I've read this book twice now as I really wanted to follow the workout and nutrition program to the letter. After two weeks on the fall program I have really noticed a difference in my body. I was in pretty good shape before but now my body looks more defined and bigger (well my abs aren't bigger thank God). Which makes sense as the exercises Nate recommends cater specifically to working your biggest body parts (chest, shoulders, upper back, and legs) intensely with predominantly multi-joint exercises. You won't be doing chest fly's, lateral raises, leg curls, leg extensions, or calf raises. And here's where he'll lose a few people (and he nearly lost me when I read it) but you'll pretty much only be doing biceps curls and triceps extensions for six weeks out of the year long program. I nearly sent the book back when I read that.
However whatever concerns that I had initially have vanished, as my arms looks as muscular as before but bigger which hasn't happened for a while. The workout programs that Nate provides almost ensures that your body won't adapt. You'll be going back and forth from an upper / lower body split to whole body training. And if that weren't enough his set and rep variables (undulated periodization, super sets, giant sets, back-off sets, and everything in between) will shock your muscles to new growth during every phase of the program.
If there was one aspect of the book that I wish Nate would have provided more insight on was nutrition. He pretty much breaks down what foods to avoid and what types of foods to eat but had this book had a meal plan and recipes to follow I would have rated it five stars. Nate doesn't come across as the type of guy who gets all bent out of shape about the small stuff so I assume most of the meals he eats would be more practical and useful than what you usually see with these kind of books.
Unlike other fitness books though Nate's advice goes outside the gym and kitchen to such diverse topics as clothing, style, and presentation which surprisingly he succeeds at. As stated by other reviewers his tips and recommendations in these regards are spot on and not as crude or overly macho as you would expect with the title of the book. What really stands out in this book though is Nate's sense of humor which really made the book better than your average fitness text and made it more personable and easier to relate to.
All in all this is a good book that I would highly recommend. It doesn't cover quite all the topics in as specific detail as I would of liked (nutition mostly) but his reading recommendations have pointed me in the right directions to have whatever remaining questions I have answered.
