I have a lot of books on drawing and this is easily the best book I have found for drawing male bodies and muscles. I really like that it gives you examples of actual men next to the drawings so you can see how the muscles translate from life to the page. They are very good at breaking down each muscle and muscle group and showing you how to draw them in different degrees of development. You are also given examples of the male form in many different poses. In the back of the book there are hundreds pictures of the male models in different positions. (I assume these are also on the CD Rom that comes with the book but I have not tried it yet. )
