Lie face down on the floor and place your hands on the ground at a width wider than shoulder width (this exercise can be varied by varying this distance). Hold your torso up at arms length (with the arms locked) in order to assume the starting position. Perform the exercise by slowly lowering yourself downwards by bending your arms until your chest nearly touches the floor. Pause briefly before pressing your body back into the starting position. Repeat for the prescribed number of repetitions.
