10 Best Adjustable Dumbbells in 2021

Best Adjustable Dumbbells

Dumbbells are an essential part of any home gym. They’re relatively compact, you can use them for training muscles throughout the body, and they’re more affordable than those machines you’ll find on late-night infomercials. The only problem? You have to buy an expensive new set every time you gain strength! That is, unless you have a pair of the best adjustable dumbbells.

With adjustable dumbbells, you can adapt the weight to meet your current fitness level, often down to the precise pound! Determine your desired weight, then add/remove plates until you’ve achieved the perfect level of resistance. Easy, right?

Our favorite adjustable dumbbell comes from ATIVAFIT. Their easy-to-use dumbbell goes up to 55 pounds and features GlideTech technology to make swapping out weights as easy as moving the stopper! Need more weight? We recommend Bowflex’s SelectTech 1090 Dumbbells if you’re looking for adjustable 100-pound dumbbells. But… these aren’t the only great options on our list — keep reading to learn more.

Best Adjustable Dumbbells: A Closer Look

Here’s a detailed look at our favorite adjustable dumbbells.

1. ATIVAFIT Adjustable Dumbbells

The best adjustable dumbbells overall

ATIVAFIT Adjustable Dumbbell

Manufacturer: ATIVAFIT | Weight Range: 5 – 55 Pounds | Adjustment Increments: 5.5 Pounds | Comes w/ Storage: Yes | Warranty: 90-Day | Price: 💰💰💰

If you’re looking for an easy-to-use and ergonomic adjustable dumbbell, you can’t go wrong with ATIVAFIT.

ATIVAFIT’s secret lies with its GlideTech plate system, which makes adjusting the weight from 5 pounds up to 55 pounds a cinch! You simply pull up on the stopper and trace it along the handle until you reach the perfect weight (don’t worry, everything is clearly labeled for your convenience). Let go, and it locks the iron plates into place – snug and secure.

The ATIVAFIT dumbbells boast a slim profile and measure just 8 by 17 inches. And, they come with their own weight tray that doubles as storage!

The only real downside to choosing ATIVAFIT? These dumbbells sell as singles, meaning you have to purchase multiple units if you want a pair. This can be a significant burden, as the price is already fairly high.

  • Ergonomic grip with a soft, textured surface
  • Fantastic space saver for smaller home gyms
  • Easy-to-use plate system featuring GlideTech technology that’s as simple as drag-and-drop

  • Does not come as a set
  • Weight caps at 55 pounds, meaning it’s really only suitable for intermediate lifters

2. Yes4All Adjustable Dumbbells

The best affordable adjustable dumbbells

Yes4All Adjustable Dumbbells

Manufacturer: Yes4All | Weight Range: 9 – 30 Pounds | Adjustment Increments: 5 – 8 Pounds | Comes w/ Storage: No | Warranty: 5-Year | Price: 💰

Say “no” to expensive home gym setups and “yes” to Yes4All’s adjustable dumbbells, the most affordable option on the market.

This no-frills set of dumbbells promises a challenging workout, and boy, does it deliver. It comes with two chrome handlebars and an assortment of 5- and 8-pound iron plates that you can slide on to add more resistance to your training.

Yes, you do have to slide the plates on and off the bar manually, and that can be a pain during conditioning training. But what did you expect for such a bargain price?

If you’re concerned about the quality of this set, don’t be. Yes4All offers an incredible 5-year warranty on all parts, including any additional plates you decide to purchase once you’ve outgrown this set.

  • Sturdy, even with all plates attached
  • Among the best cheap adjustable dumbbells
  • Comfortable diamond-knurled chrome handle

  • QC issues with the star connector

3. CAP Barbell Adjustable Dumbbell Set

The best adjustable dumbbell set

CAP Barbell Adjustable Dumbbell Set

Manufacturer: CAP Barbell | Weight Range: 7.5 – 40 Pounds | Adjustment Increments: 2.5 – 5 Pounds | Comes w/Storage: Yes | Warranty: 30-Day | Price: 💰💰

The CAP Barbell Adjustable Dumbbell Set is an excellent starting point for beginner weight lifters. Their entry-level set comes with two 5-pound steel dumbbell bars, four 2.5-pound iron plates, and four 5-pound iron plates. It also comes with two collars to hold all the weights in place and a storage case for easy stowing.

