Each golfer has a way of swinging the club that is most effective for him or her. The author helps you put together a swing based on what your body can do naturally.
Typical instruction follows a "one system fits all" approach of some type. Any given one might work for a very small percentage of players but not the majority. We've seen the negative results of such thinking at every level of the game. Professionals make swing changes and fall off the tour or perform poorly. At the amateur level, a very high percentage of golfers never reach full potential.
E.A. Tischler's series of books, especially this one, is different and takes instruction to another level. His work focuses on finding what you can do given biomechanics and body structure, not what works for the elite golfer or a certain pro. What is presented will work best for the intermediate or experienced player trying to improve his or her full swing. My guess is it will be over the heads of beginners who should probably see a pro to learn the basics of grip, alignment, etc., then give this book a look down the road.
Photographs help make some of the key points. The writing is clear and key points are repeated. It is well worth a look.
