I haven't tried it, so I can't comment on if it works or not. I did buy the book, and the only part of the program I really didn't understand was the reps day. He goes from 8 reps, to 6 reps down to 2 reps. When I hear reps, I'm thinking 10+. Other then that, the program doesn't look that bad. It's a good book with some good information. Also, from watching his videos, his training looks a little different from what his book is saying.
