That large gym ball seemed like a smart purchase at the time, but after a few days of use, it rolled to the corner where it's sat for untouched for months now. Most likely, you're just out of ideas on how to use it. The Total Gym Ball Workout ($10), by Steve Barrett, teaches you dozens of new exercises to try on the ball. The variety not only keeps your routine interesting, but also benefits different muscle groups, thereby making your workout as well-rounded as the ball itself.
