What we look for when reviewing adjustable dumbbells

The main 6 things we look at when it comes to adjustable free weights:

Best Adjustable Dumbbells

  1. Ease of use – The common size for gym mirrors is 3,4,5 and 6mm thickness. While there’s no hard and fast rules, we weight up the thickness of each gym mirror and always look at this spec.
  2. How fast they are to change – Not the most exciting thing but if a mirror has razor sharp edges we’ll look into that.
  3. Is the mechanism robust? – Less of an issue with glass mirrors, more a problem if you’re getting an acrylic mirror. Nobody wants a fun house effect on their fitness studio mirrors!
  4. How much weight do you get? – An obvious thing to check out is how much weight you’re getting for your money. This varies wildly from one set to the next and will of course be different requirement for each sex, age etc.
  5. Number of steps – The whole point of an adjustable weight is so that you have a lot of different possible ‘dumbbells’ with one set. More is always better so that’s one major thing we look at when reviewing adjustable free weights.
  6. Getting to grips with it – As with regular dumbbells, the size, shape, quality and general ‘grippiness’ of the handle of selectorised and spin-lock free weights is critical. Unless you’ve got chalk at home (no, neither have we) your hands can and will get sweaty! And it’s essential that your weight won’t slip and do damage to you or, worse still, your poor phone.

Hardcastle 30Kg Adjustable Dumbbell Barbell

This adjustable set comes with a barbell, meaning you can do more exercises with one set

A set of dumbbells with an innovative central connector, this set by Hardcastle is a great piece of gear if you’re looking for something to get you started working out, and you have to exercise wholly inside your home.

That’s because, for one, it can be used as dumbbells and a barbell, saving you massive amounts of space and cash on expensive and space stealing kit. It does this by using a connector to link both dumbbells together, forming them into a single longer bar.

Second, the weights are covered by a solid vinyl coating, that massively reduces the impact and helps to prevent dents in your floor.

Lastly, it’s surprisingly budget friendly, especially considering what you’re getting. The only issue is the total included weight is quite low. 30kg, 15kg per dumbbell, so if you need something a little more intensive, we recommend something else on our list.

Pros
  • Functions as a set of dumbbells and a barbell
  • Vinyl coated weights are floor friendly
  • Incredibly easy to use
Cons
  • Only 30kg total weight

How easy: Quick and easy
Power Block Adjustable Dumbbell

CAPTION

Looking completely different to everything else on the list, the Power Block is a smartly designed and easy to use piece of kit that’s utterly unique. The design is patented, so you’re not going to find anything else like these.

Each dumbbell can be adjusted from 2 to 22kg (5 to 50lbs) in 2.5lb increments, giving you a massive 20 weight range to work with. It’s also incredibly simple to adjust, using a pin system similar to what you’d find on most gym machines, and the weight just lifts off from the base, making it incredibly simple to change and use.

The plates are plastic coated, so they move smoothly across each other, and they’re less likely to damage anything if dropped, and the each weight takes up just over a half a square foot of floor space. They’re ridiculously small!

Overall, these are a fantastic pair of dumbbells that are simple to use, with a lot to offer, but you do pay a premium for it.

The upper weight of 22kg should keep most home gym’ers very happy and the overall build quality is excellent. Not cheap, but a good set of adjustables here.


Adjustable dumbbell buyer’s guide

Buying adjustable dumbbells is slightly more tricky than your regular variety free weights. But  fear not! Have a quick butchers of our guide to everything you nee to know about picking the perfect set of dumbbells with changeable weights!

How do adjustable weights work?

There’s two kinds of adjustable dumbbells, and we’ll cover each one in more depth.

Adjustable weights all differ slightly in their mechanism, but the principle is the same from one free weight to the next. You get a hand grip, and a base unit which contains a variety of weights. You insert the grip into this ‘stack’ of weights, select the weight you want and then lift up the barbell.

Do you need to buy a pair?

Spin lock style weights will generally come with two bars and a selection of weights. The more sophisticated selectorised weights, however, almost always come separately.

With these weights, if you’re looking for a pair, yes – you’ll have to effectively buy two of the same item. Having said that, there’s a WORLD of exercise you can do with one dumbbell.

Why are adjustable weights so expensive

There’s no getting around the fact that selectorised adjustable weights aren’t cheap. They’re far more expensive (often more than twice to three times as much as the tried and tested spinning lock weights). So why is this? The main reason is that they employ a far more elaborate mechanism, requiring a highly specialized tooling setup, costing a lot more money to make.

But look on the bright side. They might make a dint in your wallet but they’ll pay dividends in all the time they save.

Are selectorised weights safe?

Selectorised weights have a ‘fool proof’ locking mechanism that involved turning to lock the plates into position. It doesn’t matter how hard you try, there’s no way to remove those plates unless you return the weight to it’s dock. These weights are safe as dumbbells.

Having said all that – you do of course have to take precautions lifting any weights.

Why use adjustable dumbbells

The mundane dumbbell is one of the most flexible and efficient pieces of exercise equipment you can own.

Whether you’re using them for joint isolation exercises like curls (so many curls,) raises and flies, or you’re performing full body lifts or squats, a good set of dumbbells can carry an entire workout.

But most people don’t have the space for a full set of dumbbells of various different weights inside their house. Which leads us to an adjustable set.

Adjustable dumbbells all share one thing in common, a set of weight plates that can be changed, to give you various different weights to workout with.

The types of adjustable dumbbell

There are two types of adjustable dumbbell:

  1. Traditional adjustable weights
  2. Selectorised free weights

Traditional dumbbells

A set of traditional dumbbells are probably what most people think of when they hear the name.

Dumbbells like these have been around forever, and run the entire gauntlet when it comes to prices, features, weight ranges, and more.

Standard dumbbells like these normally come with a set of two bars, weight plates in various sizes, and spin-locks to hold the weights in place.

Simple and effective, but it can be a pain to keep changing weights. If you’re going to be changing weights often, you’re going to be doing a LOT of twisting on and off of those weights. While they’re cheaper, these weights are best used for when you’re not going to be swapping the kg around too often.

Selectorised dumbbells

Designed to make the process of changing weights much faster, so you can shift through sets and different exercises in seconds, selectorised dumbbells are getting much more popular.

Rather than holding a set of plates on with screw fixings, most selectorised dumbbells have simpler drop-in weight systems that can be locked in one movement, so you can change the total weight incredibly quickly.

Space efficient and much nicer to use, selectorised dumbbells are the better product, but you have to be careful, as they’re more vulnerable to damage if dropped, and might take a little while to get used to.
