Place your hands on the exercise ball. Bring one knee onto the ball and once you have found your balance bring your other knee up onto the ball. Start by holding this position for 15-30 seconds. After you have comfortably mastered the balance for 30 seconds, you can increase difficulty by lengthening the time.
Here you have access to hundreds of exercises with detailed instructions and pictures for each exercise step.
If you are registered you can add these exercises to your personal workout program and create an exercise plan that you can print. And, of course, you can change the program any time as you progress.
You just have to register (it's free) or login!
