Stuart Cartwright from Good Golf Coaching reveals how trail forearm rotation controls shaft plane and shallowing in the golf downswing. By delaying trail forearm external rotation until the top of the backswing, golfers can naturally shallow the shaft without artificial manipulations. The lesson includes clear visual demonstrations and a step-by-step transition drill.
Keep the trail arm in internal rotation during the takeaway to keep the club head and face in position without fanning open.
Delay trail forearm external rotation until the top 15% of the backswing to naturally shallow the shaft plane.
Pulling down on the club handle after late trail arm external rotation naturally delivers the shaft on an inside path.
Drive the trail hip and trail shoulder forward through impact to rotate through the shot and prevent pushing the ball right.
