Other Muscles at Play
Objectives
Strengthens the posterior shoulder and trunk rotators to support powerful, well-organized rotational control.
Trains steady stabilization of the shoulder and scapula to keep the arm clear, connected, and precise.
Builds coordinated, integrated control of the core muscles to anchor the movement with stability and ease.
Targets the posterior muscles involved in rotational control, especially those that connect the scapula and shoulder, to create stronger, more integrated support through the upper back and shoulder complex.
Focus on breathing to synchronize the movement.
