Increase your physical performance and stamina, reduce your resting heart rate, train more effectively with less pain and drudgery, live longer and healthier, and perform better in sports with expert advice from sports physician Philip Maffetone. Foreword by Mark Allen. Revised and updated ed.
There are definitely better and more up to date books on this subject. The section on heart rate monitors is mostly useless to the modern reader looking to purchase a heart rate monitor. The nutrition section does not match the current nutrition advice given on Dr. Maffertone's website. Also, despite the cover, title and blurb suggesting this as a multi-sport book, it really focuses on cycling with only half a chapter each devoted to running and swimming which were not very helpful in aiding a runner or swimmer to translating the cycling suggestions to something applicable to their sport.
For an more updated book on this topic, I highly recommend Primal Endurance by Mark Sisson and Brad Kearns. If you really want a book by this author, I would suggest looking into some of his more recent publications (haven't ready any personally) or just checking out his website.
Read the book and followed the advice before my first brain surgery. Since then I have had 30 more brain surgeries and four spinal cord surgeries(plus a few minor surgeries). I was given a ten percent chance of surviving after the first surgery and I am still here eight years later.
