I've read the book many times. I really enjoyed his bio. I appreaciated the honesty in it. One of my favorite parts in the book is when he comments on the difference between his body in rocky 1 and in rocky III, it took him 6 years of hard working out to get that body. Then he comments on how he did it and how ignorant he was when he was younger, working harder instead of working smarter.
But the thing that sticks out the most for me in the book, was his secret to training. A great way to energize yourself; something I emulate. The secret is JAVA, a nice cup of cofee but in my case u suppliment it with a nice Cold carmel Frapachino from star bucks. hehe
Keeps me awake and energized when I do my workouts.
If I were you, I would adivise that you take a look at the workouts he does, he gives plenty of examples, although the book is not exactly the most thorough with explanations on exercises, there are better books for that. For me it was the bio that was inspirational. If yor just interested in exercises best to buy a book that directly touches upon that subject.
