Query: For Girls Only

This book should be entitled "Fitness for Teenage Girls." Both the information that it contains and its tone are directed exclusively at young women. This is not a bad thing, but be advised that there is nothing for young men here. To be fair, this fact should be obvious from a glance at the book's cover photo.Moreover, while the book contains reasonable advice regarding nutrition, exercise, and body-image, there is nothing to justify the 20+ dollar price. Borrow it from a library.
