Rotation under gentle tension, protraction for the shoulder blade, and the first pectoral opening.
Serratus anterior rotates the shoulder blade upward. Weak serratus means the arm runs out of room.
Sitting posture and shoulder position correlate poorly with shoulder pain. Strength and load tolerance correlate far better.
Pain pointed to with one finger on the top of the shoulder, worse reaching across the body, usually sits in the AC joint.
Three couplets · two rounds · twelve minutes · a shoulder that reaches
Hand flat on a table; draw the largest comfortable clock face with the whole arm.

Arms crossed round the chest; reach the hands round the back and let the blades spread.
Easier smaller reach · Harder hold three seconds
Back and arms on the wall; slide the arms up only as far as contact is kept.
Easier arms lower · Harder slide higher
Forearm on the door frame at shoulder height; step through gently and hold.
