Lie prone on floor with hands slightly wider than shoulder width. Raise body up off floor by extending arms with body straight.
Keeping body straight, lower body to floor by bending arms. Push body up until arms are extended. Continue lifting body further up by pushing shoulders infront of chest. Repeat.
Both upper and lower body must be kept straight throughout movement. See similar Push-up exercises targeting Pectoralis Major.
Resistance can be reduced by performing push-ups with knees bent on floor or placing hands on elevated horizontal bar, in between narrow doorway, or edge of elevated surface.
For greater challenge, perform plyometric version for more power.