In terms of poundage, you can divide the weight plates evenly between the pair of dumbbells to hit a maximum of 20 pounds each, or you can attach it all to a single dumbbell for a 35-pound butt-kicking! You can also attach more weight (sold separately) to reach up to 100 pounds per dumbbell. That’s a ton of functionality from one pair of weights!

While it’s a bummer that you have to pay more for weight beyond 40 pounds, it’s understandable when you consider all the features here. Heck, CAP thought of everything with this set, including diamond knurling for superior grip and threaded weight bars for penultimate safety.

  • Top-notch safety features
  • Pristine iron plate casting and overall quality
  • Completely adjustable, as you can add weight up to 100 pounds per dumbbell

  • Some reviewers note that the set weights closer to 38 pounds

As you’ll see, there are several innovative and easy-to-use adjustable dumbbells on this list. But FLYBIRD takes the cake when it comes to overall speed and simplicity.

The process for adjusting the FLYBIRD? You simply place the dumbbell into the storage tray, twist the handle until you reach your desired weight (seen on the visual weight dial), and the locks drop into place. Voila! You’re in business!

While the 25-pound maximum weight isn’t going to get you absolutely ripped, it is perfect for overall conditioning training in your home gym. Use it for curls, rows, or squats, and move through your workout at lightning-speed, adjusting and adapting the resistance as necessary.

  • Fantastic grip
  • Durable aluminum alloy construction
  • You can change the weight in mere seconds

Start at 2.3 pounds with no weights inserted, and go as high as 11.2 with a full loadout — customized to your fitness level.

The Nice C Adjustable Dumbbells are made from grippable TPR and durable neoprene, meaning they’re exceptionally durable and entirely rust-resistant (unlike your standard dumbbells).

  • Fantastic space-saver
  • Easy to use, with a no-slip grip

Worried about finding a pair of dumbbells with enough weight to handle your massive pythons? Relax… Merax has you covered with their Deluxe Adjustable Dumbbells that go up to 71.5 pounds each!

Each dumbbell also boasts an intuitive dial system that works alongside the storage tray to offer finite control over each unit’s weight, down to 5.5-pound increments. How’s the dial system work? With the dumbbell in the storage tray, simply twist the knob on the end of each dumbbell until you find the right level of resistance, lock the dial into place, and you’re good to go. When finished with your set, place the weights back in the storage tray, and take a breather!

The Merax Deluxe Adjustable Dumbbells are the most expensive option on our list, and they’re not for the faint of heart.

Throw in the set’s innovative features like ergo grips and anti-roll plates, and you’ve found yourself the perfect all-in-one home gym setup.

What to Look for in the Best Adjustable Dumbbells

The best adjustable dumbbells offer an affordable, convenient, and gym-quality workout experience from the comfort of your own home.

Think about it. Instead of buying a dozen sets of dumbbell weights, you can simply buy an adjustable “block” of dumbbells. Changing the weight is often as straightforward as turning a knob or sliding a weight pin to select the exact poundage for your fitness level! Quickly change the weight during your workout, and perform dozens of different exercises using the same equipment!

To be sure, adjustable dumbbells are incredibly versatile. In most cases, you can use them for strength training and aerobic conditioning, though some are better suited for one or the other.

Here’s what to look for, depending on your training goals.

1. Strength Training

Strength training, aka pumping iron, involves lifting heavy weight and performing a few reps at a time.

Bodybuilders and anyone interested in putting on some muscle mass will want to buy a set of adjustable dumbbells that reaches upwards of at least 50 pounds per dumbbell. Also, consider a set like the CAP Barbell or YES4ALL, which lets you add additional weights over time. Depending on your current strength, these sets should provide enough wiggle room to level up alongside you as you work for those gains.

