Available in multiple sizes, Troy Barbell’s Cast Iron Kettlebells are intended to increase strength, agility, endurance and balance. Shaped like a large kettle without a spout, Troy's cast iron kettlebell is about the size of a cannonball and is attached with a larger, ergonomically rounded handle. Troy Barbell’s kettlebells are perfectly suited for single or dual hand core body movements. A quality, baked enamel finish creates less friction when changing hand positions on transitional lifts. Challenging both the muscular and cardiovascular system with dynamic, total-body movements, kettlebells deliver extreme all-around fitness. Kettlebell lifting has been nationally recognized and played throughout the world for decades and has greatly increased in popularity the last few years. Kettlebell sizes range from 10 pounds to 70 pounds.
