This is a very readable book, explaining the need and "how to" of exercise and detailing a safe way to accomplish it. The exercises are explained in detail with pictures, but I find it hard to try to do them while having to look at the book frequently to make sure I am doing them correctly. I do better at watching the DVD I ordered, to learn the moves, and then duplicating them. Teresa Tapp is a very motivating personality and I would recommend people try out her plan, and reading the book first, is a great place to start before buying the DVDs. It gives a good overview of the process and the "whys" and the basic "hows." I found it very interesting.
