Stand up straight with one leg: It will be easier to lift your arm sideways. 4. Four-point balance on the ball: keep this action on the ball 1 sec -2 sec. 5, three points on the ball: more difficult! 6. Two points on the ball: When you finish this action, you will feel that your gluteal muscles and bony buttocks need great strength and skills to maintain this action. Practice against the wall until you can finish this action. 7. "Debut": You can keep your balance and look straight ahead to take pictures of you. 8.
