- Lie on your back, and reach your arms rigidly to your side, off the floor. Lift your legs off the floor, and point them, so they are at about a 45-degree angle. Lift your head, so your shoulders are off the floor as well.
- Lift your upper torso off the floor, and bend your knees. You can lean back to make this move harder or come up more to make it easier.
- Slowly lower your upper body back down to the floor, extending the legs. Stop when your back is on the floor, but not your head, shoulders, or legs.
- This completes one rep.
- Complete as many reps with correct form (don't round the back) for 30 seconds.
