Adjustable dumbbells are some of the most versatile pieces of equipment you can add to your home gym. Not only are they a space-saving alternative to owning an entire dumbbell rack, but they’re also a more cost-efficient option than just a pair of the best dumbbells.
To find the best adjustable dumbbells, our team of certified personal trainers, Olympic weightlifters, and fitness enthusiasts has personally used more than 30 sets of adjustable dumbbells and researched dozens more. Using our in-depth fitness equipment testing methodology, we rate dumbbells on a scale of 1 to 5 in categories that include:
- Durability: Scores of 4 out of 5 or higher favor dumbbells that use minimal plastic parts and profiles that can endure repeated use.
- Weight options: Looking at max weights and increments, we give a 3-out-of-5 score to dumbbells that top out at 60 pounds, making 10-pound jumps at most.
- Handle: A 3 out of 5 means the handle is fairly comfortable, although materials used may make for a lackluster grip.
- Value: Based on the market, we assess if the product is priced fairly for what it offers, giving top scores to competitively-priced, high-quality dumbbells.

Best Adjustable Dumbbells Overall: Snode AD80 Adjustable Dumbbells
The Snode AD80 Adjustable Dumbbells are a durable pair of adjustable dumbbells that cover a broad range of dumbbell weights. If only having 10-pound increments is alright with you, these are a solid choice of dumbbell, strong enough to withstand drops from up to 32 inches.
What our tester says:
“I’m more impressed with these dumbbells than I thought I’d be. They handle drops well and are built solid.”
Most Durable Adjustable Dumbbells: REP QuickDraw Adjustable Dumbbell
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
The REP Fitness QuickDraw Adjustable Dumbbell is the latest piece of innovative equipment for the company, with patented Lock-N-Load switches for quick weight changes. The dumbbells can go up to a maximum weight of 60 pounds, although they can be purchased at lighter weights and expanded from there. These dumbbells are extremely durable as well, tested for drops at various heights and angles; plus, they’re backed by a lifetime warranty.
What our tester says:
“My only callout is that the knurling on the QuickDraws are more passive than other dumbbells and barbells I’ve used. Otherwise, this is a solid piece of equipment.”
Best User-Friendly Adjustable Dumbbells: NÜOBELL Adjustable Dumbbells
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
The NÜOBELL Adjustable Dumbbells are great for people who want an easily adjustable dumbbell pair that feels more like a traditional fixed dumbbell.
What our tester says:
“After using these dumbbells for a while myself, I can say they are well-built and aesthetically pleasing.”
Best Adjustable Dumbbells for Beginners: Bowflex Results Series 552 SelectTech
Updated by: Amanda Capritto, CPT, CES, CF-L1, CNC, CSNC
The Bowflex Results Series 552 SelectTech adjustable dumbbells are the latest iteration of this popular home gym silhouette. Capable of reaching weights up to 52.5 pounds and featuring a quick dial adjustment system, they can be excellent for beginners and seasoned athletes alike.
What our tester says:
It’s a very fast adjustment; all you have to do is turn a knob on each side and make sure the numbers match.
Most Ergonomic Adjustable Dumbbells: REP x PÉPIN Fast Series Adjustable Dumbbell
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
The REP x PÉPIN Fast Series Adjustable Dumbbell are a new and improved version of the original Pepin Fast Series dumbbells, which are durable and innovative. At this price point, these will be some of the most popular adjustable dumbbells on the market.
What our tester says:
“The durability and construction on these dumbbells blows just about every other company out of the water.”
Best Adjustable Dumbbells for Versatility: Rogue Loadable Dumbbells
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
If you’re a fan of American-made Rogue products, these handles are a great, albeit pricey option for people who have change plates already.
What our tester says:
“There’s a good amount of loadable space on these dumbbells, but remember that you’ll also have to leave some space for the barbell collars so the weights are secured.”
Best Adjustable Dumbbell Set: PowerBlock Pro 100 EXP Dumbbells
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
The Pro 100 EXP Dumbbells are the latest set of adjustable dumbbells from Powerblock, ranging from 5 pounds to 100 pounds with 2.5- or 5-pound increment adjustments. The dumbbells begin at their first stage of up to 40 pounds, with three expansion kits that can move the maximum weight up to 60, 80, or 100 pounds. The dumbbells have the option to have a metal knurling as well.
What our tester says:
“These adjustable dumbbells are pretty balanced, especially at heavier weights. When you’re using a lighter weight, the balance of PowerBlocks is weighted down toward the cylinders in the dumbbell handle.”
Best Heavy Weight Adjustable Dumbbells: Ironmaster Quick-Lock Adjustable Dumbbells
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
The Ironmaster Quick-Lock Adjustable Dumbbells are some of the best adjustable dumbbells available. They’re the most similar adjustable dumbbell to traditional fixed dumbbells, they have a wide weight increment range, and they’re priced very affordably. If you own a home gym and want a set of dumbbells that doesn’t take up a ton of space, Ironmasters are a great option.
What our tester says:
“They look great, feel great, and can be relied on for years of use thanks to their quality construction materials.”
Best Loadable Dumbbells: Titan Loadable Olympic Dumbbell Handles
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
The Titan Loadable Olympic Dumbbell Handles are a great addition to any at home gym as a universal tool to target many muscle groups. They are built to last, and their added knurled grip is great for pushing through the end of a workout preventing any slipping. Would not recommend it for a beginner. These dumbbells are built for compound weight and are best for someone with more experience in strength training that may already have Olympic-style weights on hand.
What our tester says:
“After a few years, there is some slight corrosion on these. I keep them in my garage gym, which is not climate-controlled, and which is in the very hot South. They’ve lasted so long and are still in great shape.”
Best Budget Adjustable Dumbbells: NordicTrack 55-Pound Select-A-Weight Dumbbell Set
Updated by: Caine Wilkes, OLY, CNC, USAW-L1
NordicTrack’s 55-pound Select-a-Weight adjustable dumbbells are versatile and space-saving, offering users 15 different weight options in one.
Other Adjustable Dumbbells We Researched and Tested
We’ve seen some of the best adjustable dumbbells on the market in our testing—even making our own DIY concrete dumbbells—but not every set makes our top list. Here are some honorable mentions:
- Trulap 8592 Adjustable Dumbbells: These dumbbells have the greatest number of weight increments of any adjustable dumbbell we’ve ever used, but we left them off the list due to their high price and the fact they’re not as durable as some of our other top picks. You can learn more in our full Trulap Adjustable Dumbbells review.
- Pepin PRO Series Adjustable Dumbbells: These are great, but can’t be dropped and take a long time to change in comparison to Ironmasters. They also appear to be out of stock often.
- HAVAK Adjustable Triad: These are somewhat underground adjustable dumbbells featuring three different handles at different diameters to help increase grip strength. I’m a big fan of these, but they’re a very different weight option from what else is out there and are (honestly) in a somewhat separate category.
- Eisenlink Adjustable Dumbbells: As I explain in my Eisenlink Adjustable dumbbell video review, these appear to be a more budget-friendly version of the Ironmaster dumbbells. Read more in our Eisenlink Adjustable Dumbbell review.
- MX55 Rapid Change Dumbbell System: These are great and compact. However, they don’t have add-on extension kits available. We do like how quickly they change and how balanced they are, though. Read our full MX Select Adjustable Dumbbells review for more information.
How We Tested and Picked the Best Adjustable Dumbbells
Before testing adjustable dumbbells, we researched countless products from Amazon and popular brands. After narrowing our search, we tested each chosen model, rating them on how well they performed during training.
This means that, among many other movements, we performed lunges, alternating curls, hammer curls, overhead triceps extensions, lateral raises, single-leg deadlifts, and even bench presses on a weight bench. To help you choose the best adjustable dumbbells for your home training needs, our testers spent time lifting each dumbbell.

