How to Find the Best Adjustable Dumbbells

When you’re wondering how to find the best adjustable dumbbells, a lot of considerations come into play. They’re all pretty pricy, but when does the extra cost stop being worth it? Does shape matter? Are some safer than others? Here, we’ll explore how to decide if a set of dumbbells is the right choice for you and take a look at some of the best on the market.


Why Are Adjustable Dumbbells a Good Option?

There are so many reasons why adjustable dumbbells might make the most sense for someone starting or adding to their home gym. They save space, grow with you, can be less expensive than individual sets of dumbbells, don’t require special storage, and more.

You Can Save Space

If your home gym area (whether it’s a room or a corner) doesn’t have a lot of extra room, choosing adjustable dumbbells makes perfect sense. Instead of buying a rack or lining your dumbbells up along a wall somewhere (or worse, stacking them up in a disorganized heap that’ll turn working out into a chore as you’re always hunting for the right ones), you can just get the one set of adjustable ones, set them in the corner, and use your leftover space for something else, whether that’s a new machine or just daily living.

You’ll Get the Weights You Need Now and Later

You’ll probably increase your strength faster than you think, which could end up being good news (you’re stronger!) and bad news (you’ll have to spend more money and find somewhere to store your new dumbbells) if you’re not using an adjustable set that allows you to increase weight as you progress.

There won’t be any issues if you’re feeling like you can lift more one day—no stalling until you can pick up a new set in a higher weight. Simply move the slider or turn the dial and you’re good! Obviously, you could still max out with an adjustable set, too, but that’ll take a while for the average user with decent set of weights.

You probably won’t find a new exercise move you want to do but can’t find the right weight for very often, either, whether that’s a high weight or a low one.

You Could Save Money

Unless you know for a fact that you’ll be maxing out on ten- or 15-pound weights (and maybe even then) with no desire to increase weight past that point, there’s a pretty good chance you’ll end up saving money and getting more for your money if you purchase the best adjustable dumbbells for your workouts.

Individual dumbbells are not cheap, and the higher in weight you go, the more they’ll cost. At some point, pretty early on, you’ll surpass the price of a pair of adjustable weights—even the really nice sets.

You Won’t Need Extra Storage

While you could get a stand for your adjustable dumbbells, it’s not completely necessary. With regular dumbbells, once you have a few sets, you’ll probably want to buy a rack to keep them organized and free up some floor space.

The racks aren’t exactly inexpensive, and wouldn’t you rather put that money toward something that improves your body instead? Factor that into the equation when you’re trying to find the best dumbbells for you.

How to Find the Best Adjustable Dumbbells for Your Needs

There are a ton of options on the market. They vary in price, shape, weight, and more. So how to find the best adjustable dumbbells to match your needs? 

Can You Add Weight to the Whole Set?

Some adjustable dumbbells let you ease into the commitment, at least a little. You can buy a set that goes up to a weight that will challenge you. Once you’ve maxed out there, you can buy more weight to add. Keep in mind, these expander sets can sometimes cost just as much as the original set.

What Are the Weight Increase Increments?

Also under the “adding weight” category, look at the increments you’ll be able to increase by. In some cases, the increments are small enough to be ideal for steady progression.

Progressing on upper body work may be easier with smaller increments. If the jumps in resistance are large (like five pounds vs. 2.5), you may have to complete more reps with the lower weight each session until you’re comfortable going up to the next available weight.

When you’re performing lower body exercises and holding the weights in your hands, the increase will be doubled. If you’re using two dumbbells, an increase of 2.5 pounds on each dumbbell is really five more pounds, but if your weights increase by five, you’re adding a whole 10 lbs at once to your squats or lunges, for example). Another option would be to increase the weight on one dumbbell and adjust your grip to perform the move with just one.

What’s Your Budget?

Piggybacking off of the last point, what’s your budget right now, and do you see yourself wanting to make a similarly priced addition to your adjustable dumbbell set in the near future? Will you need to add a line to your budget to make sure the money’s there around the time you’ve “outgrown” the first set of weights?

There’s also the possibility of getting a set with more weight right off the bat if your budget allows it.

