Dumbbells are a great tool to keep in your garage gym or apartment — they’re versatile and they save space. That said, why own 15 separate pairs of dumbbells when you could own one single pair of the best dumbbells that does the same job? Enter, adjustable dumbbells.
When it comes to selecting a pair of adjustable dumbbells, however, there are a few things to consider. How much money are you willing to spend? How much weight do you need or want in each bell? What are the pros and cons of adjustable dumbbells? And what’s your overall skill level in the gym? Our team of experts, including personal trainers and athletes, tested more than a dozen products to find the best adjustable dumbbells on the market.

Check out our full video review of the year’s best adjustable dumbbells. Watch as BarBend expert reviewer Jake Herod talks through each top pick and outlines what these weights can bring to your at-home setup.
Best Adjustable Dumbbells Overall: NÜOBELL Adjustable Dumbbells
This Swedish-designed “smart” dumbbell adjusts from 5 pounds up to 80 pounds — all you have to do is twist the handlebar. Its sleek, modern design will make a great addition to any home gym.
Specs
- Available Weight: 5 to 80 pounds in 5-pound increments
- Shape: Round
- Plate Material: Steel
- Replaces: 16 pairs of dumbbells
- Grip: Knurled handle
- Adjustment Mechanism: Dial
- Warranty: Four years for product defects
- Price Per Pair: $780
Why We Like It
This Swedish-designed “smart” NÜOBELL dumbbell has a twisting handle that changes weight in increments of five with ease, making for a sleek addition to any home gym set-up. Plus, it looks sharp, and the steel plates are extremely durable. After taking the NÜOBELL through many bench presses, rows, lat raises, curls, goblet squats, and Romanian deadlifts, our testers gave these a 5 out of 5 for overall experience.
While many other brands use slide or quick-lock systems to switch between weights on their adjustable dumbbells, the NÜOBELL uses a twisting handle system — simply twist the handle to the number you want, pick up the weight, and you’re good to go.
“It’s super easy to adjust the weight,” according to Jake Herod, BarBend’s expert product tester, who gave the adjustability a 5 out of 5. “A lot of times, with adjustable they get stuck on you … that’s something I haven’t experienced with these dumbbells and I don’t think you will either.”
Want to see these weights in action? Watch our tester give these adjustable dumbbells a try.
The weight range here is wide, as well, going all the way from 5 pounds up to a maximum weight of 80 pounds, which earned the weight range a 5 out of 5. “The passive volcano style knurling provides plenty of grip with little slipping in use,” our tester said, rating the knurling a 4 out of 5. “The only issue is that chalk may stick to the black zinc handle.” This isn’t a huge problem but some may not love that factor for aesthetics.
Aside from functionality, this piece of equipment looks both simple and sleek, making it a great (and aesthetically pleasing) addition to any home gym space. And each weight only takes up as much space as a shoe box, our tester says. So, they’re definitely among the best compact exercise equipment money can buy.
Unfortunately, these are a little pricey at $780, earning a 3.5 out of 5 for overall value. This may not fall in every athlete’s budget and there are cheaper options. However, for the weight range you get with this set, we definitely recommend this product if it’s in your price range. The brand also offers a four-year warranty for product defects, though it doesn’t cover normal wear and tear. Nevertheless, we like the extended years of coverage.

Best Durable Adjustable Dumbbells: REP QuickDraw Adjustable Dumbbells
These REP Fitness adjustable dumbbells are extremely user friendly, as the adjustable mechanism is simple and easy to use. Plus, these are relatively inexpensive compared to other products.
