Crunches

- Start on your back, with your knees bent and feet on the floor. Your hands will be behind your head.
- Using your core, bring your head up toward the ceiling.
- Control the movement back down to return to the starting position.
- Don't think of curling your head in, rather bring your head up. This will protect your neck and promote proper form.
- Keep your lower back on the floor.
- If you can, keep your elbows extended out to the side. Do not aim them toward your knees.
