Gone are the days of clunky weight racks.

IF THERE'S one piece of home gym equipment anyone can make room for at home, it's a pair of dumbbells. "There's a reason dumbbells are in every single big-box gym," says MH fitness director Ebenezer Samuel, C.S.C.S., who created an arm-focused muscle-building program, All Out Arms, based heavily around dumbbells. "If you want targeted muscle—and that's what all guys want—then you want dumbbells."

What if you don't have an official home gym or workout area? The great thing about dumbbells is that they require little to no space, especially if you invest in an adjustable pair that can shift from light to heavy with a quick turn of a knob or shift of a setting. Adjustable dumbbells offers a range of weights all in one compact footprint, eliminating the need for multiple sets of weights, and even minimizing the amount of other weight equipment you need. Think about it; just one set can typically replace around 15 standard dumbbells.

They're great at simplifying things by tackling the two main common challenges posed by working out at home: Space and equipment, since most people aren't utilizing an entire rack of dumbbells in their home for workouts (let alone space to accommodate).

To find the best adjustable dumbbells, we tested more than 30 different adjustable dumbbells over the course of the last four years, relying on in-house certified trainers Fitness Director Ebenezer Samuel, C.S.C.S., and Senior Fitness Editor Brett Williams, NASM. (Samuel also utilized the top performing adjustable dumbbells with several of his advanced clients.)

Each dumbbell was rigorously tested in a variety of categories, including durability, weight distribution, and ability to shift between weights efficiently, as well as aesthetics. All dumbbells were tested with three types of exercises: Explosive exercises (like swings and cleans), multi-joint strength exercises (like bench presses and Romanian deadlifts), and accessory motions (like biceps curls and lateral raises). A minimum of 10 sets and 100 reps were performed at both comfortable and near-max weights for each motion. All dumbbells were also dropped from a basic bench to test baseline durability (no adjustable dumbbell should ever be dropped from shoulder height), and all dumbbells were monitored for signs of rust over a three-month period .We also consulted with both our MH Advisory Board, and our Strength in Diversity trainers for deeper anecdotal and experiential thoughts on the best dumbbells.

And if you prefer working out at home, a pair of adjustable dumbbells is a solution that will allow you to take your training to the next level without needing to step foot in a gym. Take a look at our top 9 picks below.

If you’re building the mother of all home gyms and money is no object, this comprehensive premium set of dumbbells from SMRTFT is your man. While testing, our editors noted the set's top-of-the-line construction, crafted from near-bulletproof machined steel that's built to outlast you. The included portable cradles make for easy storage, and the compact design means the entire set takes up far less space than typical fixed-weight dumbbell sets.

The adjustable design means that you can use the same set of weights for every muscle group for a complete full-body workout, and our Men's Health trainers were able to incorporate them into all of their upper body exercise programs in their experience using them. Drop down to a little weight for bent-over flies, for example, or pile on the plates for more intense squats. It all adjusts seamlessly and easily with the built-in selector. Knurled handles make for safer lifting at any weight.

"The Nuobell is the best blend of reliability and authentic dumbbell feel I’ve used. The shape and design of these bells makes them ideal for accessory motions, like skullcrushers and biceps curls, and they’re easy to hold for goblet squats too," explains Samuel, who has been using these for over three years. Aside, from a few scratches, they've held up great to heavy use.

An ultra-sturdy set of dumbbells built for durability, making them perfect for heavy-duty moves like dead stop rows, Romanian deadlifts, and heavy presses.

The Pro 50 Adjustable Dumbbells range in weight from 5 to 50 pounds per bell, which is adjustable in increments of 2.5 pounds. So they’re a good choice for those looking to develop their strength further, especially in accessory movements. The weight adjustment mechanism is also easy to use, with a simple pin system that allows you to adjust the weight swiftly. After testing these for months on end, Samuel feels he's never met a more adjustable dumbbell.

With a length of just 12 inches, these dumbbells take up minimal space in your home gym or workout area, making them an ideal choice for those with limited space. A storage stand is included, too.

They feature a comfortable and ergonomic grip that ensures a secure hold during your workout. The weight plates are outfitted with a patented selector pin, which eliminates the need for any cumbersome knobs or dials.