Specs
- Available Weight: 5 to 30 pounds, 5 to 40 pounds, 5 to 50 pounds, 5 to 60 pounds all in 2.5- or 5-pound increments
- Shape: Round
- Plate Material: Cast iron and steel
- Replaces: Up to 18 pairs of dumbbells
- Grip: Knurled handle
- Adjustment Mechanism: Lock-N-Load switch
- Warranty: Lifetime
- Price Per Pair: Starting at $335.99
Why We Like It
For those who want an easy-to-use pair of adjustable weights, the REP QuickDraw Adjustable Dumbbells are durable, extremely intuitive, and simple to adjust. “These weights are incredibly easy to change,” our tester says, giving the overall experience a 5 out of 5. “They click when adjusted, so you get an audible confirmation you’re ready to lift. These are by far among the fastest-adjusting sets we’ve tested.”
Alongside the user-friendly appeal, REP’s weights are sturdy and well-crafted, earning a 4.5 out of 5 for durability. “These weights are tanks,” our tester said. “These dumbbells are super strong and can withstand being thrown or dropped easily. One of the best features is their durability.”
These have volcano-style knurling that feels really nice, our tester said, giving this factor a 4 out of 5. We didn’t notice any tears even after dynamic exercises like snatches, which is a plus. “I’d compare the knurling to a Rogue Echo bar but even more passive, so it works for a variety of athletes,” our tester said.
Unlike some other adjustable dumbbells, these come with two add-on plates that are separate from the cradled weights. These allow you to add on smaller increments to your lifts, though this does slow down the adjusting process a smidge, which may not be ideal for some HIIT workouts.
For overall value, our team gave these a 4.5 out of 5. In terms of quality and adjustment mechanism, they’re comparable to the NÜOBELL but you do have more price point options, which we like. These weights start at $335.99 for the five to 30-pound pair and go up to $499.99 for the 5-to-60-pound pair.

Most Versatile Adjustable Dumbbells: NordicTrack Select-A-Weight Dumbbell
These adjustable dumbbells replace 15 pairs of dumbbells with a top weight of 55 pounds, and feature steel handles that are knurled to assist your grip.
Specs
- Available Weight: 5 to 55 pounds in 2.5- and 5-pound increments
- Shape: Round
- Plate Material: Plastic and steel
- Replaces: 15 pairs of dumbbells
- Grip: Passive knurled handle
- Adjustment Mechanism: Weight-pin selectors
- Warranty: N/A
- Price Per Pair: $399
Why We Like It
Dumbbells that offer small weight increases allow you to do a wider variety of movements. If you’re an athlete who wants to do dumbbell presses and rear delt flyes with the same set, these Nordictrack dumbbells should be your go-to. Given the versatility of these smaller increments, our team gave the optionality with these dumbbells a 5 out of 5.
These weights are sturdy and well-balanced however they do have some plastic components, so we gave them a 4 out of 5 for durability. The steel handle has moderate knurling, so they feel secure in your hand, according to our tester, earning a 4 out of 5 for knurling. “The knurling is passive, so it won’t feel rough on your hands and they’re great for any gymgoer who likes a secure grip,” our tester said.
Unfortunately, the adjustment mechanism isn’t quite as simple as you might find with the NÜOBELL, for instance. You need to slide weight pin selectors to find your ideal resistance level. It doesn’t take super long but may not be ideal for quick-paced HIIT workouts, so we gave these adjustable dumbbells a 4 out of 5 in use.
Watch our tester Jake Herod try out the NordicTrack Select-A-Weight Dumbbells himself.
Despite the slightly more tedious adjustment mechanism, we still think these are a great product for the budget-friendly price. We gave these NordicTrack dumbbells a 5 out of 5 for value, as the $399 price point is cheaper than many other products on the market.

Best Loadable Adjustable Dumbbells: Titan Fitness Loadable Dumbbell Handles
If you already own a plethora of weight plates, these Titan Fitness Loadable Dumbbells can be an excellent choice for your setup. The 6.5-inch loadable sleeves can house multiple plates at once up to 400 pounds, and the full knurling across the 28-millimeter handle provides a sturdy, controllable grip that’s ideal for those heavy presses and pulls. Up to 50% off early holiday deals.