Do You Need a Traditional Dumbbell Size?

The shape of adjustable dumbbells can sometimes be one of the trickiest things to deal with when you’re looking into buying a set. In some cases, the dumbbells may be especially long, making moves like bicep curls a challenge when you want to perform curls with both arms simultaneously.

In other cases, the weights may have a rectangular shape but shorter width, which could feel strange overall at first, as you figure out where to grip the weights for different exercises.

Ease of Use

Let’s be honest: if your adjustable dumbbells are a pain to use, it’s just one more mental hurdle to jump over when it’s time to work out and you don’t really want to go do it. (It happens to all of us!) One person’s “mildly annoying” is someone else’s “I won’t feel like using those, ever.”

Look at the designs you’re considering with a careful eye. Do you have to remove clamps or collars to add or remove plates? Turn a knob? Slide a piece of plastic out of one set of slots and into another (and how flimsy is the plastic—is the transition quick?).

Beyond just being potentially annoying, there are time concerns with adjustable weights. If you’re doing your own thing and have a large block of time dedicated to working out, even the clunkiest weight changes won’t ruin your workout.

If you’re following videos, though, or tend to only have a quick 30–45-minute chunk of time where every minute counts, you’ll want to be able to make those weight changes quickly and effectively.

Safety Concerns

Look for potential weak spots in the design of any adjustable dumbbell set you’re considering, then check reviews for comments about anything like plastic pieces or plates breaking. If either of those things happen while the weights are in use, you could be injured. That’s one thing regular dumbbells have over the adjustable styles—there’s less to break.

My Top Recommendations

There are plenty of adjustable dumbbell sets out there, with a range of features and price points, but here are my top picks, in case you’re looking for a starting point:

PowerBlock Elite

The basic PowerBlock Elite set will go from 5-50 lbs, adjustable in 2.5-lb increments, but there are two add-on kits you can purchase later (one to increase to 70, then one to take you to 90 lbs). PowerBlocks have a square shape that will take some getting used to, but they’re not clunky or uncomfortable to use. The grips are even padded.

Though the plastic slider that helps you select the weight can be annoying to insert at times because it doesn’t always seem to want to go correctly on the first try, it’s easy to know which weight you’re selecting at a glance because the set is color-coded.

PowerBlock Elite Dumbbells

Weight range of 5-50 lbs per hand. Change weights quickly and easily with the secure magnetic polypropylene pin.

Bowflex SelectTech 552

The Bowflex SelectTech 552s are a favorite because they’re the familiar dumbbell shape and have a comfortable grip, plus they’re easy to use, thanks to the dial design. If you’ll never need over 52.5 lbs, this is a great pick. Since you can’t add to them, this may not be the best choice for lifters who hope to lift very heavy.

You can get financing on these, which is nice. There’s also a 2-year warranty.

Best Overall
I Personally Prefer the 522s | Bowflex

I own both, but I use the 522s more. They are just more comfortable to use (better handle for the weight) and easy to store. They are also 50% less expensive. Worst case, start with the 522s and add the 1090s later when you need them.

NordicTrack Select-a-Weight

Here’s another great set from a trusted name in the fitness world. The NordicTrack Select-a-Weight dumbbells are expensive at $599.00, but there is 0% APR financing for 36 months through the NordicTrack website, so that takes some of the sting out of it.

There’s a 30-day return policy, so you won’t be stuck with them if you find they’re not for you.

You’ll get weights in 10 through 55 lbs, adjustable in 2.5-lb increments. It’s quick and easy to switch between weights and the shape is one of the best out there—similar to traditional dumbbells but with octagon-shaped plates that keep them from rolling.

You also get a year of the iFit app with your purchase, so you’ll have some trainer-led strength training programs to follow. If you have other equipment in your home, like a treadmill, bike, or rower, you’ll be able to use the app with that, too. If you’re not interested in iFit, I wouldn’t recommend these weights unless you can find them for much less (used, perhaps).

Other than that, my only concern with these is the amount of plastic on them. It’s not a dealbreaker, but there are other options out there that have more metal and don’t cost as much.

