With a sturdy incline setup give yourself a wide stance with your legs. Place one arm in front of you supporting your weight on the floor. The pushing arm will operate exactly as it does in a normal pushup. Shoulders should be active and supporting the push arm. Elbow travels back and to the side without flaring out at any point in the movement. Lower yourself until the ground touches your chest. As you lower yourself down maintain a rigid body-line to prevent any twisting.
