Kettlebell training develops strength, power, endurance and balance. Working out with kettlebells will sculpt and tone the entire body because lifting and controlling a kettlebell forces the entire body, and specifically the core, to contract as a group, building both strength and stability at the same time. Features: Helps develop strength, power, endurance and balance. Protective vinyl shell to prevent wear and tear. Great option for getting a whole body workout in a short time.
