Full Definition
Shoulder turn amount is the angular distance the shoulder line travels from address to the top of the backswing. Standard reference: 90 degrees (lead shoulder points at the ball position at the top of the swing). Less than 75 degrees: restricted coil, reduced X-factor potential, power loss. More than 105 degrees: often accompanied by excessive lateral sway or loss of posture. Factors affecting shoulder turn: thoracic mobility (limiting factor for most golfers over 40), hip mobility (resisting the shoulder turn), and posture maintenance (slumped posture reduces rotation range). Tour player averages: male players typically show 90-100 degrees, female tour players 80-95 degrees. Every 10 degrees of additional shoulder turn (achieved correctly without sway) can add 5-8 mph of potential club head speed. GOATY tracks shoulder turn in the backswing as part of the ENGINE gate sequencing metrics.
