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


Overview

The Adjustable Competition Kettlebell is a precision-engineered strength tool designed for lifters who want the full weight range of an entire kettlebell set in one beautiful bell—without sacrificing space, feel, or durability. Talk about an overachiever.

Built with a steel shell, iron plates, 0.5 kg micro-loading, true competition shape and size, and up to 41 weight intervals in one bell, it delivers the exact performance of fixed kettlebells in a modular, space-saving format.

Unlike quick-adjust dial systems that rely on plastic components and age like milk, this bell prioritizes stability, longevity, and premium commercial-grade construction, making it the ideal choice for serious home gym owners, minimalist training spaces, and athletes who demand uncompromising performance, no matter what they (Turkish) get up to.

IMPORTANT: The Adjustable Kettlebell is a fantastic tool, but it is not recommended when a fast transition of sizes is needed since changing the weights takes 1-2 minutes. If you need two different weights for swings and overhead work, we recommend getting two adjustable kettlebells for sale — you save 10% when you buy a pair.


Who It's For

Beginners
Micro-loading and optional lighter-start add-ons make early progression smoother and safer. Perfect for learning kettlebell fundamentals with proper form.

Intermediate Lifters
41 weight settings enable continuous progression for full-body strength training. Switch between swings, cleans, presses, squats, and accessory work without needing multiple bells.

Advanced Athletes
True competition sizing, balanced geometry, and 0.5 kg precision jumps allow refined technique, double-bell programming, and plateau breaking—ideal for serious kettlebell practitioners.

Small-Space Home Gyms & Apartments
Replace an entire rack of kettlebells in the footprint of a single bell. Highly portable, compact, and quiet enough for multi-unit living.

Coaches & Personal Trainers
While not recommended for classes, the wide adjustability supports multiple clients with different strength levels using a single piece of equipment.


Premium Build & Materials

Every component is chosen for commercial durability:

  • Steel Shell: maintains perfect geometry across all weights
  • Iron Plates: machined to tight tolerances for consistent balance
  • Steel-on-Steel Locking System: no fragile plastic, no gimmicks
  • Competition Handle (35 mm): consistent grip feel at any load
  • Balanced Bell Cavity: ensures predictable swing paths and smooth transitions

The result is an adjustable system that feels indistinguishable from a fixed kettlebell—something customers repeatedly confirm in reviews.


Weight Range & Micro-Loading

With 41 possible weight settings from 12–32 kg, the Adjustable Competition Kettlebell gives you full control over your progression.

Why Micro-Loading Matters
Most adjustable kettlebells jump in 1–2 kg increments (or larger), forcing lifters into uncomfortable leaps. This bell offers 0.5 kg micro-loading, allowing:

  • Smoother strength progression
  • Safer jumps for beginners
  • More precise overload for advanced athletes
  • Fine-tuned programming for kettlebell complexes
  • Easier weight matching during unilateral accessory work

This is one of the product's biggest advantages over the competition.


Plastic Bottom Add-On: Lighter Weights, More Versatility

Many users require access to lighter ranges for curls, shoulder prehab, warm-ups, or accessory training. The Plastic Bottom Add-On solves this by reducing the bell to a 9 kg base, with plate configurations enabling 9.5–11.5 kg. Perfect for:

  • Single-arm curls
  • Preacher curls
  • Shoulder rehab/prehab
  • Beginners learning kettlebell technique
  • Accessory isolation movements

It essentially expands the product downward, offering a true full-range kettlebell system from 9–32 kg.


Stability & Internal Movement

Many competitor bells rattle and shake, creating instability and distraction during exercise. This bell minimizes shifting through:

  • Precision-cut iron plates
  • Tight internal fitment
  • A secure locking system
  • A stable cavity shape engineered to reduce noise

Most users describe the feel as "solid," "stable," and "built like a tank."

How It Compares to Other Adjustable Kettlebells
Feature Adjustable Competition KB Typical Adjustable KBs
Weight Range 12–32 kg (expandable to 9–32 kg w/ add-on) 16–24 kg or limited ranges
Increment Size 0.5 kg micro-loading 1–2 kg jumps or fixed stops
Construction All-metal steel + iron Often uses plastic components
Geometry True competition standards Varies; many non-standard shapes
Adjustment System Secure steel-on-steel, durable Fast-but-fragile dial systems
Feel During Use Matches fixed kettlebells Often unbalanced or hollow-feeling
Space Requirements Replaces 41 bells Replaces fewer bells
Portability Easy to transport; modular Often bulky or awkward

This positions the product as a premium, competition-grade adjustable kettlebell system—built for real training, not just convenience.


