Instructions
Place hands on the floor, slightly wider than shoulder width apart. With straight arms, position your body in a plank like position, with your toes on the floor and legs hip width apart. Hold your core tight and bend your elbows down until your torso touches the floor. Immediately push your body back up as powerfully as possible. As your hands leave the ground rapidly clap hands together and place back to their original position on the floor before your body falls. Repeat.
Tips
If this exercise is too difficult and you would like to incorporate some upper body power exercises, try performing this exercise standing against a wall or alternatively try the deadball slam.
