Internal shoulder rotation is counterclockwise upper arm rotation.



In picture below Serena Williams is trying to hit hard FH winner. Here is original video http://www.youtube.com/watch?v=BJg5cWEviZo.



Her main armís motions around contact are:
1. Arm flexion.
2. Internal shoulder rotation.
3. Forearm pronation.
4. Wrist ulnar deviation.
