Bodyweight Incline Knee Push Up

Start by placing two boxes (or one) on the floor, about shoulder-width apart. Position yourself in a plank position with your hands on top of the box, keeping your arms straight. Put your knees on the floor. Engage your core and lower your body towards the floor by bending your arms, until your chest nearly touches the box. Push your body back up to the starting position, straightening your arms and engaging your chest, triceps and shoulders.
