Chest Pulse

Begin in the forward prone position. Make sure that you are on a plyometric surface such as a rubber mat or a thick carpeted floor. You are face down on he exercise ball and your knees are in the center of the exercise ball. Your hands should be extended shoulder width apart with your hands on the floor. Walk your hands forward until your ankles or the top of your feet are centered on top of the ball. Your shoulders should be directly over your hands.
Lower your body like as if you were doing a push-up. Instead of pushing up as you would in a traditional push-up, throw your body up so that your hands leave the ground. Throwing your body off of the ball will train your muscles to fire faster.
You can make the exercise more challenging the depth of your push up. Try bending your arms 1/4 way, then 1/2 way and then do short little pulses. You are giving your muscles time to reload before firing again. This will give them the ability to be more explosive.
