Benefits of the Adjustable Kettlebell

  • 41 SIZES IN 1 KETTLEBELL
    This adjustable kettlebell used to be an all-in-one 32kg package. This upgraded version now features a base model with an optional expansion pack, so you can start light and upgrade later. 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) to have a WHOPPING 41 increments, which is enough range for most to last a lifetime of kettlebell training.
  • REPLACES +8 KETTLEBELLS
    As you progress in strength and skill, you’ll need more kettlebells, and more room to store them. Luckily, this adjustable kettlebell replaces an ENTIRE set, as it can weigh anywhere from 12kg to 32kg with the expansion pack. Its weight range makes it the perfect option for home gym enthusiasts, small fitness studios and others who are tight on space. Just store it in a corner or under the stairs but if you’re a real-deal Beller, you know it’s best admired atop your fireplace mantle in the glow of a smoldering fire, as you drink vodka straight from the bottle like a hardened Girevik of old.
  • SAVES OVER $700
    Buying enough competition kettlebells to replace this adjustable kettlebell would tally up to over $1,000 and that’s BEFORE adding the shipping fees…. talk about a kick in the bells. And unless you want them strewn across your floor, you might also want an Interchangeable Weight Rack to store them on. Clearly, costs can add up fast. But when you invest in an adjustable kettlebell instead, you’ll save yourself at least $700 — your wallet (and your nether regions) will thank you.

Real Kettlebell Feeling

If you’re a serious kettlebell’er, you know that you should practice like you play. This adjustable kettlebell closely matches the feeling and dimensions of pro-grade kettlebells — 35mm handle, competition-sized shell, and 11″ height — so you can master your swings, cleans & presses in sport-specific fashion (vintage leotard not included)🤸🏻‍♀️

Simple To Adjust

Adjusting the weights in your adjustable kettlebell takes only 1-2 minutes. Use the included Allen key to undo the bottom screw, remove the bottom part of the shell, loosen the nut using the included hex nut wrench, and swap whatever plates you need. Reverse these steps to reassemble, and voilà! You’re ready to swing into your next set.

Easy To Micro-Load

Our competitors rarely offer plates smaller than 2kg, so you typically can’t do 13kg or 31kg with theirs. But the base model of the B.o.S adjustable kettlebell has a 0.5kg AND 1kg plate, so you can micro-load every step of the way. And when 2kg increases become too hard, you can add as little as 0.5kg for a more manageable workload.

Highly Portable

Kettlebells are compact, so you can take them almost anywhere. But an adjustable kettlebell is on a whole nother’ level. With it, you can get an insanely scalable workout anywhere, anytime — at the outdoor fitness park, deep in the woods or at your kid’s soccer game. And while they’re scoring goals on the field, you’ll be scoring gainzzz in your fitness 💪🏻

Frequently Asked Questions

  • What is the weight of the adjustable kettlebell?

    With the expansion pack, the adjustable kettlebell can weigh between 12kg (empty shell) to 32kg (fully loaded) in 0.5kg increments.

  • What are the dimensions of the adjustable kettlebell?

    The dimensions of the adjustable kettlebell are:

    • 35mm handle
    • 11″ height
    • 8.25″ shell diameter
    • 12-20.5kg range (20.5 base model)
    • 12-32kg range (with expansion pack)
    • Adjustable in 0.5kg increments
  • What is the finish on the adjustable kettlebell?

    The finish on the adjustable kettlebell is a smooth & glossy powder coat, offering a premium feel. This finish is an improvement compared to our first version, and is better than the finish on the adjustable kettlebells of most of our competitors.

  • How does an adjustable kettlebell work?

    The Bells of Steel adjustable kettlebell works by having its weight plates loaded on a center rod inside a steel shell. The weight adjustments are done internally (inside the shell), without changing the shell’s size.

  • How to adjust an adjustable kettlebell?

    To adjust this adjustable kettlebell, use the included Allen key to undo the bottom screw and remove the bottom part of the shell. Loosen the nut using the included hex nut wrench, and swap whatever plates you need. Reverse these steps to reassemble the adjustable kettlebell.

  • How long does it take to change the weight of an adjustable kettlebell?

    It only takes 1-2 minutes to change the weight of this adjustable kettlebell. Many kettlebell users find that this downtime helps them recover and improves their focus for the next set.

  • How many different weights can you make using an adjustable kettlebell?

