This is a great exercise for strengthening the trunk muscles.
Place the stability ball on the upper third of the exercise mat. Make sure that the ball and your feet are on the mat. This gives support and creates a stable position. Place your elbow on the top of the exercise ball with your other hand lightly on the ball for balance. Start with your hip also resting on the exercise ball.
Activate your abdominal and back muscles then lift your hip off of the exercise ball until your body is in a straight line. Keep breathing and hold for 5 to 30 seconds. Lower yourself back to the start position with control. Repeat then switch sides.