But, as you may be able to tell by looking at them, they don't offer the same weight distribution as a traditional bell. If you’re looking to use a set of adjustable movements for plenty of accessory movements, go with something more dumbbell-shaped.

Overall, they’re a really durable piece of equipment. Both the weight plates and handle are made from heavy-duty and welded steel, which ensures a long-lasting construction. In fact, over multiple uses testing, we've dropped these from 3-4 feet up after tough sets of presses, and they hold up just fine.

"I love them for farmer's walks, heavy DB lunges, and thrusters, and rely on them anytime I do a metcon-style workout at home," says Samuel.

What do buyers say? "All the Power Block equipment is first rate. Along with the equipment, they have great videos showing you how to exercise," said one buyer on Amazon.

The most innovative dumbbells on the market, the iSelects rely on voice controls to change resistance. That means you can finish a set of bodyweight sit-ups and yell to Alexa to switch to 25-pound dumbbells, then instantly grab your bells to start a set of curls.

They offer a weight range of 10 to 55 pounds per dumbbell, making them suitable for a variety of exercises and fitness levels. The weight can be easily adjusted in 2.5-pound increments, so they’re great for beginners or those looking to build strength conservatively. With a voice-control weight adjustment mechanism, they’re quick and easy to use and minimize interruption between sets.

Another feature we love is the thoughtful design. The dumbbells are shaped to fit the contours of your hand, with a textured grip that ensures a secure and comfortable hold through even your sweatiest lifts. The dumbbells also feature a durable construction with a metal weight plate and a sturdy plastic casing, ensuring that they can withstand regular use and the occasional drop (although you really shouldn't be dropping these tech-heavy guys).

These dumbbells take up minimal space in your home gym or workout area and come with a convenient storage tray that keeps them organized and easily accessible.

They're also compatible with the NordicTrack Select-A-Weight stand (sold separately). The stand allows you to keep your dumbbells organized and at the perfect height for your workout, making it easier to switch between exercises and maintain proper form throughout your workout.

What do buyers say? "I started a new workout routine for the first time in a few years and it requires a lot of dumbbell work. I picked these up and have been nothing but impressed. No issues, changing weight is quick, and they are sturdy. I am a big guy 6"1 220 and have used these regularly for many exercises such as dumbbell push-up rows and haven't had any issues at all. All that said, I haven't installed any app or set it up with a smart device, based on others reviews I don't recommend it as it seems that's when the problems arise," said one Amazon reviewer.

These Bowflex adjustable dumbbells have weights that adjust from 10 to 90 pounds in 5-pound increments, which replaces up to 17 pairs of dumbbells (that's a lot of saved time and money potential). Their weight range also makes them one of the heavier options on the market, suitable for a wide range of accessory movements and heavier exercises.

They're also super easy to adjust; they have easy-to-use selection dials for adjusting weights that are smooth and user-friendly. We find the dial system on these bells to be one of the most user-friendly, satisfying, and reliable mechanisms out of any adjustable dumbbells we've used, with no weights or pin to finick with. But do keep in mind, these require docking each time you adjust.

These bells are also designed with durable molding around the metal plates to protect them from damage and reduce noise during use. The grip handles are also contoured to allow for a natural and solid grip.

One downside: We find the design a bit wide and cumbersome for exercises like curls and even side-loaded squats and lunges. In our experience, they work best for moves like renegade rows and chest-supported rows.

What do buyers say? Out of more than 2,289 reviews on bowflex.com, 98% of buyers would recommend the SelectTech 1090 Dumbbells to a friend.

Yes4All's take on the adjustable dumbbell delivers up to 55 pounds of resistance and anti-rust plates that are built to last.

This dumbbell features a textured chrome handle that provides a grip that feels good during even your most intense sessions. The weight plates are made of cast iron and come in 5-pound increments, ranging from 5 to 52.5 pounds.

To adjust the weight, simply slide the selector pin to the desired weight setting—no complicated docking or technology needed. If you’re not into the new age weight-adjusting tech, this is a good option.

In addition to its uncomplicated adjustment mechanism, this bell has a durable construction that's not going to break on you after some use. The weight plates are coated with a rust-resistant finish to protect them from damage, while the handle is designed to be sturdy and reliable.

