Full Definition
Thoracic spine (T1-T12) mobility enables shoulder turn without forcing excessive lumbar rotation. Restricted thoracic rotation limits backswing coil, reducing X-factor stretch and power. To compensate, restricted golfers often: over-rotate the lumbar spine (injury risk), shorten the backswing (loss of coil), or tilt excessively (compensatory pattern). Key mobility exercises: thoracic foam rolling, thoracic rotation in quadruped (thread the needle), and thoracic extension over a roller. For every 10° of additional thoracic rotation, you can expect approximately 2-3 mph of additional club head speed from improved coil. GOATY's shoulder turn metrics can identify thoracic restriction patterns.
