Kettlebell weights provide an easy-to-maneuver design and ability to rotate fluidly in ways that regular hand weights cannot, boosting your cardio workouts, toning muscles, and increasing endurance. Made from solid cast iron with no fillers, this 1.2" handle, vinyl coated, flat bottom, single-piece casted kettlebell is less likely to break than other giryas made from multiple parts, making it crack and rust resistant.
