FYF - Prone Shoulder Mid Trap (aka, Ts)
With any movement, you need to identify the purpose! Your technique should then match that purpose to ensure success.
For this valuable shoulder movement,
The purpose is ... Activate and strengthen the scapula adductor that facilitates the upper 50% of shoulder motion. Only the middle fibers of the trapezius muscle can balance the more powerful force of gravity and the gravity assisted muscles. Get it right and you'll counteract the stiffness of lats and pecs. Get it wrong and deal with poor scapular alignment that makes posture and movement more difficult to do well.
The technique fault is... Inadvertent initiation abduction with downward rotation (you can tell cuz is hands finished closer to his butt than his head at end range).
The technique fix is... Guide the movement with tactile/ verbal/ visual cues to ensure he is finishing his motion with his arms slightly above 90° to his torso.
Look out for the film room session for an explanation of teaching.