Everyone trains differently and has different fitness levels, so it’s important to note how each dumbbell feels during each movement and how it differs from others, and what they’re trying to mimic: fixed dumbbells. Personally, when I was testing the equipment, I asked myself if the shape of the dumbbell limited range of motion, if they felt unbalanced or uncomfortable, or if we closed our eyes, would we know we were using a dumbbell substitute?

Our rating system assigns a score to each dumbbell on a scale of 1 to 5 in categories that include the following:
- Construction: Top scores go to steel construction with minimal plastic used.
- Durability: Even though you shouldn’t drop adjustable dumbbells, we wanted to make sure they’d hold up to a little bit of abuse. Scores of 4 or more mean that they’ll last with maybe some minor wear and tear over time.
- Adjustment Speed: We timed how long it took to adjust the weight on these adjustable dumbbells. A score above 3 out of 5 means that the dumbbells were adjusted usually in under a minute, with top scores taking just seconds.
- Weight Options: We factored in the weight range, as well as the weight increments, with top scores going to profiles with weight capacities of 80 pounds or more, as well as those having small increments (5 pounds or less) to that maximum weight.
- Aesthetics: This is fairly subjective, but it’s a score on both how the dumbbells look and feel while in use. Top scores go to dumbbells that feel identical to a traditional dumbbell.
- Handle: How does the grip feel? Top marks went to handles with knurling or texture to provide a secure but comfortable grip.
- Value: Is the product worth the cost? A 3 out of 5 means that the dumbbell is priced fairly for its quality, but higher scores go to dumbbells offering a ton of features, durability, or weight options while still being competitively priced.
- Warranty, Financing, Returns: We checked that each company had financing options, a decent return policy, and a substantial warranty. Lifetime warranties earned top scores here.
- Customer Service: How easy was it to work with customer service? We took a look at how easy it was to contact a representative, as well as their helpfulness, giving top marks to companies that are quick to respond and knowledgeable about their product.
Along with online customer reviews, we average out scores to determine our best-of list seen before you now.

