Product Details

“As a beginner to kettlebells this product has been a game-changer. The adjustable range lets me progress without buying multiple kettlebells, while maintaining proper form. It’s solid, well-made, and saves a ton of space.” — Robert D

The Adjustable Competition Kettlebell replaces an entire set with 41weight options packed into one tidy shell.

  • True kettlebell shape → unlike bulky competitor adjustables, ours feels just like the real thing. That means you can comfortably perform cleans, snatches, and flows without awkward, wrist-bashing design flaws.
  • Progress at your own pace with 0.5kg & 1kg increment plates (no more awkward, massive jumps).
  • Unlock “in-between” weights you won’t find in regular kettlebells.
  • Save thousands compared to buying a full set.
  • Free up floor space — one compact bell instead of a whole rack.

One bell to rule them all — beginner to advanced.


Why Kettlebells?


Because kettlebells do what bars and dumbbells can’t:

  • Strength + cardio in one go  build muscle and burn calories without swapping equipment.
  • Real-world strength  training that carries over to sports, daily life, and even hauling in your groceries.
  • Total-body efficiency  work multiple muscle groups at once, not just one at a time.
  • Compact powerhouse  a full gym’s worth of versatility in a fraction of the space.

They’re the overachievers of the fitness world — and now you only need one.

Product Details


Grab your kettlebell training by the horns with the Adjustable Kettlebell: now available in blue, purple, and yellow! This Adjustable Kettlebell can range from 12kg-32kg in 0.5kg increments, so you save money and space - no matter what exercises you (Turkish) get up to. Crafted like a competition-style kettlebell, the steel shell and iron weight plates keep the internal workings secure, so you don't have to worry about rattles and damage.

With 41 weight increments in one kettlebell with the expansion pack, this bad boy replaces a full kettlebell set and saves over $700 compared to purchasing standalone competition kettlebells.

The 20.5kg base includes the 12kg shell with 8.5kg of weight plates (1x 3kg, 2x 2kg, 1x 1kg & 1x 0.5kg), so you get 18 different increments with just the base model — yes, even that pesky 13kg! Add the 13kg expansion pack plates (2x 4kg, 1x 3kg, 1x 2 kg) for even more range.

    Have bells will travel

    Bells of Steel kettlebells are a great product. I have a solid partial set of Bells of Steel singles and doubles in my garage gym doubles 12 and 16's, singles 20, 24, 28, 32 KG, and I love them. But I also wanted the flexibility to take my training with me when I travel or when I want to work out at the beach or in the park. So I picked up a set of BS adjustables and built a dedicated storage system for the plates and tools. Now I can load the two bells and the storage unit right into my trunk and take my gym anywhere. The storage setup even doubles as a super-loaded suitcase carry implement. I would love to add doubles to my other singles, but the cost is just too much. I am hoping BS will offer some nice deals for Black Friday. I would love to get another 20KB bell for my garage gym.

    They're everything everybody says about them.

    These kettlebells are built like a tank. They're super convenient, space-saving and affordable for all the weight option you get. Also the fit and finish is significantly better than the other offerings out there. I’d recommend getting (at least) two so you can always have a light-medium and a heavy KB ready for whatever your workout throws at you. And Bells of Steel’s customer service is always prompt and super helpful.

    Great kettlebell

    Well built with no cheap plastic parts. The weights don’t move around inside the shell at all. The 2 parts of the shell were pretty stuck together when i got it. I had to jam a knife between them with a hammer to budge it open.
