What is an Adjustable Kettlebell?

Kettlebells are simply weights that resemble the old-fashioned hob kettle, excluding the spout. You can lift them, just like dumbbells and barbells. However, in contrast to dumbbells and barbells, you can manipulate them in some other ways. Most importantly, you can throw, swing, or carry them.

Adjustable kettlebells are similar to standard kettlebells. The only difference is that they allow users to adjust the weight to suit their needs, either increase the weight or decrease it.

Why Use an Adjustable Kettlebell?

Whether you follow a regime for a full body, lower body, or upper body workout in the UK, you have to buy some weights when undergoing some resistance training.

Some people end up purchasing three or more different kettlebell weights. Though, when you purchase them individually, they could be cost-effective. However, when you begin purchasing three to five weights, the cost involved can soon accumulate. Asides from this, getting the required space to keep your kettlebells may be another problem.

Adjustable kettlebells handle both issues mentioned earlier. This is because it provides more than five different weight levels at a less high or equivalent price. Also, they will only occupy the space of one kettlebell.

You can use a kettlebell for most exercises you cannot use a dumbbell for. Also, with a kettlebell, there are many dynamic and explosive exercises you can do. This means that you have a wider range of exercises and training options to work with.

Features to Consider when Choosing the Best Adjustable Kettlebells in the UK

Upper and lower weights

Picking a weight for anyone could be difficult because everyone’s level could be different. Generally, a reliable adjustable kettlebell should begin at 3kg. However, it should have weights up to 20kg to cater to more experienced users.

Number of weights

There’s no need to choose a kettlebell with multi-weights if you only find a few weights in the package. The number of combinations available should be at least six or more. There should be small steps up as well in between the levels.

Design and Aesthetics

The looks of kettlebells don’t reveal whether it is good or not. However, this could appeal to some people. A kettlebells’ overall design varies for different products. Some are awkward and clunky beasts, while some manufacturers took time to do something great.


It is not a good feeling to practice using something when you know it has a ‘knack.’ The good adjustable kettlebells are painless, quick, and you can swap them easily between weights.


Before choosing an adjustable kettlebell, you must consider your budget. Though the more expensive it is, the more quality it is meant to have. However, this is not always the case. There are cheaper options that will serve you well too.

Comfort and Safety

Indeed, the original kettlebells are not the safest things. Some are waiting to clink your ankle. However, many others have great designs and have smooth edges, supportive and wide angles, and very secure weights.

Reputable Brand Name

It is advisable to choose from brands that have a reputable brand name. They have been there, and users have been able to test their products. However, we don’t mean that new companies cannot manufacture high-quality products. Consider the quality and your safety above anything.

Ease of Use

Generally, when using adjustable kettlebells, this means three things:

  1. The handle must be wide enough to enable you to get both hands on it easily.
  2. The kettlebells’ shape must be very similar to the regular type to ensure you get the same swing style.
  3. The mechanism used in weight changing must be easy to use.
