Golf training club and training systems

Abstract

A golf club for improving training for young children includes a grip, a shaft and a clubhead. The clubhead is oversized with a volume from about 1100 cm 3 to about 1400 cm 3 . A swing weight, a ratio of a distance between a club balance point and a butt portion of a grip to a total club length, and/or a ratio of a total club mass to a distance between a club balance point and a butt portion of the grip are determined for improving use by young children. A golf training system includes a golf club and a corresponding training glove.
