This book is truly a classic! It had and continues to have a huge influence on my coaching. Even though the Fourth edition was published in 1985, many of the concepts and principles are as relevant today as they were then. Even though this is a track & field oriented book it is a must read for all coaches who are interested in coaching the person in a systematic and holistic manner. It just underscores how Ken Doherty was an innovative thinker who was way ahead of his time.
If you are interested in looking deeper into his work I recommend his classic textbook Modern Track and Field which was a textbook for my Theory of Track & Field class in 1968. I also recommend Modern Training for Running if you work with middle distance or distance athletes in any sport.
