When your arms are lifted off of the floor, your body is forced to use its back muscles rather than arms to lift your body.
- Start on your stomach, flex your feet, and engage your toes on the floor. Keep abs lifted and ribs pressed inward. Place arms wider than shoulder width, palms facing down and shoulder blades pressed down and back.
- Contract back muscles to pull up, rotating shoulders around, squeezing scapulas together, and facing palms outward. Be sure to keep the chin and neck pulled inwards and back.
- Hold one second and release back down to the floor.
- Complete 15 reps, and repeat one more set.
