Abstract: A training apparatus for temporarily increasing the weight of a golf club head has a body member having a perimeter profile which may at least partially mimic that of the golf club head and has a substantially flat surface for positioning adjacent the striking face of the golf club head. When fixed to the head of a golf club, the training apparatus increases the weight of the club and redistributes the center of gravity closer to the club head, allowing the golfer to benefit more from warm-up swings prior to actual play. The training apparatus may be formed of metal and contains a cutout or cavity in which a magnetic material resides to enable temporary attachment to the club head. In various other embodiments, the body member of the training apparatus may be substantially formed from either all metal or all magnetic material.
