Lie on the ground with your arms fully extended over your shoulders, legs bent and your feet, legs, and back firmly planted on the ground. Wrap a band around a power rack or pole at the height of your hands.
Using an overhand grip, exhale and curl your body forward by raising your head and upper back off the ground. Maintain the position of your arms and do not allow them to help with the movement.
Continue to curl your body forward as far as you can while still keeping your lower back firmly planted on the ground, stopping lower than you would in a sit up.
While continuing to keep your arms still and at the level of your shoulders, inhale and lower your body to the ground, returning to the starting position.
