Overview
Vinyl-coated cast iron kettlebells sold individually across a 5 to 100 pound range, with a flat bottom for stability and a wide smooth handle for two-hand or one-hand holds.
Yes4All casts these with no seams or welds, which several long-time owners point to as the reason they hold up under heavy swings and drops. The vinyl coating is meant to protect floors and cut down on the metal-on-metal clank of uncoated cast iron.
- Individual kettlebells from 5 to 100 pounds

Questions about the Yes4All K2LK
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
What weight range does the Yes4All kettlebell line cover?
It spans 5 to 100 pounds, sold as individual kettlebells rather than a fixed set.
Does the handle size change between weights?
Yes, reviewers who bought multiple sizes noted the handle gets thicker on heavier kettlebells, which can matter if you have smaller hands.
Can this kettlebell sit flat on the floor?
It has a flat bottom by design, which supports upright storage and exercises that require the bell to rest stably.
