Lying Cable Crunch

Lie flat on your back on the floor, facing away from a low cable, with the rope attachment held behind your head. Crunch your shoulder blades up off the floor by curling your ribs toward your hips, keeping the cable path close to your body rather than pulling with your arms. Unlike a kneeling cable crunch, your hips stay planted the whole time — only your upper spine moves. Lower back down slowly enough to feel the stretch return before your next rep. Keep your elbows wide and fixed relative to your head so the pull comes through your torso, not your shoulders.
