An adjustable kettlebell only works if the collar actually holds the load still mid-swing. That locking mechanism is the first thing I check before recommending one to a client.
About the ForgeWeight Adjustable Kettlebell
The ForgeWeight Adjustable Kettlebell replaces a row of fixed kettlebells with one shell and a set of stacking discs. Each disc locks onto the handle shaft and is secured by a stainless steel collar that threads down firmly, so the load stays exactly where you set it through swings, cleans and presses. The handle itself is wrapped in high-density foam, shaped to stay comfortable in the hand even as grip fatigue builds across a longer set. Because the weight is adjustable, one kettlebell covers a wide range of exercises and ability levels, from lighter technique work to heavier conditioning sets. When you are done, the whole unit sits inside its cotton storage sleeve, keeping the handle clean and the discs contained between sessions. It is built for anyone who wants kettlebell training without needing a shelf of separate weights taking up floor space.

Frequently asked questions
How do I change the weight? +
Unscrew the stainless steel locking collar, add or remove discs to the shaft, then thread the collar back down firmly before use.
How do I know the collar is tight enough? +
The collar should sit flush against the top disc with no visible gap and should not turn when you grip and twist the handle by hand.
What weight range does it cover? +
The disc set adjusts the total load from a lighter starting weight up to a heavier combined weight, suiting both technique work and harder conditioning sets.
Is the handle comfortable for longer sets? +
Yes, the high-density foam wrap is shaped to reduce slipping and stay comfortable through extended swings or repeated cleans.
