Perfect Ab crunch

- Lie down with your back flat on the floor. Place you hands behind your head as illustrated above or on your chest.
- Lift your upper body a third of the way to your knees as above (you may feel your abdominals contracting)
- As you come up slowly exhale. When you have reached the top of the movement keep this position for a few seconds breathing in and out. Then lower yourself down and exhale.
- You can repeat this process as many times as you like. 20-30 times a day should be adequate.
Tips
- It is not good to do too many crunches as you may become too tired and not get the full effect of the abdominal workout.
- Your neck should be properly aligned when lifting yourself up. One way to do this would be to put your fist under your chin to keep it from moving.
