Walk it out
Another sign of transformation. See this editorial in the July 2007 issue of Mayo Clinic Proceedings.
The medical community is starting to come around to the idea that exercise doesn't have to be lumped into a single high-intensity bout. Rather, it can be distributed over the course of the day; a lifestyle which parallels our history as hunter-gatherers. Our paleo ancestors certainly had their moments of intense physicality, but the defining quality of their lives was their consistent locomotion throughout the day. In other words, lots of walking!
