This is a great exercise to strengthen the upper arms and shoulders.
- Sit upright with perfect posture on the ball. Have both elbows bent at 90 degrees while holding the band in both hands. The band should pass over the top of your head.
- Straighten your right arm, while holding the left arm completely still and not allowing your shoulders to shrug.
- Do ten to twelve repetitions, then return to the starting position. Relax your arms briefly. Repeat the exercise sequence once or twice.
