I normally do not review many things but I have to make an exception in this case. Been golfing for some 50 years and am the owner of many golf self help books. Some have helped me in the past but golf is a very technical sport. This book is one of the smallest instruction manuals of its kind but I find that for me at least it is the most helpful one. I am not sure that it is for the new golfer as it does not contain instructions on the grip setup or other basics but it is not meant to be. There are many other books that do that. This book just focuses on two elements of the swing, the back swing and generating lag in the swing. It succeeds on both counts. With his back swing instruction I have eliminated many swing thoughts that worked against me while playing. If you follow his instruction it will take you into the desired slot for your club. I for years have had a very shallow swing plane that has hindered my swing. Although at times I have made it work ( 8 handicap) it is far from consistent. This book changes all that. It has put me into the desired slot to begin my downswing. I think that if you focus on his back swing instruction first it will help improve you ball striking and then you can proceed to his instruction of generating lag. Overall the best golf instruction book I have purchased.
