Strengthening exercises are as important for tennis players as they are for any other "overhead" athlete.

The following  are examples of common strengthening exercises that can be prescribed by a physical therapist.

They are not intended to be a replacement for treatment. 

For more customized exercises for your specific needs consult with a physical therapist.

Rotator Cuff

External Rotation strengthening

Helps with backhand and serves. May protect against elbow tendonitis. 

Start Position for External Rotation

Using resistance band tied to a door knob, stand with arm at your side, elbow bent 90 degrees. Place a small towel roll under your arm. Hold band as shown and slowly rotate arm outward while maintaining 90 degrees at the elbow.

End Position for External Rotation.

Pause at the end point for a second. Slowly return to start position. Repeat 8-12x for 2-3 sets. Do this exercise 2-3 time per week.

Forearm Strengthening

Forearm Suppination/Pronation

Helps with racquet control during forehand/backhand

Using a hammer or light dumbbell held with the one end in your hand, rest forearm on a table and slowly rotate the dumbbell/hammer back and forth. Pause briefly at each extreme. Perform 2-3 sets of 8-12 reps, 2-3 times per week.

Resisted Forearm Suppination/Pronation

Scapular Stabilizers
Lower Trapezius
Helps with stabilization of the shoulder during all movement and protects the rotator cuff from excessive strain. May protect against impingement at the shoulder.

While lying on the floor with a pillow under your trunk, place both arms over head forming  a "Y". Raise both arms away from the floor towards ceiling. Feel your shoulder blades pinch together slightly. Pause and return to start position. Repeat 8-12 times. Perform 2 sets, 2-3 times per week.
Beginners might want to start with one arm at a time. More advanced exercise can add light weight and lay over a therapy ball or bench.
