Starting off with our overall pick for best adjustable dumbbell is the BRAINGAIN 9-in-1 32kg Adjustable Dumbbell which comes from a company that emerged during the pandemic, and impressively, they've already put forth a commendable product lineup.

This particular dumbbell set is a standout, offering weight adjustments from 2kg to 32kg in 9 convenient steps, essentially giving you 9 pairs of dumbbells in one sleek unit.

What's really neat is the twist handle adjustment, which results in flat dumbbell ends, ensuring comfort when resting on your legs pre-exercise.

The pricing is also competitive which is currently at around £350, making it a value-for-money option without sacrificing quality or customer service.

Although BRAINGAIN is quite new to the market, we have been impressed with their adjustable dumbbells which are functional, and fairly priced making them a good choice.


  • Wide weight range: Adjusts from 2kg to 32kg in 9 steps, effectively providing 9 pairs of dumbbells in one.
  • Quick weight change: The handle twist weight change is so far the fastest adjustable dumbbell we have found.
  • Comfortable: The flat ends of the dumbbells are comfortable to rest on your legs and they are compact.
  • Price: Competitively priced at about £350 at the time of writing this post.
  • Customer service: BrainGain have focused on the quality of their customer service to ensure customers are satisfied.


  • New Company: As a relatively new company, long-term durability and product reliability are not as established compared to older brands. But so far, they are holding up well.

Sold as a Pair? Yes


Next up, we have the PowerBlock Pro 100 EXP Adjustable Dumbbells, brought to us by a brand with a strong legacy, known for their adjustable dumbbells since 1991.

With their trademark block design, they offer a comfortable setup for exercises like chest press and shoulder press as you can rest the dumbbells on your legs without discomfort.

Among various options, the Pro 100 EXP starts with a base maximum weight of 18kg and can be upgraded to a maximum of 45kg.

A nice bonus is that when you are adjusting the weight, the dumbbells will be shorter when less weight is selected. This helps to avoid the dumbbells from feeling bulky when being used.

While not the cheapest on the market, they offer added value with a reassuring 5-year warranty.

The only minor downside is the two increment weights that need to be inserted into the handle to make the smaller weight adjustments. Although it's a quick process to add the weights, it's an extra step to consider.

Overall, these are durable and versatile dumbbells that offer comfort and a solid warranty, making them a worthy investment.


  • Well know brand: PowerBlock is a well-established brand known for quality since 1991.
  • Comfortable to use: The iconic block design is comfortable for various exercises.
  • Upgradeable: The base weight is 18kg but can be upgraded to a maximum of 45kg per dumbbell.
  • Dumbbell length varies: The length of the dumbbells shortens as less weight is selected, enhancing comfort.
  • Good Warranty: Comes with a reassuring 5-year warranty.


  • High cost: Not the most budget-friendly option in the market.

3. BrainGain 40kg Octagon Adjustable Dumbbells (Pair) - Best 40kg Adjustable Dumbbells


BrainGain 40kg octagon dumbbells

Adjustment Type
Handle Twist
Weight Range
2.5kg to 40kg
Weight Increments

2.5kg, 5kg, 7.5kg, 10kg, 12.5kg, 15kg, 17.5kg, 20kg, 22.5kg, 25kg, 27.5kg, 30kg, 32.5kg, 35kg, 37.5kg and 40kg

Sold as a Pair? Yes


If you are looking for a pair of slightly higher weight capacity adjustable dumbbells than the first pair we saw from BrainGain then their 40kg pair of Octagon dumbbells are worth considering.

They have an impressive weight range from 2.5kg to 40kg in 2.5kg weight increments which gives you 16 different weight dumbbells in one pair. So there are plenty of weight adjustments to choose from allowing you to easily find a weight that works for your strength.

BrainGain has gone with an octagon shape for this pair which prevents them from rolling away if you leave them sat on the floor, unlike the round version. But some people like it when they can roll the weights on the floor. However, they do have a round version that is 40kg as well, so you can choose which style you prefer.

They use the same twist handle design as their 32kg pair which makes it very quick and easy to change the weight.

Plus, thanks to this twist handle design, the ends of the dumbbells are flat making them comfortable to rest on your legs. But it also changes the length of the dumbbells depending on how much weight you have selected.

So if you only have 10kg of weight selected, the dumbbells are much shorter than when the full 40kg is selected.

Our final verdict, the BrainGain 40kg Octagon dumbbells are very comfortable to use and the compact nature of these dumbbells makes them easier to use. Combined with the higher weight capacity and great price at just under £500, there isn't much to not like.



  • UK-Based Brand: BrainGain are UK-based brand with great customer service.
  • High-Quality Construction: BrainGain has made a name for itself for high-quality dumbbells.
  • Wide Weight Range: Ranges from 2.5kg to 40kg, with increments of 2.5kg, offering flexibility in workouts.
  • Comfortable Grip: Ergonomic grip design adds to the comfort of use.
  • Value for Money: Priced at about £500 they are great value for money.
  • Variable Length: The variable dumbbell length keeps the dumbbells as compact as possible.


