While many people feel strongly against sit-ups, I think they still have their place especially among athletes. One challenging version of a sit-up using a stability ball starts by lying on the floor with the ball in the overhead position. With your body fully extended, grab either side of the ball with your hands and with a burst of energy, sit-up and bend your knees, bringing them in towards your chest. At the same time, bring the ball from the overhead position on the floor up and over your body in an arching motion, ending by touching the ball to your shins. Then go back to the starting position and repeat. It’s an added challenge if you can keep your feet from resting on the floor by suspending them a few inches off the floor at the start of each repetitions.  Try 10-15 reps for a great abdominal exercise!
