This is a very simple book covering a very broad topic. I said simple, but that doesn't mean it's not good. He mentions treating the whole athlete instead of spot treating individual symptoms/injuries. What a novel idea. I look forward to implementing some of the techniques mentioned here. Maybe I can improve my performance.
He has some sound principles, based on science, in this book, but I think he is off the mark in many areas. I don't think you will find many exercise physiologists that agree with many of his training methods. His writing style isn't great, but there are nuggets of truth in the book that can be useful in training. I just wouldn't want to base my training on only reading this book.
Maffetone is also Anthony Robbin’s trainer. The concept of lactate threshold, aerobic, anaerobic training. Intelligent training. Minimum effort with maximum benefit.
In general, the training suggestions in this book are good. Specifically, I like the focus on maintaining overall health including adequate rest and stress management. However, the book is at times simplistic. The author implies that if you follow his training suggestions you won't ever get injured. His suggestions may very well help, but injuries are often unavoidable.
I don't plan on following the precise training program outlined in the book, but I do plan on incorporating several of its components into my routine.
