This article is pretty cool. http://lifehacker.com/5390921/run-like-a-hunter-for-injury+free-workouts
I've always thought it would be cool to run like a deer through the woods up and down hills. Something about zigzagging through the trees and creating your own breeze makes me smile inside.
I like the case for running barefoot. Turns out that shoes make us run differently and that can cause more injuries. When I grow up and have a house (which will include some land, I hope) I want to run around barefoot. Being in school and in an apartment has restricted my barefootedness.
In the New York Times article that is the main source quotes Dr. Lieberman, “Your butt is a running muscle; you barely use it when you walk.” There you go.