Specs
- Available Weight: 400-pound capacity
- Shape: Round
- Plate Material: Iron
- Replaces: N/A
- Grip: Knurled handle
- Adjustment Mechanism: Plate-loaded
- Warranty: One year
- Price Per Pair: Starting at $125.99
Why We Like It
Loadable dumbbells are an excellent choice for those who have space to spare and want a truly customized lifting experience. These Titan Fitness dumbbell handles are loadable, so you can stack your own plates onto either side up to 400 pounds. Overall, our team gave these a 4 out of 5, as the options are pretty endless. You can also buy additional plates for heavier lifts.
I personally own these dumbbells and have been using them in my own training and with my personal training clients. The plates are easy to load but I definitely recommend using spring clips, as the collars take up a lot of space on the loadable sleeve.
When it comes to durability, don’t expect these to break down any time soon. They’re made of iron with a chrome finish, so they’re plenty durable. However, I did have to give this category a 4.5 out of 5, as I have noticed a little bit of corrosion after a few years sitting in a non-climate-controlled garage gym.
The handles have a diamond knurling on them but it’s pretty passive. These are easy to grip but won’t tear apart your hands. Overall, I rate the handles a 4 out of 5. They’re not the best grip but get the job done.
For overall value, we gave these a 5 out of 5. They’re definitely cheaper than the non-loadable adjustable dumbbells and they go higher in weight. Plus, we actually like that you can buy separate plates. Pro tip: Read specs carefully before you buy plates. These only accommodate Olympic-sized plates.

Best Value Adjustable Dumbbells: FLYBIRD Adjustable Weights Dumbbells
These budget-friendly adjustable dumbbells use five-pound weight increments to replace five pairs of dumbbells. The rotating dial allows quick adjustment between 5 and 25 pounds.
Specs
- Available Weight: 5 to 25 pounds in 5-pound increments
- Shape: Round
- Plate Material: Plastic
- Replaces: Five pairs of dumbbells
- Grip: Silicone-coated handle
- Adjustment Mechanism: Dial
- Warranty: One year
- Price Per Pair: $99 per dumbbell
Why We Like It
One reason why dumbbells can be so expensive? You need to buy two of them! But there are plenty of single-dumbbell exercises you can do to gain strength. Our favorite value adjustable dumbbell is this option from FLYBIRD, as they’re sold by the weight at only $99.
FLYBIRD’s single dumbbell replaces five sets of weights with a 5-, 10-, 15-, 20-, and 25-pound option. To select the weight, you grip the non-slip handle and turn it to the dial’s corresponding number. “These are easy to use and change up,” according to our tester who gave this weight an overall 4 out of 5 in use. “You can hear the weight click into place. I do think the tray felt a little flimsy, though, as it’s just plastic.”
We did have to give these a 2.5 out of 5 for optionality, though. This weight only goes up to 25 pounds, which can be too light for many athletes. You also only get five-pound increments, so you can’t make tiny jumps in weight as with a two and a half-pound increment option.
“I have to question the durability just because there’s a lot of plastic on this weight,” our tester said, giving the durability a 2.5 out of 5. “The weight plates also seem to move a little as if they’re not totally secure. They won’t necessarily break but I wouldn’t drop this weight.”
For value, though, this weight is definitely budget-friendly. One dumbbell is $99, so even if you bought two to create a pair, it’s still cheaper than most other options on the market. “This weight won’t last decades but if you want a simple weight for occasional at-home workouts, it would do the trick,” our tester said.

Best Adjustable Dumbbells for Heavy Lifting: Ironmaster Quick-Lock Adjustable Dumbbells
These quick-lock adjustable dumbbells go up to 75 pounds and feel like a real dumbbell when used. They're heavy duty but you do also get a lifetime warranty in case you experience any damage.