NordicTrack 55 lb Select-a-Weight Dumbbell Pair | Amazon

Experience a Full Body Workout: Enjoy total-body strength training in the comfort of your own home with the NordicTrack Select-a-Weight Dumbbells. With a max weight of 55-pounds each, these versatile dumbbells can replace 30 weights in one compact, easy-to-use set.

Flybird Adjustable Dumbbell

The Flybird adjustable dumbbell only has a 5-25-lb range, but it’s sold as a single dumbbell instead of a set. On a tight budget but have enough time to work both sides of your body separately?

Buy the one dumbbell for just over $100.00. Bigger budget but less time (or a need for more weight for lower-body moves)? Grab two for about $250.00. 

FLYBIRD Adjustable Dumbbell | Amazon

FLYBIRD adjustable dumbbell supports diverse strength training by changing different weights. Adjustment weights from 5lb to 25lb, even fitness beginners are very easy to use. It is a great choice for modify muscle lines and strong muscle fibers.

Ironmaster Quick-Lock Adjustable Dumbbell System

The Ironmaster adjustable weights are made to last and be extremely safe. There’s not much on them that could break, and they’re made up of iron and steel. They’re available in 5-45-lb and 5-to-75-lb sets, but can be expanded to 165 lbs.

These are exceptionally expensive for adjustable dumbbells, but between the amount of weight you can add, the lifetime warranty, and the durability, you’ll probably never need to buy another set. You may be passing them down to your kids and grandkids one day. If it’s in your budget, this is the set I would recommend above all others.

Ironmaster 75 lb Quick-Lock Adjustable Dumbbell System | Amazon

Quick-lock design adjusts from 5 to 75 pounds in 2 1/2 pound increments in just seconds.

Advantages of Adjustable Dumbbells

There are plenty of advantages to consider when you’re looking at how to find the best adjustable dumbbells. Not all sets will have all of the advantages, but there’s quite a bit of overlap. After that, it mostly comes down to personal preference.

  • They take up very little space compared to sets of traditional dumbbells, if you were to buy a set for each weight increment and try to store them.
  • There’s a good chance you’ll spend less on the adjustable set than you would on a variety of traditional dumbbells.
  • You can get an adjustable weight set that gives you room to challenge yourself while also allowing for smaller incremental increases.
  • When you buy a pair, there’s not a big jump from one weight to the next; when you’re buying traditional dumbbells, you may not be able to find the exact weight you need for your collection when you’re ready.
  • You don’t need (though you can purchase) a weight stand or rack. With traditional weights, you’ll eventually need a rack to help you stay organized.

Disadvantages of Adjustable Dumbbells

Though adjustable dumbbells make a wonderful option for most people who lift weights at home, they’re not perfect. Here are some disadvantages to take into consideration:

  • It takes more time to adjust the weight on a set of adjustable dumbbells than it does to set down one pair of weights and pick up another one, assuming the collection of weights is well-organized.
  • There are more moving pieces on a set of adjustable dumbbells than there are on a regular set of dumbbells, which means there’s more that could go wrong, like cracked or broken plates, piece to lose, plastic pieces that break, etc. Plus you have treat them with more care than you would a regular pair of dumbbells (always set them down gently).
  • Certain shapes or sizes won’t be as conducive to certain exercises as traditional dumbbells or even other types of adjustable dumbbells.
  • Weights can stick and take a few more seconds to change, and some designs (like the selector pin one of the PowerBlocks) may not always be quick to work with.

 Safety Tips for Using Adjustable Dumbbells

There are a few things to think about when you use adjustable dumbbells that you don’t really need to consider when you’re using traditional dumbbells.

  • Check for damage before each use. Adjustable dumbbells have moving parts, unlike conventional dumbbells, and that means there’s room for things to break.
  • Make sure everything is secure on the dumbbell before you start to lift. For example, the PowerBlock Elites have the option to insert or remove extra small weights in the handles and those need to be secured.
  • Be especially gentle with them—no dropping them or tossing them around. Again, they’re easier to break than other options.
  • Always, always read as many reviews as you can for any set to get a feel for what may commonly go wrong. Some sets are prone to breakage and may result in injury.

