Sit On Ball
Technique
Sit on the exercise ball with your feet placed on the floor. Sit tall, make yourself as tall as possible. Relax your shoulders, lower and drag pull them back slightly as you push your chest forward. Sit on the ball and tighten the abdominal muscles by pulling your belly button in towards the spine, as if to parry a boxing bang. You activate the abdominal muscles automatically when you sit on the ball, to keep the balance.
Tips
Try using the ball as a chair sometimes and see how it feels, sit on it when you talk on the phone or watch TV.
Alternatives
Try lifting your feet alternately to make the exercise harder or sit on the ball and make small circles beneath, to train the mobility of the lumbar spine. You can also make the exercise tougher by involving the upper body, keep your arms stretched in front of you, use the muscles on back of the shoulders and do rowing, squeeze your shoulder blades together.
