With most of these very specialized books, kowing the reviewer's background (me) is critical in understading the review. I am a tennis coach both private and high school and I have been doing it for about 5 years.
This book is phenomenal for just about everything I want to do on the court. I had picked up via other books or word of mouth or other coaches, most of what was in this book but nowhere was it all packaged in a single handy reference. I had checked this out of the library but once read, I promptly bought it for my kindle. From nutrition to non-static warm up excercises to on court drills this book covers it. A must have for any coach hoping to make their planning easier/simpler.
