Couch Push-Up

“The push-up is more a family of movements than a single exercise. In fact, it is a progression that starts from the horizontal, which is the classic ‘P.E. push-up’ and then, through gradually, incrementally, elevating the feet from the floor to a point where the athlete is eventually in a handstand, becomes the handstand push-up.”
