Query: A wonderful book! Changed my life...

I would like to thank Gary Null for getting this book out to the public. It's helped me get back my health. I'm 54 and could hardly walk a 100 feet before starting these exercises. I'm walking 3 miles daily now and have lost 70 pounds and I owe it to Gary's advice from this book. The book breaks down each exercise routine into east to follow steps and gives plenty of great info about diet. I would also like to point out a rather suspicious review from Publishers Weekly. This review slams this book and I really don't know why. The complaint seems to be too much information for advanced runners. Well if you're an advanced runner any book for beginners to advanced will have info in it that's covering what you already know. I believe this is just another establishment crony looking to take a shot at a leader in the alternative medicine and holistic health field. Thanks again Gary
