What muscles cause internal rotation of shoulder?
The teres major provides internal rotation, extension, and adduction of the shoulder; it’s considered a fusiform muscle. The subscapularis muscle internally rotates the humerus; the upper portion of the muscle influences abduction, while the lower area influences adduction. It is considered a multipennate muscle.

What muscle internally rotates hip?

What muscles does external rotation work?
The external rotation exercise targets the infraspinatus muscle which is a very important muscle of the rotator cuff. The rotator cuff muscles help to provide some stability for the shoulder joint. The main function of the infraspinatus muscle is to rotate the humerus, or long arm bone, away from the body.
