The Characteristics of Hunter-Gatherer Fitness | Mark's Daily Apple

Dr. Loren Cordain and a few MD colleagues have recently published a paper (PDF) called “Organic Fitness: Physical Activity Consistent with Our Hunter-Gatherer Heritage.”
Thoughts?

I am currently gym-less, but I ride my bike daily for transportation, walk the dog, and am about to go back to my aiki jujitsu training. I would like to get a fitness system going that is "organic" and not forced, and have been reading up on the Primal Fitness site.. I like his philosophy -- it makes a lot of sense to work with the body instead of against it.
"The challenge is to be yourself in a world that is trying to make you like everybody else."
"...rationality is not necessary to sell things.."
My staples: Mane n Tail (cowash), Garnier Fructis Sleek n Shine (leave in condish), Grapeseed oil or shea butter (sealing), Organic Root Stimulator Elasticitea (leave-in condish & light hold)
