What is shoulder internal rotation (resisted)?

Internal rotator strengthening exercise

1. Start by tying a piece of elastic exercise material to a doorknob. You can use surgical tubing or Thera-Band.
2. Stand or sit with your shoulder relaxed and your elbow bent 90 degrees. Your upper arm should rest comfortably against your side. Squeeze a rolled towel between your elbow and your body for comfort. This will help keep your arm at your side.
3. Hold one end of the elastic band in the hand of the painful arm.
4. Slowly rotate your forearm toward your body until it touches your belly. Slowly move it back to where you started.
5. Keep your elbow and upper arm firmly tucked against the towel roll or at your side.
6. Repeat 8 to 12 times.
