The Efficient Golfer is the first golf book to show readers how to videotape, measure and analyze their swing and putting mechanics. It is intended for single-digit or better players who want to increase the precision of their ballstriking. All that is needed to analyze your swing is this book, a camcorder with a high-speed shutter and frame-by-frame playback, a tripod, a large screen TV, a protractor, and an erasable marker. Once you have read through the book, the initial analysis of your swing and putting mechanics will take about an hour. You will be able to measure your Range (how far you turn away from the ball), Sequence, Speed, Separation and Alignment. By measuring your mechanics, you will be able to uncover problems in your swing that are not visible by just watching a videotape. Once you have uncover any swing problems, the book makes recommendations for fixes and improvements. The book also has chapters on the yips and low back pain, as well as directions for measuring your flexibility for golf. Professional golfers who have used this system have won the US Open, improved their tour ranking in putting average from #113 to #1, increased their longest drive from 295 to 400, and quadrupled their tour income. The book is intended only for personal use and not for commercial or education applications.
