Query: Pretty Good Book

I had to order this book for a circus performance class, and although I had to drop the class because I was taking too many credits, I decided to keep the book because it had so much good information in it. As a gymnast I found the sections on equilibristics to be very interesting, and pertinent to my sport. Overall this is a very good book on body mechanics and the application of physics.
