Abstract: A golf swing training device includes an indicator rod mounted adjacent the golfer's shoulders by a shoulder mount and extends a predetermined distance from the golfer substantially perpendicular to an axis defined by the golfer's spine. The indicator rod is adapted to be guided by a guide member or structure supported adjacent the golfer so that as the golfer performs a golf swing the indicator rod engages and follows, but is not constrained by, the guide member or structure throughout the swing. The guide member or structure is effective to urge the indicator rod and thus the body movement of the golf in a preferred motion and to provide information regarding deviations from the desired swing. The information is provided by visual observation of the indicator rod and sound as the indicator rod movingly engages the guide member or structure.