What do buyers say? Out of more than 18,305 reviews on Amazon, 89% of buyers recommend the Yes4All Dumbbell Adjustable with at least a 4-star rating.

After using the Bellitron, it's clear we've never met a comparable product with more versatility. You don't just get an adjustable dumbbell with up to 45 pounds of resistance; buy a pair of these, and you can combine them to form a mini-barbell with up to 90 pounds of resistance, too. Even better, the Bellitrons multi-position grips allow you to easily do dumbbell swings and other explosive exercises, too. The brand calls them "the transformer of free weights." When it comes to space-saving home gym equipment, it doesn't get much better.

These are constructed with a sturdy aluminum frame, so you can trust construction won't degrade. Despite their heavy-duty durability, the frame is designed to be lightweight and easy to transport. They feature two handles on either bell that are designed to be comfortable and easy to grip. Each handle is also interchangeable, allowing users to switch between different types of handles depending on the exercise.

"I love doing light presses with the Bellitron, and the base makes it great for plank rows and gorilla rows, too," says Samuel.

These adjustable dumbbells are sold separately. You’ll need to purchase two to access 90 pounds of weight and the convertible barbell.

One thing to note: We wish these could switch weights more quickly between sets; they definitely aren't the bells to use for dropsets.

The Adjustable Dumbbell Set from Core Home Fitness lets you change weights in 5-pound increments, and ranges from 5 to 50 pounds. They also come with a lightweight aluminum cradle for a compact design and easy storage in small spaces.

Weight can be easily adjusted in 5-pound increments using a unique dial system, just with the turn of a knob. These bells are constructed with high-quality materials, including a durable metal handle that's textured to prevent slippage. The weight plates are coated to prevent scratches and reduce noise during use, making them a great choice for home usage.

"I mostly work out in my backyard, but when the elements aren't right or I just want to pump through some curls quickly before going out, I keep these dumbbells ready in my living room for indoor training," says Williams. "They fit under my couch perfectly so they don't add more clutter to the small space, and they're sturdy enough that I don't worry about anything slipping when I adjust the resistance."

The brand offers a limited 2-year warranty on these babies, too, ensuring peace of mind and that the product will last for years to come.

The NordicTrack Select-a-Weight Adjustable Dumbbell Set comes with two dumbbells, each with a weight range of 10 to 55 pounds. Each plate is 2.5 pounds and can be easily adjusted with the brand's unique selector adjustment system and convenient storage trays, replacing 15 sets of dumbbells.

Crafted from a blend of steel and heavy-duty plastic, they feel sturdy and solid in grip.

This set comes with a pair of fitted storage trays, too, each marked with easy-to-read weight identification for plates. Which means these compact weights can stay secure and organized when not in use.

With all the options on the market, it's hard to know how one pair of adjustable dumbbells differs from the next. This isn't a cheap piece of equipment, either, so consider these factors while you shop:

Weight range: Look for a weight range that meets your fitness goals. Most adjustable dumbbells can be adjusted in 2.5-pound or 5-pound increments, so it's important to consider a weight minimum and maximum that fits your needs.

Size and shape: Adjustable dumbbells come in different shapes and sizes. Consider the size and shape of the dumbbells and make sure they feel comfortable in your hands. Basically, does the dumbbell feel "good" or natural to you? Again, this comes down to personal preference and might involve some trial and error.

Adjustability: Some adjustable dumbbells have a dial or pin system that allows you to change the weight quickly and easily. Others may require more time and effort to adjust the weight. Consider which type of adjustment system works best for you. Dial systems tend to be the most user-friendly for beginners.

Weight distribution: Some adjustable dumbbells don't distribute the load only on the outside of the handle, changing how the dumbbell responds to certain movements (particularly accessory movements). A good rule of thumb is if you're looking to perform heavier exercises (farmer's carries, RDLs, rows) you can consider an adjustable dumbbell that doesn't distribute its weight like a traditional dumbbell, such as the PowerBlocks or Stroops Bellitrons. If you're planning to do more accessory movements (like biceps curls or skull crushers), opt for something more dumbbell-like, such as the SMRTFT or Yes4All picks on this list.

