Notice from the HGR Team:
Adjustable Kettlebells do cost more than standard ones, but they are also Multiple Kettlebells enclosed into one. In addition to saving you much needed space, they often work out to be a very similar price.

Let’s take a look at the Best Adjustable Kettlebells available in 2021.

Grabbing a pair of adjustbale kettlebells can be one of the best things that you can do, providing you work out in your home gym. If you have a gym membership, you’re better off just using their equipment as it’s what you pay for! Kettlebells aren’t that expensive, but you will need a full set of them to maximise your workout effectiveness. For this reason, we’ve found some great adjustable kettlebells which offer many benefits. Let’s get into this. As always, we will show you the items, then provide the full guide below.


ISOGYM Adjustable Kettlebell

Our Favourite Adjustable Kettlebell
ISOGYM are on the rise, building their name for Adjustable gym gear. They’ve made a solid kettlebell here, with a very attractive price. It’s the best value adjustable kettlebell, in my opinion.

ISOGYM Adjustable kettlebell Review

ISOGYM have developed an adjustable dumbbell which resembles a traditional dumbbell. If you take another glance at the Bowflex one above, this looks completely different. It’s great to see that ISOGYM are paying homage to the equipment that it’s expanded upon.

You could argue that this kettlebell should be the #1 option & I’ll admit that this was very close. This kettlebell is much better priced, offers an extra weight option (with the same maximum 18kg weight) and it also offers safety functions for locking the weights.

I’ve made my mind up, it’s joint first. This Isogym one is now going to be the Best Value Kettlebell.

I couldn’t ignore the fact that this was over £50 cheaper, made of durable cast iron & powder coated to ensure that you will be able to hold it with comfort. Even if you’ve got a larger hand, you shouldn’t have any trouble with the 5.25cm handle diameter.

I also did an in-depth review on this one, which you can read here.

Bowflex 840 Selecttech review

If you’re looking for an adjustable kettlebell, you can’t go far wrong with Bowflex. They’re reknown for their gym equipment, specialising in their Adjustable weight technology. They make some dumbbells, which are the best in their field, too.

It seems that they’ve followed suit with kettlebells, offering the general public a chance to save space when kitting out their home gym. I really like their gear. Not only does this kettlebell look good, but it’s also a really effective solution.

The weights sit inside the casing itself & can be adjusted using the dial on the top of the kettlebell. This then automatically adjusts, selecting the desired weight that you requested. The time that this saves is incredible, as there’s no messing around with adding and removing weights manually. The handle is pretty comfortable, with a rubber finish to ensure that even in the coldest of gyms, you can still workout without your fingers going numb.

If you consider the build quality, practicality & comfortability of the Bowflex 840, then it quite simply is the best in its class. On the surface, £200 for a kettlebell does seem quite expensive. However, you’re actually getting every single kettlebell within the 3.5kg to 18kg range which offers a good weight for any workout. If you price up the costs of individual kettlebells, you might end up shocked that these adjustable kettlebells work out just as cheap. (Remember; you only have to store one set of kettlebells with these, too!).

Bowflex have made top quality products, for years. I’m a huge fan of this & it’s the deserved winner of the Best Adjustable Kettlebell for 2020. If you’re shopping with a lower budget in mind, there’s some other great options below which we’ve hand-picked for you.

Klar Fit Adjustable Kettlebell Review

Klar Fit have produced a great looking kettlebell, which has been recommended by many for it’s fantastic build quality. It looks very similar to the RepFitness Adjustable Kettlebell, which prides itself on looking like a traditional kettlebell but with the added technology of being adjustable.

It replaces 5 kettlebells, between the weight bracked of 8kg to 16kg, so it’s not quite as extensive as the choice between the above ones we reviewed. However, you might have no requirements for anything below 8kg, which means this could be your best option.

The handle of this kettlebell is on the larger side, but that’s not a problem, as it means you’ll be able to get a good grip and retain full control of motion. The locking mechanism features at the top of thew kettlebell, which will physically lock the weight inside, offering maximum safety for a secure workout.

It’s a great option, and rightly deserves it’s place on this list. However, there are some concerns which means that it’s not the outright best option. The price is very similar to the above ISOGYM kettlebell, yet there’s no 18kg option.