Adjustment Experience

The bell is designed for durability over speed.

  • Typical adjustment time: 60–90 seconds
  • Optimized for safety, stability, and longevity—not fast but fragile mechanisms
  • Easy learning curve after first few uses
  • Clear plate stacking and labeling for intuitive weight setup

A short setup between sets is normal—and ensures the bell lasts for years under heavy use.


Competition Geometry & Feel

This is where it separates itself from dial-adjustable systems.

  • Fixed-width 35 mm handle ensures consistent grip familiarity
  • Standardized window size keeps movements smooth
  • Uniform bell shape mimics fixed competition kettlebells across all weights
  • Maintains predictable pull paths in snatches, swings, cleans, Turkish get-ups, push presses, and jerks

Lifters repeatedly confirm that it "feels like a real comp bell," a key differentiator from Bowflex-style or cast-iron adjustable alternatives.


Versatility & Training Applications

The Adjustable Competition Kettlebell supports every major kettlebell movement:

  • Two-hand and single-hand swings
  • Cleans & clean variations
  • Snatches
  • Turkish get-ups
  • Presses, push presses, & jerks
  • Goblet squats & front-loaded squats
  • Deadlifts, rows, & high pulls
  • Lunges & step-ups
  • Windmills & core anti-rotation work
  • Conditioning complexes
  • Accessories with lighter weight ranges (via plastic bottom add-on)

You effectively replace an entire progression system with one modular tool.


Space & Portability
  • Fits easily in apartments, condos, small home gyms
  • Travels easily (remove plates and pack flat)
  • Ideal for lifters who want serious training without dedicated storage racks
  • Minimal noise—reviewers consistently describe it as "quiet enough for apartments"

Warranty & Support

Your Adjustable Competition Kettlebell is backed by:

  • Lifetime shell warranty
  • Responsive, top-rated customer service
  • Clear online setup support
  • A community of lifters who stand behind the product

Built for performance. Backed for life.

    Expensive, but worth it kettlebells

    I have started working out with my set of 12-20.5 kg kettlebells, and I am very happy with them. The KBs are pretty solid, they don't clank when moved. They also feel good in my hands for my various carries and swings. They are a bit pricey, but so far they are worth the price. It's not hard to change the weights on the KB, but its also not all that quick. I am especially digging the blue coating.

    12kg-32kg adjustable competition kettlebells V2.0

    I received the kettle bells within a decent amount of time as expected.

    I weighed the kettlebells & all of the individual plates on a scale that is certified by the division of weights & measures to be accurate for filling propane bottles & the kettlebells are pretty accurate but do run just a tiny tiny bit heavy.

    As expected for being a cast product the fit & finish is really decent & the only con is that for the ones I received the handles still needed to be filed & sanded as the ones that I received had a little smoothing that needed to be finished & had a fair amount of oxidation & little pitting on the handles but other than that these are excellent kettlebells & catching them on sale. It was a fair price for this type of setup.

    Donald, thank you for the thoughtful and detailed review. We appreciate you taking the time to weigh everything out and give such a thorough breakdown of the 12kg to 32kg Adjustable Competition Kettlebell V2.0.

    Glad to hear the shipping time met expectations and that the plates came in very close to spec. A tiny bit heavy is definitely better than light when it comes to strength training. It is also great to hear you are happy with the overall fit and finish, especially for a cast product.

    We also appreciate you calling out the handle finish. Feedback like that helps us continue refining the details that matter to lifters.

    We are pumped you snagged them on sale and that they are delivering excellent value for your setup. Time to put those bells to work.

    Yours in strength,

    The B.o.S. Crew. 💪

    True to weight, good grip with small footprint

    Surprisingly solid and seamless, can’t even tell it’s adjustable.

    True to weight, solid feel, and a small footprint is exactly what we were going for with the Adjustable Kettlebell. And the fact that it feels seamless enough that you cannot even tell it is adjustable? That is a huge win.

    Big versatility without taking over your space is what home gym dreams are made of. Appreciate you trusting us with your training.

    Yours in strength,
    The B.o.S. Crew.

    Solid!

    Been using my new kettlebell almost every day since I got it and this thing is a tank! It may not be the fastest at changing up the weight, but it’s plenty fast for the work I do and still more convenient than having to have multiple pieces taking up space. I wouldn’t trade how solid it is for quicker weight changes.
