Start in a standard push up position, your body aligned from ankles to head.
Lower your body until your chest nearly touches the floor. As you push yourself back up, rotate one side of your body up as you raise the same side arm your toward the ceiling. Keep your glutes and core engaged throughout the movement.
Pause, and return to the starting position and perform another push up. Alternate sides with each rep.
Repeat for the required amount of repetitions for each side.
