1. Stand with your back to a wall, feet shoulder-width apart, and place the ball between the wall and your lower back.

2. Squat, letting the ball roll along your back, until you are in a "sitting" position with your knees forming a 45 angle. Return to starting position. Repeat.

The Work-Out: Do 1-2 sets of 8-12 repetitions.

Make sure to: Keep your back straight, head up and feet flat on the floor throughout the exercise.
