Position yourself so that the middle of your back is on the ball and your feet flat on the ground, hip width apart. Rest your hands by placing them on your temples. Lift your head, shoulders and upper back drawing in your belly button so as to engage your abdominal muscles. Hold and relax, returning to the start position. Repeat 15 times.
WANT TO MAKE IT HARDER OR EASIER?
To make it harder, you can always hold a weight/s to make the crunch that little bit more challenging. But remember, you should feel no pain in your neck and shoulders so remove the weight should you feel this.
Make sure your chin isn't sitting on top of your chest. Try to imagine a tennis ball in between your chest and chin.
