Incline push-up (on box)

Place your hands on the edge of a box or elevated surface, slightly wider than shoulder-width apart. Extend your legs behind you, resting on the balls of your feet, creating a straight line from your head to your heels. Lower your chest towards the box by bending your elbows, keeping your body in a straight line. Pause for a moment at the bottom, then push yourself back up to the starting position by straightening your arms. Repeat for the desired number of repetitions.
