Book in very good condition. Pages are clean, tight and unmarked, apart from slight foxing. The cover is also in very good condition, with very slight creasing on one corner. In an effort to clarify the misconceptions on the seemingly simple swing plane, this book reveals the truth and fundamentals hidden behind. The book introduces the Striking Plane Swing Model, which has been extracted from the swings of numerous great ball strikers in history. The model defines the essence of the swing and the proper sequence of club movement, and is based on the laws of classical mechanics and the knowledge of human anatomy. This book will show you why and how many of existing swing plane theories are flawed. A simple but accurate swing analysis method is also introduced and can be used to analyse your swings and pinpoint your issues. Golfers of all levels can benefit from the concepts discussed in this book and will be able to look at the golf swing from a brand new perspective.
