Brit Golf Dad explains what the term 'across the line' means regarding club orientation at the top of the backswing. He outlines how trail arm structure influences shaft angle and demonstrates how turning the right elbow under during transition brings the club back on plane.
An 'across the line' position occurs when the club shaft points to the right of the target line at the top of the backswing.
Extending the trail arm during the backswing loads the trail shoulder complex, creating dynamic potential energy.
To deliver the club on plane, the right elbow must turn under the left arm as the downswing begins.
