Yeah, it is an amazing read. A good read for any starting boxer. Also pummels you with the importance of technique with a lot of information. Keeping in mind some of Dempsey's tips while working the heavy-bag and etc for a long time, you'll be punching like a pro.
It's also kind of funny and inspiring to read. Like the part where he points out Williard looked like the victim of a premature mine blast by the end of round 1. haha.
