Designed as a safe alternative to traditional steel kettlebells, the Champion Sports 18 lb Rhino® Kettlebell is made from safe rubber that will not damage gym floors if dropped. This rubber kettlebell features a smooth, molded handle, providing you with a steady grip during your workout and offering exceptional stability. This kettlebell is the same diameter as other bells of different weights, meaning you can maintain proper form even when increasing or decreasing the weight you are using.