How Do Adjustable Dumbbells Work?
Adjustable dumbbells allow you to select from multiple weights or weight ranges on a dumbbell, essentially replacing many sets of fixed dumbbells in one silhouette. Most adjustable dumbbells use an adjustment mechanism to add or subtract weight plates from the dumbbell handle.
RELATED: Best Kettlebells / Best Adjustable Kettlebells
The weight limits can vary depending on the design of the dumbbells; more budget-friendly designs max out at around 50 pounds, while heavier pairs can go up to 90 or 100 pounds, or even heavier. Loadable dumbbell handles, on the other hand, use Olympic weight plates or bumper plates to load possibly hundreds of pounds on each dumbbell.
The adjustment mechanism can vary from dumbbell to dumbbell, as well, but here are some of the more common mechanisms:
- Dial: One of the more common types of adjustment mechanisms is a dial, in which the user rotates a knob (or the dumbbell handle itself) to select the desired weight. The rotation shifts a bar forward or back, securing the desired weights for your selected total.
- Selector pins: Another common method of weight selection is through selector pins. How the pins operate can vary; some will have sliding pop-pins that can be pulled out and moved to the desired weights. Others, like PowerBlock dumbbells, allow the pin to be completely removed and inserted to a different setting.
- Lock switches: Switches like those on the REP QuickDraws can be flipped up or down, locking each weight plate into place along the dumbbell.
- Plate-loaded: Plate-loaded dumbbells are basically handles with a loadable sleeve, allowing you to use your own weight plates or, in some cases, specially-designed plates for the dumbbells. Weights are then secured with a collar or a spin-lock mechanism.

Benefits of Adjustable Dumbbells
Resistance training, in general, has tons of benefits in muscle growth, improved strength, and more. When I talked to Chris Mohr, Ph D., RD, about the benefits, he added, “Resistance training can even improve bone density by stimulating bone formation. When muscles pull against bones while lifting weights, it encourages bone cells to produce more bone tissue, which in time increases bone density and reduces your risk of osteoporosis.”
Dumbbells are great too, but the initial sticker price of adjustable dumbbells might shock you. That said, if you pick the right pair, you might discover that adjustable dumbbells are some of the most worthwhile workout equipment you can own.
Adjustable Dumbbell Training Benefits
Dumbbell training, in general, is extremely effective, whether you’re looking to build muscle mass, do a HIIT cardio workout or burn fat. “Dumbbells are a great choice for beginners, too, since they’re easy to handle and can be used for a variety of exercises that target different muscle groups,” adds Chris. “They also allow for natural, functional movement patterns and help improve coordination and balance by engaging stabilizing muscles.”
People use dumbbells for a number of reasons. Chris explains the major benefit, though: “Dumbbells help in building muscle and strength by providing resistance during exercises. Resistance challenges the muscles and forces them to adapt, leading to muscle growth and strength gains through a process called hypertrophy.”
Here’s some other benefits of dumbbell training:
- Unilateral work identifies and eliminates bilateral deficits and imbalances1
- Increased muscle stabilization
- Improved trunk strengthening2 with free weights and unilateral exercises
- Countless exercises for the upper body, lower body, and core muscle groups
- Greater range of movement and variability in the exercise

