This book is for every player who feels stuck and frustrated by lack of improvement. It is the perfect guide to understanding and developing every aspect of the game. After writing Developing High Performance Tennis Players - a system to develop competitive players - I wanted to utilize my fifty years experience as a competitor, high performance coach, coaches coach and instructor of players of all ages and levels to write a practical book with the most effective strategies for anyone to improve and enjoy the game. The book breaks tennis down into ten performance-determining factors that directly establish a players performance level: consistency, precision, footwork, perception and anticipation, variation, spin, ball speed, camouflage, mental skill and decision making. Each chapter addresses one of these factors and presents simple and effective tips and exercises to develop it, ultimately improving overall performance. This guide is the perfect long-term companion for any player. It can be read cover to cover or selectively by focusing on the chapter that addresses immediate, specific problems or concerns.
