The key to a healthy shoulder for tennis is to incorporate both flexibility and strength into your weekly routine. Stretching the front of the chest and back of the shoulder can help improve shoulder posture. Strengthening exercises can also help the shoulder tolerate the demands of repetitive arm movement during tennis. Shown below are good exercises for shoulder health.

Corner Stretch

Stand in a corner with your forearms resting on the wall. Keep your elbows below the shoulders. Place one foot forward (alternate foot forward). Lean into the wall, hold for 30 seconds and repeat 4 times.

Sleeper Stretch

Lie on your side with your head resting on the shoulder. Keep the elbow at 90 degrees. Use the opposite hand to push the arm down. Hold for 30 seconds and repeat 4 times.

External Rotation

Place a band around your racquet and a towel roll under your arm. Hold the racquet with your elbow at 90 degrees. Start at your stomach and rotate your hand out. Pause for a 1-2 count and repeat 3 sets of 10 reps.
