The first time I saw a stability ball was in 1993 when I was volunteering at a physical therapy clinic in Redondo Beach, California. The physical therapist who I was assisting encouraged me to try some balancing exercises on the ball. I was skeptical at first since I’d never seen one at a gym before. So I sat down and it immediately tested my balance. And all I was doing was sitting. She then had me do a few exercises that worked my core (back and abdominal muscles) unlike anything I had done before in the weight room. That was almost 19 years ago. Since then I have incorporated the ball into my workouts and into the workouts of my clients. It’s also a great substitute for a bench and even your chair at work. So get on the ball and pick one up.
