Not a particularily brillant book. Sports psychology is a very complex topic and individual to each sport. This book attempts to bracket them all together.
This book is probably of most use to those undertaking activites where technique is the most important factor (e.g. golf, football kick, gymnastics) but of less use in endurance sports (where controlling the pain and pushing to the limit are important).
Contains lots of exercises to do with checklists and tables to support them. Useful if you are attempting to follow the programmes given in the book.
