Set the handles about one foot above the ground. Grab the handles and get yourself into a push up position.
Lower yourself exactly as you would with a normal Pressup, however, let your hands travel slightly further apart as you descend and also at the bottom, go a little lower than your hands. Boy does it hurt.
At the bottom, pause, feel the burn and then slowly push yourself back up. If you can do half the reps you do in a regular Pressup, you are doing amazingly well!
