I like this book for youngsters, maybe K-1st grade. It's not too complicated, but it gives a description of chakras. The thing I don't like about this book is that it's broken into two basic parts: yoga and aerobics. It should have just kept the focus on stretches and yoga. The aerobic section is brief and gives little detail. I like that the each aerobic activity is accompanied by stretches that are best suited for the sport. But honestly, if the book had just ended on page 29, I would have given it another star.
