You've found it!
I remember a few months ago coming across a blog/site which had some good paleo style workouts.
One that comes to mind is 3 people (2 guys, 1 girl) doing some sprints, push ups etc in Philadelphia ending with them running up the stairs like Rocky. Something tells me 2 of them were siblings?
If you guys recollect this, please post the link or site.. I'm trying to find more sprint workouts and I liked that site when I came across it.
wow that was fast... cheers.