Specs
- Available Weight: 5 to 75 pounds in 2.5-pound increments
- Shape: Square
- Plate Material: Iron and chrome finish
- Replaces: N/A
- Grip: Knurled handle
- Adjustment Mechanism: Quick-lock dial
- Warranty: Lifetime
- Price Per Pair: $698
Why We Like It
For more advanced athletes, a standard adjustable dumbbell just won’t cut it. If you’re looking for a little more weight capacity per dumbbell, we recommend Ironmaster Quick-Lock Adjustable Dumbbells.
We think these adjustable dumbbells tick a lot of boxes and would give them an overall 3.75 out of 5 rating. Not only do they have a high weight capacity per dumbbell, they also offer add-on kits that bring each individual weight up to 120 or 165 pounds.
However, we do think the dumbbell design isn’t as convenient as some of the other dial systems. Like a loadable dumbbell, you need to add on plates to either side of the dumbbells in order to adjust. And since these are square, thin plates specific to the brand, you can’t just stack on any weight of choice.
For durability, we did think these were a solid choice, rating this category a 5 out of 5. These dumbbells are made of iron with a chrome finish, making them more durable than some of the other dial-adjust picks on this list. They also have zero plastic components and are totally safe to drop.
These aren’t the priciest weights on this list, nor are they the most budget-friendly. This set runs you about $698. However, we did give the value a 4.5 out of 5, as other picks around the same weight tend to be more pricey.

Best Adjustable Dumbbells for Small Spaces: PowerBlock Pro 100 EXP Dumbbells
These iconic adjustable dumbbells from PowerBlock can be great for athletes training in tight quarters, as they can replace up to 30 fixed dumbbells in a singular silhouette. Thanks to their compact seating across the design, there’s little room or plate wobble once you get these dumbbells in motion for a more secure and durable setup.
Specs
- Available Weight: 40 to 100 pounds
- Shape: Square
- Plate Material: Cast iron
- Replaces: 30 pairs of dumbbells
- Grip: Option of ergonomic TPR or straight knurled handle
- Adjustment Mechanism: Selector pin
- Warranty: Five year
- Price Per Pair: Starting at $539
Why We Like It
Not everyone’s home gym has ample space for dozens of dumbbells. That doesn’t mean you need to sacrifice your progress, though. PowerBlock’s adjustable dumbbells go up to 100 pounds each, replacing 30 pairs of dumbbells with only two shoe-box-sized weights.
Overall, our team thought these adjustable dumbbells deserved a 4 out of 5. Not only do they replace dozens of individual pairs, they’re easy to adjust, thanks to the magnetic selector pin. They also come with 2.5-pound increments or 5-pound increments, making it easy to progress at your own pace.
You can choose from two different handle styles, either knurled or TPR (thermoplastic rubber). TPR handles are generally a little more squishy and soft in your hand, compared to standard knurling.
These are built with iron and black urethane, making them durable for standard use. However, our testers did give the durability category a 3.5 out of 5. The PowerBlock adjustable dumbbells do have some plastic components, so you don’t want to be dropping them on the ground.
When it comes to overall value, we rated these weights a 4 out of 5. They do have the capacity to replace a huge number of individual dumbbells, plus they are a space-friendly size. These aren’t the cheapest option on the list but if you’re tight on space in your garage gym, they’re worth the investment.

Best Quick-Change Adjustable Dumbbells: Snode 80lb Drop-Proof Dumbbells
These adjustable dumbbells offer weights ranging from 10 pounds to 80 pounds in 10-pound increments and are almost entirely made from metal.
Specs
- Available Weight: 10 to 80 pounds in 10-pound increments
- Shape: Round
- Plate Material: Cast iron
- Replaces: Eight pairs of dumbbells
- Grip: Knurled handle
- Adjustment Mechanism: Dial
- Warranty: Two years
- Price Per Pair: $805
Why We Like It
For those who love to perform drop sets or super sets, a quick-changing dumbbell is a must-have. That’s where the Snode 80-Pound Drop-Proof Dumbbells come in. These have an easy-adjust system where all you have to do is turn the handle in the dumbbell cradle to add on or take off weight plates.
