Get into a push up position with your body straight and arms extended. Your hands should be in line and wider than shoulder width. Your feet should be about hip width apart and on your toes. Make sure your head is down, with your eyes pointed to the ground.
Drop your entire body down toward the floor as one unit by bending at the elbows and opening up your chest. Once your body is a few inches off the ground, drive through your hands, keeping your body flat, until your arms are extended.
Repeat for given reps.
