Complete your backswing with body, not bending arms
Improve body movement instead of completing the swing by bending the arms. To maintain the letter Y, possible adjustments include slightly raising the left heel, moving the knee toward the ball, turning the hips more, or moving the pelvis toward the target. Without sufficient body movement, the swing will be completed by bending the arms.

Aimed at players who lack flexibility and hit a point where they cannot turn further without collapsing the arms.
