Why choose an adjustable kettlebell instead of a set?

  • Save space
    One of the huge benefits of training with a kettlebell is it is so compact, you can take it almost anywhere. But as you progress in strength and skill, you will find yourself needing more and more sizes. The adjustable kettlebell can weigh 12, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 or 32 kilograms and can be easily adjusted to meet your needs.
  • Save money
    Buying all those bells would tally up to nearly $1,000. By buying an adjustable set you save yourself at least $700, not to mention the shipping savings.

Why not to choose an adjustable kettlebell?
Although this is a fantastic tool, it is not recommended for gym owners who are teaching classes, or those who require a fast transition of sizes, as changing the weight can take a minute or two.

Wish I had bought years ago!

Very pleased with Bells of steel, the customer service has been good, shipping rates are less then other places I checked, delivery was fast or on time. As for the Adjustable KB it is as advertised, I was sold on this product After watching several Mark Wildman videos on you tube, this one is exactly the same as the other brand he got but from a Canadian seller! I like that the handle seems slightly thicker then other competition kettlebells I have used. I love that it can do the 1kg increases through the 12-32kg range, with a proper Kb design. I plan on using 2.5lb standard plate to fill the 13 & 31kg gaps or if can find a true 1kg might buy. I got two so I can do double work and or have two different weights on the go for light / Heavy single kettlebell program structure. The Quality seems great out of the box, we will have to see how the threads hold up from sliding the plates on and off over time, I'm not one to drop, throw or juggle kettlebells it would be interesting to hear how this would hold up to that type of use. as for suggestions would like to see a1kg plate that fills the two gaps even if it was a extra charge, and an expantion plate option some thing in the 24-28kg range molded to fit in the top or bottom half so can build above 32kg with similar jumps.

The adjustable competition kettlebell rocks

I have been really pleased with this bit of kit. It needs about 5 or 10 minutes of work with an emery cloth to smooth the edges where the two halves meet but otherwise it is a thing of beauty. Changing weights takes less than a minute. I'll have no hesitation in getting another if I start doing double KB exercises. Ordering from Bells of Steal was a treat. Dead easy and the 'bell arrived almost a week earlier than expected. A true pleasure to deal with.

Affordable KB Gym

This item is worth the money you pay. Solid construction and easy to use. Only downside is that paint chip away more than regular competition bell, but I don't care my bell looks good or not.

great product, very versatile but small damage when it came in

overall the product is great, and exactly what I needed but a few of the adjustable plates came with chips in it. 4.5/5 would be my review 🙂

Awesome kit

I’ve had these for over a year now and they look as good as the day I got them. A great piece of kit for a home gym. I was reluctant at first due to the way they adjust but it’s a small trade off for a great kettlebell. It really doesn’t take that long and we all have rest periods in between sets to do so! Bought two and have no regrets. Highly recommended and will be going with BoS when I upgrade my gym later this year.
