The stability ball sit-up is a great way to exercise your abdominals, and puts a new spin on an old exercise.

Starting Position: To begin this exercise, start by sitting on a stability ball. Walk your feet away from the ball until you are lying on the ball with feet wide enough to provide a stable base. Hands can be crossed over chest, or placed on ears, but do not interlock hands behind head, as this often leads to pulling on the head and strain on the neck.

Movement: Similar to a standard sit-up, start by contracting abdominal muscles and lifting your upper body off of the stability ball. Bring your upper body to the upright position, pause and then slowly return to the starting position. Don’t forget to exhale while lifting your upper body up and inhale as you lower yourself back down.