  • Dumbbells Don't Roll: This will depend on your personal preference but the octagon shape stops the dumbbells from rolling on the ground. 

4. NordicTrack 25kg Select-a-weight dumbbells

Sold as a Pair? Yes


Next up we have a 25kg set from NordicTrack who are well known for their cardio equipment but not so much for their strength. But as we would expect from NordicTrack their Select-a-weight set is good quality and caters to their target audience.

It offers 15 different weight increments from 5kg to 25kg using a select-a-weight mechanism. But NordicTrack has adjusted the mechanism so that the length of the weight varies depending on the amount of weight selected.

This helps to keep the dumbbells compact, unlike the models from BowFlex which are always the same length. An added bonus of their design is that the ends of the dumbbells are flat making them comfortable to rest on your legs while getting ready to do an exercise.

One feature we love on this set that we don’t often see at this price point is a knurled metal handle. Competitors often have a plastic/ rubber handle which isn’t as durable as this handle design.

While we would have liked to see the starting weight a little lighter. The NordicTrack dumbbells are of great quality and excellent value for money, especially in comparison to the BowFlex SelectTech 552.


  • Trusted Brand: NordicTrack have a reputation for good quality gym equipment.
  • Price: Competitively priced and provides good value for money, especially in comparison to BowFlex.
  • Weight Increments: With 15 different weights to choose from you can find a weight that's right for you.


  • Starting Weight: Would have liked to see a slightly lighter starting weight.

The Bowflex SelectTech 552 is possibly the most well known pair of dumbbells in this list and is one of the original turn dial systems.

There are only a few minor differences to the pair of BrainGain dumbbells we looked at they also provide a weight range from 2 to 24kg in 15 increments.

The sleek design is eye-catching, and the quick weight change mechanism makes it convenient for varied workouts.

However, there are some notable downsides. The price tag is on the higher side, particularly when compared to the model we looked at earlier. They also can't be upgraded to add more weight as you get stronger.

Additionally, the bulky 40cm length remains constant, regardless of whether 2kg or 24kg is selected. This can make them feel bulky when trying to perform certain exercises.

The Bowflex SelectTech 552 is a good quality product but may not be suitable for those seeking a higher weight range or a more compact design.


  • Well-Known Brand: One of the original turn dial dumbbells from a reputable name in the industry.
  • Versatile Weight Range: Combines 15 different weight dumbbells into one, ranging from 2 to 24kg.
  • Quick Weight Change: Allows for very quick adjustments between weights.
  • Aesthetic Appeal: Attractive design adds to the visual appeal.


  • Price: Relatively high cost, especially considering the maximum weight is 24kg.
  • Lack of Expandability: No option to expand beyond the maximum 24kg weight.
  • Bulky Design: Constant 40cm length can be cumbersome.

The IronMaster Quick-lock Adjustable Dumbbells are a powerhouse for dedicated weightlifters.

Offering an monstrous weight capacity of 74kg with add-on kits, it will test your limits.

Priced at approximately £700 for the 34kg base pair, they are an investment.

To max out, you need the 54.4kg and 74.8kg add-on kits, each costing around £400. So, the total is about £1500 and we would recommend the dumbbell stand to help you change the weights quicker.

The price might seem steep, but it's mirrored by the quality. These dumbbells are comfortable, resilient, and constructed to survive the toughest workouts.You can toss them about without fear of damage.

7. York Fitness Olympic Dumbbell Handles

If you are on a limited budget then the York Fitness Olympic Adjustable Dumbbells are a great choice if you already have a collection of Olympic weight plates at home.

These Olympic dumbbell handles may be a little cumbersome due to their size, and the spring collars may slow you down a tad, but their cost-effectiveness and versatility outweigh these minor hiccups.

The weight capacity of these dumbbells is considerable, we managed to load over 70kg on each handle, granted you need enough weight plates on hand.

However, keep in mind that loading them up with numerous 10kg plates can make them bulky.

All things considered, these dumbbells are a reliable, cost-effective solution for those seeking to build or enhance their home gym setup without breaking the bank.

Just ensure you're ready to deal with a bit of bulkiness and slower adjustments from time to time.

But here is a quick tip, to speed up the process of changing weights, consider investing in Olympic clamps. They usually slide on and off the handles more quickly than the standard spring clips.


  • Cost effective: If you already own Olympic weight plates, these handles will only set you back about £50.
  • High capacity: Assuming you have enough weight plates, you can load up these handles and get about 70kg weight per dumbbell.


  • Bulky: The fixed length of these dumbbells makes them feel a little bulky to use.

The dumbbell handles being compatible with standard 1-inch weight plates makes it straightforward to add more weights as your strength progresses.

These York Fitness dumbbells are an ideal choice for beginners or those who value cost-effectiveness over speed of weight changes.

As such, they serve as a solid entry point to get you on your weightlifting journey without emptying the bank account.


  • Budget Friendly: Currently costs about £70 and comes with the weights to get started.


  • Slower weight change time: Taking the weights on and off the bar can be quite slow.