When it comes to purchasing adjustable dumbbells for weight training, don’t worry too much about models that offer quick adjustments or minute increments, as you’ll be taking plenty of time to rest between sets. 

That said, do consider options with storage for easy stowing away after use, and try to find a set backed by an extended warranty. Heavier weights are usually more expensive, and you want to find an option that the manufacturer believes in.

2. Aerobic Conditioning

Aerobic dumbbell sets are geared more towards activities like CrossFit and P90X workouts. These workout regimens incorporate a high number of reps at lower weights. The main goal with aerobic conditioning is to increase cardiovascular health and overall endurance, AKA burn fat, sweat a lot, and “get in shape.”

With aerobic training, there is very little time between sets (about 15-30 seconds). That’s because you want to keep your heart rate up to sustain it for the duration of the workout. As such, you’ll want to look for dumbbells that are easy to adjust on the fly. Look for adjustable dumbbells with quick-turn knobs and dial systems, such as the ATIVAFIT or FLYBIRD, which adjust in seconds.

You’ll also want to look out for dumbbells that adjust down to the precise pound, as you’ll need to increase weight slowly as your body gains strength over time. Opt for dumbbells that go up to 20 to 40 pounds each, depending on your strength level and long-term goals.

Sound too heavy? You can always adjust down or choose lighter dumbbells if you’re looking to add a small bit of resistance to exercises like walks or hikes. Sound too light? If you’re jacked and need something capable of keeping up, feel free to take the weight up a notch or two.

Do note that adjustable dumbbells for aerobics are typically smaller and less expensive than their strength-training counterparts, so storage and extended warranties aren’t quite as critical.

Best Adjustable Dumbbell Lifts and Exercises

One of the best things about using dumbbells for strength training is that they are free weights. Free weights are best for maximizing muscle development because they force you to do all the work. A study in the Strength and Conditioning Journal shows that free weights are superior to workout machines. Unlike machine-assisted exercises that keep the weight on a dedicated track, you have to use stabilizing and balancing muscles to help support the weight.

Dumbbells are also more challenging than barbell lifts because you can’t share the weight across both arms. Each arm has to do all the work on its own. This is why, for example, the dumbbell press is much more challenging than the traditional bench press. A person who can max 225 pounds on traditional press will likely only be able to do about 180ish pounds with dumbbells.

That’s why adjustable dumbbells are so incredible — you can adjust them as you grow stronger! Whether you want to tone with high reps and low weight, or build mass with high weight and low reps, you can easily adjust the weight to your liking. 

Adjustable Dumbbell Exercises

Here are some of our favorite exercises to perform using adjustable dumbbells:

  • Dumbbell Press. Just like bench press, dumbbell press is an essential lift for building chest and arm muscles.
  • Dumbbell Incline Press. This exercise is a variation of the dumbbell flat press, but instead, you’re honing upper chest muscles.
  • Dumbbell Shoulder Press. This exercise is performed sitting down, ideally with some form of back support. It works the shoulder and upper chest muscles.
  • Dumbbell Squats. Squats are a core lift of any workout regime. Combine dumbbell squats with lunges, and your legs will be feeling in the next day.
  • Dumbbell Curl. One of the most common dumbbell lifts is the curl. This isolates the bicep and gives it a thorough beating.
  • Dumbbell Tricep Kickback. Along with the dumbbell press, the tricep kickback will help develop the largest arm muscle: the triceps.
  • Dumbbell Kneeling One Arm Row. This is an effective back exercise that is much better than using a machine row.
  • Dumbbell Lateral Raise. The lateral raise is a shoulder exercise that hits the side deltoid muscles. You can also combine this with front raises and shoulder press for a total shoulder workout.
  • Dumbbell Upright Row. Another back exercise, this one hits many of the muscles that the kneeling one arm row misses.
  • Dumbbell Stationary Lunge. One of the most effective leg exercises with dumbbells is the lunge. You can either stay put or (if you have room) walk and alternate legs.
  • Dumbbell Toe Raise. The toe raise is an excellent exercise for working out the calf muscles.
