An excellent book. Inspiring, informative, educational. Great for revision and motivation. The sort of book that you can pick any page and learn something new. Although based around Karate, as an intermediate Tae Kwon Do enthusiast I find it invaluable. A must buy for anyone serious in martial arts, I believe it is suitable for all abilities. The author's style is infectious and inspirational. It covers all aspects of the art from improving hand techniques, improving kicks, to solo training, sparring, etc. You do not have to read this book from start to finish, it's layout means that the information you require is at hand very easily. I believe that aided with this book and the inspiration and motivation it's given me, with a little effort in my own time I will have unfair advantage over my fellow students.
