could cause injuries, like muscle strain. Consider what type of exercises you will be doing and pick a weight range accordingly.
Adjustment mechanism
Adjustable dumbbells come with different mechanisms for changing weights. Most will come with one of two options, such as a dial or sliding selector, that allows you to change weights quickly without stopping and starting your workout. You can also consider the locking system. While purchasing adjustable dumbbells, make sure the locking system is both secure and easy to use. Look for sets that require minimal effort when switching weights and offer a locking mechanism that won’t slip out when lifting heavier weights.
Durability
Select an adjustable dumbbell with a heavy-duty construction made of high-quality materials such as stainless steel to ensure longevity. This also ensures you can lift the dumbbell safely without worrying about it falling apart during an exercise session.
Design and ergonomics
Consider the size and shape of the handle when selecting adjustable dumbbells. Look for dumbbells designed with an ergonomic grip so they won’t injure your wrist while lifting.
Size and space requirements
When considering adjustable dumbbells, choose a size that fits your space requirements so they won’t take up too much room when put away. While a smaller-sized adjustable dumbbell set can still offer plenty of versatility and can be conveniently stored, the larger sets provide more weight options but can be trickier to store out of sight.
Handle design
We suggest that any adjustable dumbbell set you are considering comes with rubberized handles and textured grips. These will provide you with a sturdy, secure hold while lifting.
Ease of use
Not all adjustable dumbbell sets are created equal when it comes to swapping out weights. Product reviews from other shoppers can help you determine the level of effort. We suggest looking for a model with easy-to-use knobs or clips that simplify adjusting weight settings.
Maintenance requirements
Unlike basic free weights, some adjustable dumbbells require regular maintenance for optimal performance and safety when working out with them. Before investing in an adjustable dumbbell, read through the instructions to determine any maintenance requirements, such as lubrication or tightening screws, that might be necessary to keep it running smoothly over time.
Tips to Properly Care for Adjustable Dumbbells
Clean them after every use. This will prevent dust build-up, which can cause rusting and a decrease in durability over time.
Store them upright to ensure the stability of the weight plates when not in use and reduce the chances of accidental damage.
Check the tightness of the knobs. You should make sure all knobs remain secure after adjusting weights so they don’t come loose during exercise.
Regularly inspect both the handle and weight plates carefully each time before using them, and address any issues immediately.
Lubricate the dumbbells occasionally — for smooth operation between weight plates, adding lubrication occasionally helps smooth functioning.
