Shoulder External Rotation | 3D Anatomy
Stand, hold the cable (or resistance band), bend the elbow upward to 90 degrees and hold your upper arm at the side of the body. Place the body such that the cable pulls sideways toward the inactive arm.
Anatomical analysis:
The target muscles are the shoulder external rotators. Strengthening the muscles that support your shoulder will help keep your shoulder joint stable.
In red we can see how the infraspinatus muscle externally rotates the humerus.
In pink we see the posterior deltoid and teres minor that assist in shoulder external rotation.
Our goal is to help you understand better how the body move, enhance your understanding and transfer that knowledge to your clients.
