Add these four exercises to your training to improve shoulder stability and increase scapular (upper back) strength.
Swiss Ball Y1 of 5
Lie on a Swiss ball with your back flat and your chest off the ball. Your arms should hang down (thumbs forward). Glide your shoulder blades back and down, and lift your arms till you form a Y. Return to the starting position.
Swiss Ball W2 of 5
Same starting position as for the Y, but bend your arms and squeeze your elbows in toward your ribs. Rotate your arms toward the ceiling, squeezing your shoulder blades together. Return to the starting position.
Swiss-Ball T3 of 5
Same starting position as for the Y, but your palms should face forward. Pull your shoulder blades in toward your spine and extend your arms straight to the sides to create a T with your torso. Return to the starting position.
Swiss Ball L4 of 5
Same starting position as for the Y, except your palms should face behind you. Bend your elbows so that your upper arms create a pair of L's. Rotate your arms so your palms face the floor. Retrace the pattern to the starting position.
