Review:

This book is truly a classic on the biology and anthropology of exercise. I first stumbled upon it in the bookstore when I was just looking for some more books on running. I wasn't looking for anything in particular and I picked up "Why We Run" off the shelf to give it a chance.

It was just what I was looking for.

The exploration of human anthropology and the scientific explanations of why we run were in exact alignment with my beliefs. Heinrich's basic assertion is that we run because we're supposed to run. Our systems are made to use fatty acids and glycerol as fuels for long distance, nomadic type activities, not quick glucose intensive activity.

This clearly sheds light on the heart rate formula for weight loss and what is particularly best for any specific person. If Heinrich's points are correct, then the conclusion would be a lower heart rate is most effective for weight loss and the preferred zone for any type of exercise. Any exercise in the higher heart rate zones could be classified as survival training--or expending energy that is meant for fight or flight type activities, like running away from tigers or the like. This is clearly not anything we have to do in our modern times.

Heinrich goes to great lengths to explore his arguments. He takes the biology of the other animals and compares them to ours in a very "easy-to-read," unscientific way--something that is relieving for anyone who's spent hours with their nose buried in anatomy books.

The book is anecdotal, because Heinrich bookends the story with his own 100K run. This makes the book entertaining as well and not just a dry scientific read. It's also great biological justification (translated: "excuse") to tell a spouse who thinks you spend too much time training for the next big race!

Perfect for runners and walkers who want to understand their body and what is best for optimal health!
