Latissimus, Trapezius, Shoulders, Chest, Triceps, Back
Place your hands on an elevated surface—such a box or bench—with your arms straight and your hands directly below your shoulders.
Walk your legs out behind you until you’re in a pushup position. Your body should form a straight line from your head to your heels.
Brace your abdominals—as if you were about to be punched in the gut—and squeeze your glutes. Maintain these contractions for the duration of the exercise.
Lower your body until your chest nearly touches the box of bench. Don’t let your hips sag at any point. Pause at the bottom, and then push yourself back to the stating position as quickly as possible.
