Abstract
Abstract A method of teaching golf utilizing a progression of golf balls of diminishing size. In one aspect, the method provides for starting with an oversize ball and using several increasingly smaller balls as the playing ability of the student improves until a conventional size ball is used. The method also contemplates the use of golf clubs with oversize heads. The present method contemplates a one-step reduction in the size of the golf club head from oversize to conventional size.