Most adjustable dumbbells don’t go up to 80 pounds but these are also ideal for heavy lifters. Unfortunately, these only adjust in 10-pound increments, so we had to give the optionality a 4 out of 5. But if you love to focus on big compound weightlifting movements, they’re a solid pick.
Considering heavy lifters may need to drop their weights every-so-often, these Snode dumbbells fit the bill. These earned a 5 out of 5 for durability and are the only adjustable dumbbells we’ve tested that are protected against drops up to 32 inches (about two and a half feet) from the ground. “Most other adjustable dumbbells actually recommend against dropping their weights entirely,” our tester said.
These handles are 36 millimeters, which is actually a little thicker than most adjustable dumbbells. This is ideal for heavy lifters, as it can provide a better grip on the weights (and maybe even a forearm pump). We gave the knurling a 4 out of 5, as it’s secure enough to minimize slipping but relatively standard.
As mentioned, the adjustment mechanism is pretty simple to use. All you have to do is twist the weights to adjust to your desired weight. However, these are pretty pricey. They cost almost the same as the NÜOBELL but they don’t have as many weight options, so we had to give the value a 4 out of 5.
These have 10-pound increment increases, which may work great for some athletes. But for others, these increments may be a little too big, especially if you’re working to increase your PR on a challenging exercise.

Best Adjustable Dumbbell for Beginners: BowFlex Results Series 552 SelectTech Dumbbells

How We Tested and Chose the Best Adjustable Dumbbells
Since these adjustable free weights have different forms and functions, there are several key factors to examine when purchasing. Our team of experts tested more than a dozen options to fully explore the pros and cons of adjustable dumbbells while crafting this list. Using our BarBend equipment testing methodology, here are the factors we considered while evaluating each adjustable dumbbell pick.
- Ease of Use: Adjustable dumbbells can be a little tricky to use, as they have several moving pieces that can get stuck, jammed, or out of line. We considered the changing mechanism on each set to evaluate the ease of use and durability.
- Dumbbell Style: Adjustable dumbbells come in all shapes and sizes, some of which are not so convenient. Luckily, today, round adjustable dumbbells (which feel like a standard dumbbell) are more common, according to Amanda Capritto, CPT, CF-L1, CES, CSNC. So, we prioritized shapes that were easy to maneuver and lift.
- Weight Range: Different adjustable weights offer different weight ranges, so our team tried to provide a variety that’s suitable for athletes of all levels.
- Increments: Some adjustable dumbbells have smaller gaps between weights (like two and a half pounds), whereas others jump in larger increments of five or ten pounds. We tested sets with a variety of increment options.
- Durability: Unfortunately, adjustable dumbbells aren’t as resilient as standard weights. Our testers selected products that are as durable as possible, taking them through several workouts and, in some cases, drop tests.
Benefits of Adjustable Dumbbells
Adjustable dumbbells are a great idea for a lot of reasons. Primarily, they save a ton of space in your home compared to a full set of traditional dumbbells. But they also make it much easier to switch weights during a workout, and, while a pair can be expensive, they can actually save you money versus buying a whole rack of weights. Here’s a closer look at the pros and cons of adjustable dumbbells.
- Space Saving: A single pair of adjustable dumbbells is usually about the size of two shoe boxes sitting side by side. If you’ve got an entire room or a garage as a workout space, standard dumbbell sets can work, but even then, adjustable dumbbells can free up that room for a treadmill or a plyo box or two.
- Ease of Use: Every lifter knows the irritation of lugging one set of dumbbells back to the rack to swap weights. With adjustable dumbbells, you can swap your weights out with a twist of a knob.