Unique Benefits to Adjustable Dumbbells
Here’s a few unique benefits that adjustable dumbbells can bring to the table.
- Space-savers: The most obvious plus to an adjustable dumbbell is that it saves an enormous amount of space. A traditional dumbbell set easily takes up a substantial amount of flooring or takes up an entire dumbbell rack. With adjustable dumbbells, you can get between six and 30 dumbbells in the footprint of just one pair.
- Cost-effective: Depending on which adjustable dumbbell set you pick, you can save a significant amount of money by essentially buying multiple pairs at once.
- Durability: Although it can’t be said for every adjustable dumbbell, quite a few adjustable dumbbells are built to withstand a lot of wear and tear. Quality ones use iron and steel to form a solid, nearly indestructible piece of equipment. While typical rubber hex dumbbells can be more durable, that’s becoming the case less often.
Traditional Dumbbells Vs Adjustable Dumbbells
Although adjustable dumbbells can save money and space, there are pros and cons to each type of dumbbell. Here’s a quick breakdown of the good and the bad for adjustable dumbbells vs fixed dumbbells.
Traditional Dumbbells
Anyone who has spent time in a commercial gym is probably familiar with traditional dumbbells. Also called fixed dumbbells, these dumbbells are simply two weighted ends, or “heads,” connected by a dumbbell handle. The heads on a traditional dumbbell are typically hex- or round-shaped, although there’s no real right or wrong design.
Because traditional dumbbells don’t have the internal workings of many adjustable dumbbells, they can be more durable—although I’d never recommend dropping your dumbbells, both for your floor and dumbbells’ sakes. Because they’re built at fixed weights, you’ll need some serious space in your garage gym to have multiple pairs of dumbbells.
Adjustable Dumbbells
Unlike traditional dumbbells, an adjustable dumbbell can incrementally adjust the weight in the pair of dumbbells. Instead of needing a full set of dumbbells, a single pair of adjustable dumbbells will replace multiple pairs of dumbbells. Since they replace several weights, adjustable dumbbells can save space in your home gym—plus they’re often the less expensive alternative, too, costing less than an entire set of fixed dumbbells at similar weights.

Adjustable Dumbbell Safety and Precautions
I love lifting heavy, but you still have to be safe about it. Here are some tips and precautions you can take during your adjustable dumbbell workout to minimize your risk of injury or damage to your home gym equipment.
- Have a proper warm-up: The best warm-up exercises help lower your chance of a pulled muscle or similar injury. Warming up properly also helps improve your performance3. “A simple 5- or 10-minute warm-up of light exercise followed by dynamic stretches works well for most people,” adds exercise physiologist Chris Mohr.
- Use correct technique: If your form is wrong, you might be increasing your chance of injury. Make sure to prioritize good and proper form to avoid unnecessary stress on the wrong muscles and joints. Also, keep your form in check when picking up your dumbbells for your next set; lift with the legs! “Beginners should avoid jerky movements and not hold their breath during dumbbell exercises,” suggests Chris.
- Find the right weight: Don’t start off by maxing out. Slowly add weight as you get more comfortable with the exercise you’re performing.
- Store your dumbbells: Don’t just leave your equipment lying around. Having a proper storage rack or shelving for your dumbbells can help avoid accidents, like a trip or fall.
- Don’t drop dumbbells: Even if you have durable dumbbells, avoid dropping them. Because dumbbells are oddly shaped, the weights can bounce just about anywhere, which can cause damage to you, the dumbbells, or your gym flooring.
What to Look for in Adjustable Dumbbells
Since 2014, GGR has researched, tested, and reviewed it all: weight benches, squat racks, all-in-one home gyms, and more. We’ve also tested nearly every adjustable dumbbell with some semblance of quality that’s available. This includes the most budget-friendly, low weight capacity, imported models all the way to stainless steel, made-in-the-USA dumbbells with a 175-pound weight capacity.
RELATED: Best Back Exercises
In addition to my own training and testing, I’ve leaned on the collective opinions of the most die-hard home gym equipment owners in the known universe, our Facebook Home Gym Community.
In all this lifting of metal and plastic, I’ve found the things that are important and those which are not. There are certain features marketed by companies to sell their products that, in all honesty, provide little (if any) benefit to the user. In all this testing, I’ve found the following criteria to be the most important to look for when buying dumbbells:
Weight
Fixed dumbbells range in weight from 2 pounds all the way to 300 pounds or more. Few trainees need above 100 pounds for dumbbell movements, and if they do use more, they’re often using them for only a couple of movements. For this reason, an adjustable dumbbell’s ability to get as close to 100 pounds without being grossly oversized is important.
Dumbbells that can have a higher amount of weight added are even better, although not useful for most. Our favorite adjustable dumbbells allow you to grow the size and weight of your dumbbell over time.

