Physio Ball L
Objective: To improve shoulder stability and rotator cuff and scapular strength. Technique: Lie prone on top of the ball with your back flat and your chest clearing off the ball. Create a 90-degree angle with your arms. Then squeeze your shoulder blades together to raise your upper arms so that they are 90 degrees to your torso, creating a pair of Ls. Hold that position then externally rotate your upper arms so that the backs of your hands reach toward the ceiling then return slowly to the starting position.
