A kettlebell is a piece of exercise equipment that resembles a bowling ball with a suitcase handle attached at the top. Kettlebells are available in many sizes ranging from 8 to 105 pounds. You can do any number of weight-training exercises with kettlebells such as one-arm chest presses, an exercise that strengthens the chest without stressing your rotator cuff the way traditional bench presses might.
