Good for beginners but...
This book contains a lot of anatomy which is great if you need that aspect but if you are looking for the dance technique part, this book is lacking.
Types of injuries and treatments for injuries are discussed, there is a small prevention section which is mostly basic concepts such as good technique, proper nutrition and muscle strength and joint mobility. When technical faults are discussed they are mainly the usual suspects such as spine problems like scoliosis, turnout tightness, hyperextension of knees and problems with feet.
Although I would recommend this book as a basic starting point for those who have had no intro to dancers anatomy and common problems but for those that need more into the problems of technique, I would look elsewhere