Price: Price is important for just about every home gym builder. For many people, this might be the deciding factor. Because a single pair of adjustable dumbbells replace as many as 17 dumbbells, it's important to put this investment in perspective. You want to opt for something that can grow with you in terms of durability and weight range, which the cheapest models often can't.

Warranty: Warranties reflect a manufacturers confidence in their product. And with some of the best adjustable dumbbells priced north of $500, you want to be sure your investment is protected. So, it's important to purchase from a manufacturer that offers a clear, comprehensive warranty. They vary widely across the industry, with the most budget-forward brands offering just 90 days on some parts, and others boasting generous 5-year warranties on everything. Again, the more you spend upfront, the better the warranty is likely to be. And, if there's anything that isn't clear to you about the stated warranty, be sure to ask. It's your money, after all.

Brand and customer reviews: Look for reputable brands with positive customer reviews to understand what experiences buyers have had with the product.

This comes down to three things: Space, personal preference, and how you plan to use your dumbbells.

If you have unlimited space, you can definitely consider standard dumbbells.

"If you're building out a home gym and especially if you like to train accessory motions and work through a full range of motion, you still can't beat standard dumbbells," explains Samuel.

"They're going to be more durable, have better weight distribution for most moves, and, as cool as some adjustment dial might be, there's nothing more efficient than literally putting a 35-pound dumbbell down and picking a 40-pounder up."

But if you're in tight confines or like to workout on-the-go, opt for a good adjustable option. "You can load a pair of Powerblocks in your trunk much more easily than you can load 10 pairs of dumbbells for a road trip."

You'll also want to consider how frequently you'll be dropping your dumbbells. Even the best, most durable adjustable dumbbells on this list still have weight-switching mechanisms and won't hold up to being routinely dropped from a few feet in the air after a set of shoulder presses as well as standard dumbbells.

The basic design of adjustable dumbbells involves a handle that you hold onto during your workout, with a set of weight plates on either end—just like traditional dumbbells. Old-school adjustable dumbbells come with a set of plates of varying weights that can be added or removed from the handle, but newer designs have employed innovative adjustment mechanisms to make adjustable dumbbells more user-friendly.

Dial System: This mechanism uses a dial on the end of the dumbbell handle to adjust the weight. To change the weight, you turn the dial to the desired weight, and the mechanism will lock in the appropriate weight plates. Some adjustable dumbbells must be docked in their storage base to change weight with the use of a dial, while others can be adjusted outside of their docking station.

Pin-and-Lock System: This mechanism uses a pin to select the desired weight, and can take some practice to acclimate to if you're new to it. To change the weight, you pull out the pin, select the desired weight, and then re-insert the pin into the corresponding slot to lock in the weight.

Twist-Lock System: This mechanism uses a twist-locking mechanism to secure the weight plates. To change the weight, you twist the handle to unlock the weight plates, remove or add weight plates, and then twist the handle back to lock in the new weight.

Magnetic System: This mechanism uses magnets to secure the weight plates. To change the weight, you use a tool to detach the weight plates from the handle, remove or add weight plates as desired, and then reattach the weight plates to the handle using the magnets.

Just like standard dumbbells, adjustable dumbbells are safe when used correctly and with proper form. But, as with any type of fitness equipment, there are some safety considerations to keep in mind.

It's important to choose adjustable dumbbells that are well-made and constructed from durable materials. If you're using an old-school model which features removable plates, you should also make sure that they're securely attached to the handle before you start your lift.

The shape, feel, and weight distribution of adjustable dumbbells can take some getting used to, depending on the model you're working with. Because they may feel different compared to standard dumbbells in movements you do regularly, it's important to focus on slow, controlled movements and proper form throughout your workout (especially as you acclimate to them).

Adjustable dumbbells pack a ton of perks compared to regular dumbbells, with the most obvious being their space-saving design: No matter which adjustable dumbbells you choose, you can guarantee they'll take up less space than the sets of traditional dumbbells they replace.

Another attractive benefit of adjustable dumbbells is that they're more cost-effective compared to multiple sets of their traditional predecessors. A lot of the options on this list aren't exactly budget buys, we know. But building out a weight rack with 5-15 sets of high-quality traditional dumbbells can add up in cost even quicker.