I think at this price point, I’d definitely choose the Isogym alternative.

How do they work?

Using an Adjustable Kettlebell

Your adjustable kettlebell will work in a very similar way to your standard ones. Some brands may look a little bit different, accomodating a longer bar (due to the weight being adjustable). An Adjustable kettlebell will be able to adapt for various weights, offering you the perfect workout companion.

There is a dial, usually found on the top of the kettlebell, which allows you to set the desired weight. Once set, the kettlebell will lock, to ensure your safety when swinging it. You’ll need to stop for a few seconds to change the weight, unlocking the clasp before starting your next set.

Although this will take a bit of time, once you master it, it’s faster than swapping your pair of kettlebells for another pair that’s waiting on a weight rack.

Benefits of Adjustable Kettlebells

Why you need them

Any adjustable equipment will carry the same benefits, being that the amount of space that you save is astronomical. For you to get kettlebells that weigh between 3-18kg, you’ll need to dedicate a weight rack which is around 5 foot wide. That’s quite a bit of space, if you’ve got a compact gym. An adjustable kettlbell will take up 1 foot. That’s quite a difference.

I’ve set a warning up at the top of the page, regarding the price of kettlebells. It’s to warn potential buyers that although they look expensive on the surface, they’re actually much more cost efficient than buying individuals. Look at the below example, using the Isogym adjustable as an example.

Type of Kettlebell3kg Weight5kg Weight8kg Weight10kg Weight12kg Weight15kg weight18kg weightTotal Cost
Traditional Kettlebells£12.99£18.99£26.99£38.99£54.99£62.99£69.99£285.93
Adjustable Kettlebells are clearly cheaper than purchasing individually.

It’s surprising to see that adjustables are cheaper than individual ones, I didn’t expect there to be that much difference in price. I researched the above intensely, finding the best priced ones on Amazon.

Should I swap Dumbbells for Kettlebells?

Quite simply, no! If you really need some kettlebells to perform some kettlebell swings, or you want them for another workout… there’s another product which is going to be perfect for your requirements. Instead of spending all of your budget on some weights, take a look at the below.

I like innovating, especially when it saves money! The above is a cheap way of converting your dumbbell to a kettlebell! It’s just a grip, or ‘Gryp’ as it’s known as. This will physically attach to your dumbbell handle and in 3 seconds, you’ve got the kettlebell that you wanted.

Are Adjustable Kettlebells any good?

Are they worth it?

You will need a wide range of weights regardless of your workout plan. You should be following a full body workout, which will require different weights for your muscle groups. For example, you should be able to chest press much heavier weight than you can bicep curl. Even if you’re focusing on cardio, a weight training session is perfect to mix things up.

You may be considering purchasing a range of different weights, but you’ll notice that the price of these soon adds up. If you’re focusing on lower weights, between 1-5kg, you may be better off with traditional kettlebells.

However, it’s important to also plan for future progression. Those weights may be heavy now, but going forward they’re going to get lighter as you get stronger. If you’ve got the spare budget, it’s worth getting heavier equipment that you can work up to. A little bit like buying a jumper that you can grow into, rather than replacing it after 6 months!

One of the biggest issues with speccing equipment for a home gym is the limited space. Most people will be working with a very limited space, we’ve even had some people that store their equipment underneath their dining table.

How to Choose the Best Adjustable kettlebell for your needs

Choosing a Kettlebell

I’ve provided a thorough review of all above kettlebells. I don’t just add a product for any reason, it needs to be worthy of a HGR mention! (That’s Home Gym Review).

Brands like Bowflex & ISOGYM specialise in Adjustable Home Gym Equipment & they offer great options for you. I’ve also added a cheaper alternative… plus an item that’s not a kettlebell at all….

Choosing the best kettlebell for your needs comes down to the following:

  • Price
  • Value for money
  • Durability: We don’t want it falling apart after 3 weeks of moderate use.
  • Design
  • Weight Options: The more weight options, the better!
  • Ease of Use: It needs to be easy enough to use. The less hassle, the better.
  • Safety: As these have specific locking mechanisms, safety is paramount.