    You can make 41 different weight increments using this adjustable kettlebell: 12kg, 12.5, 13, 13.5, 14, 14.5, 15, 15.5, 16, 16.5, 17, 17.5, 18, 18.5, 19, 19.5, 20, 20.5, 21, 21.5, 22, 22.5, 23, 23.5, 24, 24.5, 25, 25.5, 26, 26.5, 27, 27.5, 28, 28.5, 29, 29.5, 30, 30.5, 31, 31.5, and 32kg.

    *You’ll technically have 33.5kg worth of weight if you buy the expansion pack but the same 32kg limit still applies, just like the first version of our adjustable kettlebell. This ensures that it closely aligns with the height of competition kettlebells.

  • How to stop the weights from rattling in an adjustable kettlebell?

    If you find your adjustable kettlebell rattles in use, you’ll need to buy two separate M24 nuts for this added fix. Screw one nut onto the threaded center column, then add a second nut in direct contact and lock them by counter-screwing them together. Add your plates, then add two more nuts and counter-screw them together as well. Please note that this will make it difficult to loosen the nuts and weight changes will take longer. For a detailed explanation of this, check out this timestamp on Mark Wildman’s Youtube video.

  • How to open the stuck shell of an adjustable kettlebell?

    To open the stuck shell of an adjustable kettlebell, grab a hammer and lay the adjustable kettlebell on something soft like a folded towel. Insert the Allen key into the bottom screw and while holding it in place, firmly strike the long part of the Allen key with the hammer until the screw physically turns. Then, you can loosen the screw with the key by hand to open the stuck shell.

  • How is this adjustable kettlebell different than the first B.o.S. version?

    Here’s how this adjustable kettlebell differs from our first version:

    • It’s sold as two separate items (20.5kg base model & 13kg expansion pack), instead of an all-in-one package.
    • It includes 1kg & 0.5kg weight plates, instead of only having 2kg, 3kg & 4kg plates.
    • It has an upgraded finish that is smoother and glossier, when compared to our original version and the adjustable kettlebells of our competitors.
    • It features our snazzy Bells of Steel logo on the shell.
  • How does the weight distribution feel in an adjustable kettlebell?

    There’s a slight difference in the weight distribution of an adjustable kettlebell that makes it feel more like a cast kettlebell. However, this is rarely enough of an issue that it outweighs the adjustable kettlebell’s benefits.

  • What is included with the 20.5kg base model of the adjustable kettlebell?

    The 20.5kg base model of the adjustable kettlebell includes:

    • 12kg shell
    • 8.5kg of weight plates (1x 3kg, 2x 2kg, 1x 1kg & 1x 0.5kg)

  • My Fitness Goal Is: get swole

works great when put together, takes 5 min to change out

works great when put together, takes 5 min to change out. only issue is that if I do not really crank the bolt down tight, the plates will start to spin during movements

Hi Steven, Thank you for reviewing our adjustable kettlebell. We are so happy that you find it easy to adjust and put together. We will see about making the plates less spin able in the future and thank you for your feedback. Sincerely, Marcus & the BoS team

  • My Fitness Goal Is: I'm mainly strength train with barbells, but use kettlebells for mobility and conditioning.

Don't hesitate to purchase!

Like me, you have probably seen several adjustable kettlebells that were oddly shaped and way too light. Finally someone did it right. I was worried that being internally plate loaded would make the bell feel unbalanced, but it has the feel of a solid bell. It only takes a minute or two to change weights with the included wrenches, and there is no rattling when the bolts are snugged. I put this bell through the paces of swings, snatches, and flow workouts with zero problems. I've been a kettlebell user for over 10 years and would highly recommend this product.

  • My Fitness Goal Is: Staying strong to fight Father Time

Excellent product

Love this kettlebell! Costs Less than kettlebell kings, but said to be the same. I almost bought a used kb kings adjustable bell right around the time I got this! I have an assortment of 16-20kg bells, but this allows me to do doubles with a competition bell I have, and allows challenging weights as a single. Keeps my crowded garage from pinching my fitness setup. The best product you could buy for fitness & kb training. You won’t be disappointed!

Well engineered, good quality. Excellent for dialing just the right weight. The two nut design works very well to keep the plates centered and locked in place inside the shell. Customer service fantastic in working out shipping over the ocean. Thanks Bells of Steel!
