When I begin working with a client in their home, the first piece of equipment I tell them to buy is a Swiss ball or Stability Ball.  The presence of the Swiss Ball is everywhere. We find them in large public gyms, private personal training studios, physical therapy offices, corporate board rooms, etc. There are many great benefits of making a stability ball a part of your fitness routine, especially if you are working out at home.
