Golf My Way: The Instructional Classic, Revised and Updated

Written in the early '70s, Golf My Way is the first of the truly modern instructionals mixing physics and kinesiology with theory and technique. The writing's a little dense, but the illustrations are quite good, and some of the mental exercises nothing less than revolutionary. If there's a caveat to Golf My Way, it's that Jack's way works for Jack's game, and may not mesh with yours. Then again, this is the book that introduced Ernie Els to golf, and look what he's done.
