Gym memberships can get expensive, but so can buying equipment to create your own home gym. And when it comes to working out at home, it's often difficult to determine what gear you *actually* need for your fitness routine versus what can be left in the online shopping purgatory of "save for later." But whether you're new to at-home workouts or a seasoned veteran, there is one versatile piece of equipment that'll benefit every kind of athlete: a set of adjustable dumbbells. 

Looking for ways to upgrade your at-home workouts? These are the best adjustable dumbbells you can buy, according to thousands of customer reviews. 

The Best Adjustable Dumbbells of 2021

Benefits of Adjustable Dumbbells

Adjustable dumbbells are the convenient, space-saving alternative to the typical single-weight dumbbells you'd see in the gym. These multi-weight sets have also gone through significant improvements since they first became available and are better than the bulky weights of the past. Instead of precious space being taken up by five pairs of dumbbells in multiple weights (some of which you may rarely use), adjustable dumbbells provide anywhere from five to 50 pounds on a single dumbbell and can reach up to 100 pounds. This allows you to toggle between weights — which you'll likely want to do for different movements or as your fitness level increases — by using just one set. They're also compact and easy to store, making them ideal for at-home exercise when you don't have a ton of space. (Related: Affordable Home Gym Equipment to Complete Any At-Home Workout)

Dumbbells will enhance the intensity of your workout on pretty much any part of the body, from arms and shoulders to legs and core — think weighted squats, lunges, and Russian twists. And weighted exercises like these are not just for those trying to "bulk up." In fact, it's been proven that strength training has a slew of benefits, like burning fat to speed up weight loss, increasing bone density, and, of course, building muscle. 

While some adjustable dumbbell sets are pricey, they're definitely a better value than the gym membership you keep "forgetting" to use (or the price you'd pay to buy separate pairs of dumbbells). Aside from the convenience factor, the best part is that they basically bring the gym to you — so you can get in a great workout without leaving the comfort of your home.

"My husband and I both use these dumbbells," shared a customer. "As a military family who moves every two to three years, it is wonderful to not have to pack up an entire set of dumbbells and keep track of them during the move. My husband and I both have seen awesome results from these. When we change the weight on the dumbbells, it is a nice smooth transition. There is no harsh movement that you might have with other brands."

Best for Quick Weight Changes: Flybird Adjustable Dumbbells

FLYBIRD Adjustable Dumbbells,

Speed demons, take note of this fan-favorite adjustable dumbbell. With five weight options, topping out at 25 pounds, this dumbbell changes weight with just a flick of the wrist. Simply turn the dial to your preferred weight, grab the handle while it's in its rack, rotate the handle, and voilà — you're ready to lift! Plus, the adjustable dumbbell's plates feature a unique lock that prevents the plates from falling off or clanking so loud you can't hear your playlist of workout bops.

One reviewer said: "I begrudgingly got two of these to make a pair of dumbbells because I thought they were taking advantage of the pandemic shortage. What a nice surprise it was to see how high quality they are. They are easy to change, with each turn giving you a nice satisfying ratchet/clicking sound. These aren't bulky like the Bowflex dumbbells, with a notch that makes them super easy to rack on your shoulders. The notch also helps stabilize them for push-ups. So these are worth the price individually!"

Best Durable: Powerblock Adjustable Dumbbells

Best Compact: Nice C Adjustable Dumbbell Weight Pair

These 11-pound weights are a great compact and budget-friendly option for lower-intensity strength training or for those who want to keep their workout equipment unassuming and out of the way. The dumbbells in this easy-to-use set start at 2.2 pounds and go up to 11 pounds each by unscrewing the cap on the end and adding weighted bars inside the dumbbell. All in all, you're able to lift 22 pounds with both dumbbells. While these aren't as heavy as others on the market, they're still more than enough to help tone and strengthen your body and are actually preferable for certain exercises where low-to-moderate weight is recommended. Not to mention, they come in at a fraction of the price of most other dumbbell sets and are super portable.

A reviewer noted: "The design makes it so easy to increase/decrease the weights. I'm really pleased. I've used other adjustable weights which were a PITA to adjust because they involved difficult-to-remove clips etc. I love that I can just twist off the top, pop out (or pop in) the metal bars, and go. More cost-effective than buying a bunch of different weights."

Best for Intermediate Weight Lifters: Soges Adjustable Dumbbell Pair

Coming in hot at 66 pounds total, these adjustable dumbbells are ideal for intermediate lifters. The set comes with four 4.4-pound plates and eight 5.5-pound plates, made from a mixture of iron and sand, so you can increase your weight with ease. You'll also receive a connecting rod to transform your separate dumbbells into one barbell to use while you ease into powerlifting. The standout feature, though, is the plates' octagonal shape, which prevents the dumbbells from rolling away from your workout area — and scratching your hardwood floors — when they're sitting on the ground. Your landlord thanks you in advance. 

"They are compact," said a shopper. "Very nice weights you don't have to worry about them rolling away with the octagon shape. The dumbbells fit great in my hands and I have big hands. The sleeve that joins the two dumbbells together works great and everything stays tight."
