These movements are not just about shoulder external rotation. It is about teaching multiple joints and tissues to communicate under load.
The rotator cuff, scapula, shoulder capsule, and nervous system all have a role to play.
When those internal signals improve, movement becomes more efficient, more resilient, and more adaptable.
Better shoulder health is rarely built through one muscle.
It is built through better communication between the structures that create movement.
