2) Shoulder circles in lateral position
Lie on your right side with your legs bent at a 90-degree angle in front of your body. Extend both arms forward, left hand resting on the right. Now tense your abdominal muscles and bring your left arm in a large semicircular motion behind your body and back again.
Be sure to keep your arm and your shoulder on the lower side of the body as close to the floor as possible.
Do six repetitions on the right side, then six more on the left.
