If you’re looking for the best adjustable dumbbells, you’ve come to the right place.
Dumbbells are an integral part of every commercial and home gym. They are versatile, can be used for various exercises, have a simple design, and last a long time. That said, purchasing multiple sets of dumbbells can cost you a lot, and they’d need a designated space and rack – an added cost.
On the other hand, adjustable dumbbells clear out this clutter, as a single pair can replace up to 10, 15, or even 16 sets of dumbbells. Now, this doesn’t mean that selecting a pair is easy. Multiple options are available on the market, and picking one can be tedious.
To that end, we’ve put together this buying guide that will list different options, with their details and pros and cons, to help you make an informed decision.

Best adjustable dumbbells overall: Bowflex SelectTech 552
No products found.
| Pros | Cons |
| Comes with storage trays | Relatively expensive |
| Goes from 5 lbs to 52.5 lbs per dumbbell | The length of the bar remains the same even if you’re not using all the weights |
| Eliminates the clutter of having multiple dumbbells |
The top spot on our list of best adjustable dumbbells overall goes to Bowflex SelectTech 552, and for good reason.
First off, each dumbbell can go up to 52.5 pounds with an increment of 2.5 pounds. This means that combined, these dumbbells weigh up to 105 pounds or 47 kg. Generally, working out with such heavy weights isn’t recommended for beginners as the focus should be on proper form rather than moving heavy weights.
That said, the dumbbells can be lowered to a minimum of 5 pounds each so that novices can slowly build their strength without compromising on form.
A neat feature of these adjustable dumbbells is the dial, which allows you to change weights effortlessly. Simply turn the dial to the desired weight, pick it up, and start working toward that insane pump. This also saves time as traditional dumbbells have a fixed weight or need a change of plates to get the weight you want.
For example, you could be pressing a total of 80kg on the bench, but the next exercise is bicep curls. I don’t imagine many people can bicep curl 80kg, so they’d have to rack the current dumbbells and look for a lighter weight. With these dumbbells, this process is made easier as it’s every weight you need – right there.
On top of that, the manufacturer claims that this pair replaces 15 dumbbells. So, the Bowflex SelectTech 552 is not only low-profile but also avoids cluttering up your home gym. All in all, this is one of the best adjustable dumbbells available on the market, and the dial functionality should increase your efficiency.

| Pros | Cons |
| Safety lock | Expensive |
| Goes up to 80 pounds | |
| Steel-knurled non-slip handle | |
| Replaces 16 sets of dumbbells |
If you’re looking for the best heavy adjustable dumbbells, look no further than the FF Finer Form NUOBELL.
First, this pair’s total weight is around 166 pounds, with each dumbbell going up to 80 pounds or 36 kg. The minimum weight for each dumbbell is 5 pounds, which can be increased to the maximum limit in 5-pound increments.
What this means is that each dumbbell could be used independently with the max weight for exercises like goblet squats. On the other hand, you can combine them for a good strength training session, which includes rows, bench presses, and stiff-legged deadlifts.
To change the weight, simply twist the bar in the “+” or “-” direction, showing you the increased or decreased weight. After that, simply pick it up and give it your all. The handle is non-slip due to the knurled steel, which provides good grip and stability.
The safety lock feature of these adjustable dumbbells is a great addition as you have to select the weight properly, and only then will you be able to lift it. For example, if the number shown is mid-way, instead of a full 35 or 40, it’ll remain in the holder. This should prevent any unfortunate events, especially if you’re using heavy weight, so this, in our books, is a massive win.
Best budget adjustable dumbbells: Core Fitness Adjustable Dumbbells
No products found.
| Pros | Cons |
| Contoured and textured grip | 50 pounds might be less weight for some |
| Low price point | |
| Aluminum weight cradles |
If you’re looking for the best adjustable dumbbells on a budget, then the Core Fitness adjustable dumbbells might be your option.
For starters, each dumbbell ranges from 5 to 50 pounds, which can be adjusted in increments of 5 pounds. Some prefer more fine-tuning with dumbbells, such as 2.5-pound increments, but if your training consists of progressive overload, this should work fine with you.
The Twist Lock technology should enable you to switch weights by twisting the grip. This should lead to a more efficient workout session. However, you will need to put the dumbbells back in the cradle to adjust the weight.
Lastly, the textured and soft handle grip should allow a more natural and comfortable grip. The contoured grip should also provide stability even when your hands get sweaty. This adds a layer of safety by reducing the chances of the weight slipping.
Overall, the Core Fitness adjustable dumbbells make for good gym equipment. They offer a 10-piece set in a single dumbbell, meaning you won’t have to invest thousands in buying multiple dumbbells and their racks. So, if you’re looking to operate on a budget, this should be music to your ears.
How to choose the best adjustable dumbbells
Before investing in any gym equipment, including adjustable dumbbells, it’s important to consider some factors that will help you make an informed decision. We’ve listed some of those below.
Weight range
The first thing you need to consider is the weight range. Generally, going for heavier dumbbells isn’t recommended for beginners, but since the dumbbells are adjustable, going for a heavier set can “future-proof” your setup. When you get to the point where you need more weight, you can simply add more; that way, you can avoid purchasing another set of dumbbells.
Budget
Take into account the budget you have and filter your options depending on that. As with everything else, high-end, mid-range, and budget options are available for adjustable dumbbells. So, filter your options based on how much you can spend on them rather than going for the highest price tag.
Grip
The grip of the dumbbells is a vital factor to consider. This is because a very smooth or rough grip can result in the dumbbells slipping when your hands get sweaty or feel like you’re holding onto sandpaper – which is less than ideal. So, ensure the grip is non-slip, nicely textured, and even padded, as it’ll help you hold onto the weights better, even if you’re sweating.
Build quality
Dumbbells generally go through a lot of wear and tear and suffer multiple bumps. So, to ensure that they last a long time, check out their build quality, locking mechanism, frame, and other components. This should help you gauge whether they’ll be able to sustain rough usage or not.
How heavy should my adjustable dumbbells be?
Your dumbbells should be as heavy as you can easily handle them. Moving heavier weights by compromising your form is never recommended. That said, a maximum of 50 pounds per dumbbell should be a good starting point, or you can go for a heavier set for future use.
