Short of building your own home gym, there’s an easier (and cheaper) way to match the dynamic offerings of a professional gym. The answer is to invest in the best adjustable dumbbells. Adjustable dumbbells are a versatile piece of home exercise equipment that can accommodate many different strength training exercises. Some sets can replace up to 15 separate pairs of dumbbells, making them a spatially efficient choice for working out at home.

Adjustable dumbbells are great for building muscle and burning calories, and dumbbells are a staple of many weightlifting routines for a reason. And if you’re conjuring images of bodybuilders doing bicep curls, note that you can actually get a great full-body workout with just a set of dumbbells.

What To Look for in the Best Adjustable Dumbbells

There are two types of adjustable dumbbell systems to consider:

  • Automatic dumbbells: These sophisticated weight systems let you change the weight via a rotating dial or a similar mechanism. These systems include Bowflex’s popular SelectTech line of products, which offers a space-saving and cost-effective home weightlifting solution.
  • Manual barbells: The type of adjustable dumbbells most common in gyms, manual barbells require the user to add or remove weights by hand. The weights, usually cast-iron or steel, are kept in place by a barbell collar.

When shopping for dumbbells, you’ll almost certainly need a pair to get a proper workout. Many retailers will sell dumbbells individually, so it’s best to double-check each product description to see if they’re sold as a set or not. You may have to purchase two.

The best adjustable dumbbells for your home gym will depend on your preferences. Are you a heavy lifter? Do you want something aesthetically pleasing? Are you looking for value? In general, the differences between products are subtle, but the main thing to look for is how you want to adjust the weights — automatic or manual — and, if automatic, what type of adjustment mechanism is most appealing — a simple dial, rotating handle or electronic button.

Lastly, most adjustable dumbbells max out around 50 pounds, so we’ve sourced products in that range. Some brands offer lighter or heavier options, so check their other products if you need a different weight.

1. Bowflex SelectTech Dumbbells

Once upon a time, Bowflex was best known for its TV infomercials, but the company has matured into one of the leading makers of premium exercise machines. We’ve written about Bowflex treadmills and spin bikes on Spy recently, but our favorite piece of Bowflex equipment is much more compact: the SelectTech Adjustable Dumbbells. This set of dumbbells is super easy to adjust while you work out. With the twist of the dial, you can select 5 to 52.5 pounds of weight. The dumbbells can be purchased as a single unit or a pair, but we highly recommend the pair.

Pros: Replace your dumbbell rack with a single adjustable dumbbell system. Comfortable grip. Comes with storage rack.

Cons: Much more expensive than manual adjustable dumbbells.

2. NordicTrack 55 Pound Select-a-Weight Dumbbell Pair

These adjustable dumbbells from NordicTrack allow you to choose between 10 and 55 pounds in 5-pound or 2.5-pound increments for a customized workout. They’re made of a combination of steel and hardened plastic for a durable design and are made to deliver the same value as 30 different pairs of dumbbells in the same space. They come with an easy storage tray and can be used alongside trainer-led workouts in NordicTrack’s iFit app.

Pros: Smooth weight selection, durable construction, space-saving alternative, quality fitness brand.

Cons: The springs that allow you to switch between weights can get jammed, so be gentle when using.

3. FLYBIRD Adjustable Dumbbell

For a dumbbell that your whole family can use and can grow with you as your workouts progress, we like the Flybird Adjustable Dumbbell. The dumbbell goes up in five-pound increments between five and 25 pounds. Changing weights is easy thanks to the built-in locking mechanism that holds or releases weights into the accompanying tray. Changing weights takes only seconds, making this an excellent option for HIIT and interval training. An adjustable non-slip handle provides a secure grip. The Flybird tray is only 14.6 inches long and 7.9 inches wide, helping to save workout space.

Pros: Changing weights is fast and easy, includes storage tray, space-saving design.

Cons: The weight is sold as a single unit and not set, which makes this an expensive option.

4. snode Cast Iron Adjustable Dumbbell

If you’re just looking for a single adjustable dumbbell rather than a pair, this option from snode is a great one. It’s got six different gears of adjustable weight ranges from 8 to 50 pounds. The cast iron material is super durable, strong and anti-fall as well. The weight adjustment is super easy, and made to happen at the turn of a dial. The weight has a non-slip handle and the unnotched dumbbell plates on either side ensure an even distribution of weight.

Pros: Durable cast iron material, adjustable weight ranges between 8 and 50 pounds, space-saving.

Cons: Only sold as a single dumbbell, so users who want a pair should consider other options.

5. CAP Barbell 52.5-Pound Adjustable Dumbbell Set

Sometimes the fitness journey is even more rewarding when you can slide each plate on yourself. For those who prefer a more primal weightlifting experience, you can’t go wrong with CAP’s manually adjustable dumbbell set. The cast-iron plates are covered with black epoxy to prevent rust, while the diamond knurled chrome handle offers a sturdy grip. A major perk of the plate-based dumbbells — you can deconstruct and store them neatly when you finish working out.

Pros: Trusted brand. Traditional design. Sturdy build.

Cons: Can have issues fitting certain plates.

6. Nice C Adjustable Dumbbell Barbell

If dumbbells alone won’t get the job done, we suggest this weight set from Nice C. The connector bar lets you transform your pair of dumbbells into a barbell, providing a versatility that’s unmatched on this list. With 12 weight plates, you can lift between 0.6 pounds (the weight of the dumbbell handle) and 33 pounds on the dumbbells, and up to 66 pounds using the barbell function. The Neoprene casing prevents the weights from rolling around and helps you avoid accidents or floor damage where steel plates might not be so forgiving. Instead of sticking to basic curls and flys, the barbell configuration opens up tons of exercises for a dynamic full-body workout.

Pros: Can be converted into a barbell. Neoprene covered to prevent floor damage.

Cons: May not be heavy enough for some if used as a barbell.

7. Yes4All Adjustable Dumbbells

If you’re looking for a set of adjustable dumbbells with a high weight range, check out the Yes4All style. Designed like a traditional adjustable dumbbell, the set comes with two dumbbells that total 105 pounds (52.5 pounds each). Each dumbbell with its 15” handle includes 16 five-pound plates, four 2.5 pound plates, four 1.25 pound plates, and four collar handles. The durable cast iron plates are covered with black paint to help reduce the chance of corrosion or rust. A diamond knurled chrome handle and star-lock collars finish off a set of dumbbells that are safe and comfortable to use.

Pros: Traditional design, made from durable cast iron, including star-lock collars for safety.

Cons: Adjusting weights can be time-consuming.

8. POWERBLOCK Elite EXP Adjustable Dumbbell

Get an entire gym in the palm of your hand with the POWERBLOCK Elite EXP Adjustable Dumbbell. Featuring a weight range of 5 to 50 pounds per weight (similar to the Bowflex SelectTech system), the Elite is sold in a set of two and can grow to 70 and 90 pounds per hand using an extender. An auto-lock feature and two chrome adder weights make it easy to micro-load each dumbbell in increments of 2.5 pounds. Corresponding color bands help to quickly identify weights and the secure magnetic polypropylene pin is rated at 500 pounds for added safety.

Pros: Space-saving, micro-loading increments, can buy weight extenders.

Cons: There’s a learning curve to understanding how to add weights. Not the most attractive design.
