I loved this book! As a new swimmer, it was very helpful, especially the section where the author describes terms used in swimming. My swimming partner, a seasoned swimmer, loved the book so much that she immediately ordered a copy. We shared the book between two lanes and were able to flip back from the basic workout (for me) to a more advanced workout for her. During our first workout I accidentally dropped the book in the water. I dried it off and it is as good as new.