- Cost-Effectiveness: This might sound counterintuitive when you look at some of the prices here, but $400 for a set of adjustable dumbbells isn’t that bad when you consider that a full set of 5- to 50-pound dumbbells can cost $1,000 or more. “Adjustable dumbbells offer all the same fitness benefits as fixed dumbbells but with the added benefit that they can be less expensive than a set of fixed dumbbells and they take up less space,” Amanda Capritto, CPT, CF-L1, CES, CSNC says.
- Building Strength: Although some trainers or athletes may suggest lifting free weights are more effective at building muscle than machines, that may not necessarily be the case. (1) After testing one against the other, researchers have found that free weights (like adjustable dumbbells) and weight machines build strength similarly.
What to Consider Before Buying Adjustable Dumbbells
Before you buy a pair of adjustable dumbbells, read through all the factors worth considering to find your perfect pair.
Fitness Level
Your training experience can be a major indicator of which adjustable dumbbell is right for your needs. If you’re a beginner athlete just getting started in resistance training, you’ll likely not need a massive dumbbell profile filled with heavier weights. On the contrary, more experienced strength athletes or stronger individuals may need the heavier totals in order to effectively perform their favorite dumbbell exercises. Think about your skill set and capabilities and go from there.
Training Goals
Similar to your fitness level, you’ll also need to consider your end goals when it comes to training. For example, if your aspirations are more cardio-based like completing a marathon or logging a personal best cycling time, it may be more logical to purchase one of the best treadmills or exercise bikes prior to a set of adjustable dumbbells.
Weight Range and Weight Increments
A set of adjustable dumbbells isn’t going to do you any good if they don’t weigh enough. The tricky thing is, while max weights can vary, many of these dumbbells have similar dimensions. It’s not like with traditional dumbbells, where you can eyeball the weights and pick the bigger ones.
“It’s ideal to choose a pair that has a maximum weight that’s more than you can currently lift, so you can progressively overload with them,” Amanda Capritto, CPT, CF-L1, CES, CSNC recommends. Read the specs carefully, and pick a set of dumbbells that maxes out at 10 to 20 pounds above your top weight, if possible. That way, you still have some room to grow with them.
Weight increments are also a key factor when choosing adjustable dumbbells. Most weights go up in 5- to 10-pound increments, although some do offer smaller weight changes and micro-adjustments closer to 2.5 pounds. These can be excellent for smaller shifts in working totals, but can begin to add extra plates creating a large dumbbell silhouette, overall. In the end, look for an adjustable dumbbell setup that features accommodating weight increments to your training style.
Beginner lifters may want to look for adjustable dumbbells that range from 5 to 50 pounds, ideally with smaller weight increments to adjust for finer weight changes. Strength-focused lifters who are looking for dumbbells for heavy lifting can probably be fine with larger 10-pound increments, but they may need a higher max weight — anywhere from 80 to 120 pounds or more.
Adjustment Mechanism
How quick do you want to make changes to the weights on your adjustable dumbbells? The type of adjustments on your adjustable dumbbells is an important factor, then.
The fastest adjustment speed is usually from dial systems, where a quick turn of a knob or the handle adjusts the weight up or down. You can usually adjust these dumbbells from the lightest to the heaviest increments in just a few seconds. Selector pins can also be quick, but usually have multiple pins to adjust. This, at times, can be a little clunky, which may slow you down a bit.
Loadable dumbbells will be the slowest adjustment to make, since you’re adding or replacing weight plates onto the dumbbell’s sleeves. However, you can potentially go heaviest with these types of adjustable dumbbells: You can loads them with whatever weights fit on the loadable sleeve. These dumbbells won’t have a flat end like normal fixed dumbbells; for a more traditional look and feel, you can use spinlock dumbbells, which will have a flat end at any weight.
Materials
Your adjustable dumbbell’s materials are highly influential on the sturdiness and resiliency of the training tools. Metals like steel, cast, and iron can be more resistant to wear and tear than cheaper plastics and can better withstand the errant drop or roll during sessions. As far as adjustment mechanisms, you’ll likely find these moving parts constructed from lightweight plastic or nylon.
