I am a Physical Education teacher and purchased this book for the training and evaluation sections. I thought the training guide was particularly useful in summarizing the basic principles of fitness training. The evaluation section is exceptional and it is the first time I have seen such a thorough explanation in one book. I would highly recommend this book to anyone involved in fitness training or education even though it was directed to police and firefighters. It is well written and researched and I find it a very valuable tool in my field.
