Full Definition
Shoulder plane is the tilt at which the shoulders rotate. At address, the shoulders are perpendicular to the spine angle. Correct backswing: lead shoulder goes down and around, trail shoulder goes up and back. A flat shoulder plane (shoulders turn too horizontally) leads to hooks. A steep shoulder plane (lead shoulder drops too vertically) leads to an over-the-top path. The famous advice to turn your shoulders often causes flat shoulder planes when golfers turn horizontally. GOATY shoulder tracking measures the shoulder plane relative to spine angle.