RELATED: Barbells vs Dumbbells
Material
More durable materials like metal and nylon are superior to cheap and thin plastics for the longevity and safety of the trainee. Although it’s usually not wise to drop dumbbells, if you do, you better hope it’s made with a lot of heavy-duty metal as opposed to plastic. Metal weight sets are more preferred for their greater durability.
Warranty
Gym equipment breaks. Barbells end up bending, bumper plates fold, kettlebell handles separate from the bell, and adjustable dumbbells can (and do) break. The longer the warranty period and the more generous the use cases of a warranty, the better.
However, a warranty is only as good as the company servicing it. If a company isn’t going to be around for long, then a lifetime warranty will do you no good, so we factor in the lifecycle of the company making the dumbbells.
RELATED: Kettlebells vs Dumbbells
Price
Home gym exercise equipment is not an income-producing asset like the equipment bought by a commercial gym. For this reason and others, the price and, more importantly, the value of the adjustable dumbbells are extremely important.
The holy grail for adjustable dumbbells lies in the $500 to $800 range for expandable adjustable dumbbells with a high weight capacity. Cheaper adjustable weight dumbbells will prove to be more likely to get damaged because they likely sacrifice the kind of materials used.
Weight Indicator Readout
Is it easy to tell what weight you’re using? Does it require you to do mental math that can slow down your workout? Check out the labeling on the product. Some dials are simply in “sizes” of 1 to 10, and you have to do the math to figure out how much is on the bell. Other weight changes are clearly marked with weight totals, making it much easier to know what you’re actually lifting.
Balance in Hand
Trainees who come from a commercial gym with access to a full fixed dumbbell setup often remark on how awkward certain dumbbells that adjust can feel. This is true, but only for certain dumbbells, and this often goes away after a few workouts. Balance in the hand is important, so the user can focus on the lift rather than maintaining control of the weight.
Unit Size
Typically, the more compact a dumbbell is, the more it costs. Take Watson Dumbbells, for instance—the gold standard in the fixed dumbbell world. They’re as compact as humanly possible while relying on stainless steel instead of cast iron. The reason this is so nice is that it prevents the dumbbell from interfering with the movements.
Also, when it comes to home fitness, minimizing the space your equipment uses is often a priority. You can still find adjustable dumbbells with a maximum weight capacity that save you space because they literally put multiple pairs of weights into just one set.
RELATED: Best Compact Exercise Equipment

Durability
By and large, adjustable dumbbells shouldn’t be dropped. However, when hitting the end of your rep range or maxing out, it might be hard to set your dumbbell down carefully. The ability to be dropped without breaking is something we consider when testing, and something you should be aware of before purchasing.
Adjustment Speed
If you plan on doing any sort of isolation or bodybuilding movements that involve supersets, being able to change the dumbbell weights quickly is an important feature. If quick changing is a priority, you may want an adjustable dumbbell that uses a dial or quick switch mechanism. Otherwise, plate-loaded dumbbell handles might be fine for you.
Single Adjustable Dumbbells vs. Pairs
Beware, some adjustable dumbbells are sold as individual dumbbells rather than a paired set. Some manufacturers hide this fact in fine print, while others make it well known. Some people may like just having one adjustable dumbbell because it works for their training purposes, but most people should look for an adjustable dumbbell set with the traditional pair of free weights.
FAQs About the Best Adjustable Dumbbells
What are the best adjustable dumbbells on the market?
The ideal set of adjustable dumbbells for you will depend on a few factors, including your strength levels, your mode of training, and your budget. That said, our favorites for most people are the Snode AD80 Adjustable Dumbbells, which reach a solid 80 pounds. They also use a quick-changing dial for easy weight changes, and have a two-year warranty that covers drops from 32 inches.
Are adjustable dumbbells any good?
There are some downsides with adjustable dumbbells; the most common problem is that most lack the durability of fixed dumbbells. However, for 99% of trainees working out at home, adjustable dumbbells are vastly superior to fixed dumbbells thanks to their savings on space and cost.
Are 20-pound dumbbells enough to build muscle?
Yes, 20 pounds of dumbbells—or any sort of light resistance training—can be enough to help build muscle, especially for someone new to lifting. However, as you train over time, you’ll probably need to increase the load and resistance to continue building muscle and seeing strength gains.
RELATED: How To Build Muscle
What are the common problems with adjustable dumbbells?
While adjustable dumbbells can save space and cost in your home gym, they do have some issues to call out. The most common one is that many adjustable dumbbells aren’t as durable as fixed dumbbells. Due to the many moving parts and the use of plastic (in some designs), adjustable dumbbells are more likely to break or rattle if they’re accidentally dropped.
Along with this, adjustable dumbbells usually don’t reach the weights that traditional dumbbells can, and some designs are oddly shaped, leaving certain dumbbell exercises feeling awkward with a compromised sense of balance or range of motion.
