Here is the standard stability ball crunch. One that I'm sure a lot of you have done before but still a very effective one if done correctly. It all depends on the position of the ball under your back. The further up your back the ball is the easier the crunch will be. The nearer your hips the ball is the harder it will be as more of you will be leaning off the ball. Keep the core muscles 'engaged' throughout the crunches, that is pull your tummy button in toward your spine and tense. And hold a medicine ball or small weight to increase the difficulty if you need to.
You should feel these after 3 sets of 15 reps. If you cant, change the position of the ball to make it harder!