Top Q&A

You probably have a few questions rolling around in your mind about how to find the best adjustable dumbbells and whether they’re even the right choice for you. I’ll try to answer them here:

Question: Which adjustable dumbbells are the best?

Answer: It really depends on your needs. Some of the best are PowerBlock Elite, Bowflex SelectTech 552, NordicTrack Select-a-Weight, Flybird, and Ironmaster.

Question: Are adjustable dumbbells worth it?

Answer: If you have the space and budget for conventional dumbbells, maybe not. If you want the most you can get for your money and have limited space, then absolutely.

Question: Where can I find adjustable dumbbells?

Answer: Sporting goods stores (Dick’s Sporting Goods, Academy Sports, etc.), Amazon, even Walmart and Target carry some. You can also go to the brand’s website (for example, PowerBlock, Bowflex, Ironmaster, NordicTrack, etc.) in some cases and order directly from there.

Question: Are Bowflex adjustable dumbbells worth it?

Answer: Yes. The length can take some getting used to, but they will help you build strength and they’re comfortable to use. Some people prefer the shape of these over others, like PowerBlocks, because they’re similar to regular dumbbells.

Question: Why are adjustable dumbbells so expensive?

Answer: There are a couple of reasons adjustable dumbbells are such an investment. In reality, they’re not that expensive compared to conventional dumbbells; it’s just that you don’t get the option of buying the different weights over time. You’ll be buying at least the equivalent of several pairs of dumbbells at one time. A more complicated design is also involved with the adjustable dumbbells, so you’ll be paying for the time and skill that went into making them.

Question: Can dumbbells get you big?

Answer: With a diet that supports your goal, the right program, and enough of a weight range to continually challenge your muscles, yes. You may prefer to switch to a barbell or other gym equipment over time, but dumbbells can help you put on quite a bit of muscle.

Question: Are PowerBlock dumbbells worth it?

Answer: Yes. These are durable and a length that shouldn’t interfere with your ability to do most exercises. The shape may take some getting used to, but they’re easy to use and expandable.

Question: Where can I buy cheap adjustable dumbbells?

Answer: If there’s a secondhand store near you, try that. Even better if they specialize in fitness and sports equipment, like Play It Again Sports. Some sets are available at Walmart for around $50.00, and if you’re in a pinch but just want to get started with something, even if it’s not the largest range of weights, you may have some luck on Amazon.

Question: What size dumbbells should I buy?

Answer: That depends on how strong you are now, how much you hope to be able to lift later, and whether you’re interested in expanding the set you have at the time or would be fine with selling the old set to upgrade to a newer set with a higher weight range when the time comes.

If you have some dumbbells or other items that you can use in their place on hand, see how many reps you can do before you can’t do anymore. If you can do 15 with ease, you’ll need something heavier.

If hitting eight reps is a challenge, you’ll need something lighter. If you have the opportunity to try different weights in a gym or at a store, you should be able to get a good enough idea to determine the range you need for a few basic exercises.

Play around to get an idea of how much weight you need right now and how much you think you’ll need in the near future. Then you can decide which are the best adjustable dumbbells for you.

Conclusion: How to Find the Best Adjustable Dumbbells

So, how to find the best adjustable dumbbells?

Look at your current routine and goals.

Take an honest look at your current routine and your future goals. How much weight do you need right now and how much do you think you’ll need later? Can the set you’re looking at be expanded, or will you need to replace the whole set once you’ve gained strength?

Consider shape and size against your frame.

Is there one shape you prefer over others? One that’s better for your body type? For example, if you’re petite, you may find some moves with the Bowflex weights more uncomfortable to perform than they would be with, say, PowerBlocks. If you have large hands, PowerBlocks may not fit your frame well and you’ll do better with another option with a more traditional dumbbell design.

How will you pay?

What will your budget allow? Would 0% interest financing make you comfortable with a heavier pair or one with a design you prefer?

When do you need “the” set for you?

How soon do you need them and is your top choice available? Would you be okay with the “best adjustable dumbbells” right now, with the plan to sell those and upgrade when what you really want is available later?

Adjustable dumbbells with a decent amount of weight involved are an investment, so there’s a lot to think about and consider.
