发明名称 GOLF SWING TRAINING DEVICE AND TRAINING METHOD
摘要 <p>A slidable grip (20, 100, 200) for one hand is provided on the shaft (12, 312) of a modified golf club (10, 200, 300) to enable a golf trainee to separate his or her hands progressively during a backswing and being them back together progressively during the downswing. This technique imprints proper swing mechanics in the mind of the trainee to be recalled reflexively in executing a conventional golf swing with the hands in a fixed grip relationship on the handle (14, 114) of a golf club.</p>