As with other fitness equipment, materials used can dictate price, so be sure to look for adjustable dumbbells constructed from high-quality resources while still remaining affordable.
Durability
Even if you’re not one of those athletes that drops weights from overhead (don’t, by the way), there’s still a chance that you’ll drop a dumbbell every now and then. And if you manage to break a weight plate or the adjustment mechanism when you do, you’ve just flushed a few hundred dollars down the drain.
“Steel models will naturally be more durable, but plastic models have also lasted the test of time,” Capritto says. “As long as you don’t drop them or throw them around (please don’t), you shouldn’t run into too many issues with durability.”
Warranty
It can be wise to seek out adjustable dumbbells with some available warranty coverage to plan against any potential defects or required repairs. Let’s face it — strength training equipment gets put through the wringer regardless of how careful you are during your workouts. A well-rounded warranty can help alleviate future expenses and provide some peace of mind that your investment isn’t ill-protected.
Price
Of course, no dumbbells will do you any good if you can’t afford them. Figure out what you’re willing to spend, then stick as close to that budget as you can.
The price per pound is easy to figure out on a fixed dumbbell set, but less so on adjustable dumbbells, since you’re buying two dumbbells that can replace a dozen dumbbells or more. Generally speaking, most dumbbells that go to around 50 pounds will cost between $400 and $600, while heavier adjustable dumbbells are about $800 or more, depending on how heavy they actually go.
Because they replace multiple dumbbells, you’re typically saving with adjustable dumbbells, although the initial price can seem steep at first.

Adjustable Dumbbells vs. Fixed Dumbbells
So, what are the pros and cons of adjustable dumbbells versus fixed dumbbells? Fixed dumbbells are what you see at most big box gyms. They have iron handles with knurling (most of the time) and rubber-coated bells at either end. Your favorite CrossFitter is probably repping out cleans and snatches with rubber hexagonal dumbbells. If you’ve seen Mat Fraser’s home gym, he has a wall full of these dumbbells. Literally.
Compared to adjustable dumbbells, the fixed variety is typically more durable and is available in more weight. Durability is important if you’re swinging and snatching the bell overhead. The components of fixed dumbbells are also far more cohesive than adjustable dumbbells.
An adjustable dumbbell often has loose plates that connect and disconnect to the handle (which makes them adjustable). But as a result, the dumbbell isn’t as sturdy. By comparison, the fixed dumbbell is welded to the weight, so it feels more solid in your hand.
Adjustable dumbbells are both cost-effective and space-efficient. For example, to own all of the weights that the NordicTrack adjustable dumbbell offers, you’d pay hundreds of dollars. NordicTrack costs about half as much and fits neatly in the corner of a room. The space and money you save are, far and away, the best aspects of owning adjustable dumbbells.
How Do Adjustable Dumbbells Work?
Adjustable dumbbells work by engaging and disengaging a range of weighted plates across a given sleeve of the dumbbell profile. Similar to the best adjustable kettlebells, you choose your working weight, toggle the adjustment mechanism to that metric, and remove the dumbbell from a rack or resting position. The engaged weights stay attached to the handle and fixture, while the unused weight plates remain in the rack.
In terms of the locking mechanisms, themselves, many of today’s adjustable dumbbells employ a dial-style or turn-style system that has you, as the names suggest, turn a dial or the handle itself in order to reach your desired working weight. Some silhouettes do use a lock-and-pinion setup, like the PowerBlock Pro Adjustable Dumbbell, that uses a physical key to separate the plates prior to training.
Additionally, you can find loadable dumbbells that are an adjustable profile, as well. However, you can more efficiently think of these as miniature versions of the best barbells in that you’ll need additional change plates to create your weight totals and barbell collars are needed to hold the plates in place during movement.
Types of Adjustable Dumbbells
Adjustable dumbbells can be a general term applying to any dumbbell profile that can operate at multiple weights in a single silhouette. The locking mechanisms, plate shapes, and materials can vary from one dumbbell to the next, but the general “type” stays consistent.
That said, though, loadable dumbbells are slightly different in that you’ll need extra weight plates to create your working totals. This adjustable dumbbell type can be great for home gyms that already have an abundance of change plates, but may not be ideal for those trying to train in apartments or those that don’t have a ton of training equipment.
Safety and Maintenance of Adjustable Dumbbells
To get the most out of your adjustable dumbbells (or any fitness equipment), it’s important to care for and maintain them. While maintaining your adjustable dumbbells isn’t difficult, there are a few things to keep in mind to have your adjustable dumbbells operating in the best possible condition for years to come.
The most important thing for both the dumbbell’s longevity and the safety of your home gym is to avoid dropping your dumbbells. Many adjustable dumbbells have a lot of moving parts, and a dumbbell hitting the ground at an awkward angle can be enough to break those mechanisms.
Even with a few adjustable dumbbells having a warranty that covers drops, I’d still recommend to avoid dropping them when possible. While the impact may not damage those dumbbells, it can still cause damage to your gym floor — or you, if the dumbbell lands right.
Here are a couple of things to do to help maintain your adjustable dumbbells:
- Regularly check the dumbbell’s selector pins, dials, and other moving parts for any looseness, cracks, or breaks in the equipment. If your dumbbells are still under warranty, notify customer service.
- Store the adjustable dumbbells in the proper trays or stands when not in use. Leaving them in an awkward position can put unneeded stress on certain parts of the dumbbell, so putting them in the dumbbell trays will help avoid unnecessary wear on those components.
- Clean the handles as needed. Brush off any chalk after use, and wipe the handles with a mild cleaner. Avoid getting any water in the mechanisms.

Adjustable Dumbbell FAQs
Are adjustable dumbbells safe to use?
When used properly, adjustable dumbbells are as safe as regular dumbbells. When you move weight, there’s always a measure of risk, so it’s always a good idea to have a spotter available.
Are adjustable dumbbells worth it?
Adjustable dumbbells are a great addition to a home gym. They save an enormous amount of space, are cheaper than a full set of dumbbells, and they make switching weights much faster.
How do adjustable dumbbells work?
Adjustable dumbbells are single sets of dumbbells that can change weight. Most of them are basically handles with sets of plates attached. To adjust the weight, you generally have to twist a dial to select your weight, and then pick up the dumbbells, leaving the extra weight in the rack. For instance, if an adjustable dumbbell’s max weight is 50 pounds, that’s what it’ll have on the handle to start. If you want it to weigh 35 pounds, select that weight. When you pick it up, it’ll leave 15 pounds of plates on the rack, so that the dumbbell only weighs 35 pounds.
Can you drop adjustable dumbbells?
A couple of adjustable dumbbells are available with a warranty that covers drops, but generally speaking, you shouldn’t drop dumbbells — especially adjustable dumbbells. With many internal mechanisms at work, adjustable dumbbells can suffer severe damage on a drop, making weight changes difficult or even impossible to do with broken machinery. To get the most out of your adjustable dumbbells, try your best not to drop them.
Which adjustable dumbbells feel like traditional dumbbells?
Adjustable dumbbells come in many shapes and sizes, with some available in a caged form to add to the dumbbell’s durability and construction. However, these won’t have the feel of traditional dumbbells because of the cage getting in the way for dumbbell exercises.
For a more traditional feel, go for a pair of dumbbells like the NÜOBELL Adjustable Dumbbells or the Snode 80lb Drop-Proof Dumbbells. Aside from being a bit longer at heavier weights, both of these adjustable dumbbells have round plates with a flat head, making for a feel very comparable to a fixed dumbbell, especially with knurled handles.
