Been posted before. That's free running or Le Parkour. It was created by a guy named David Belle from France. You've probably seen this stuff in some shoe commercials. Pretty amazing what those guys can do. I wonder if anybody who does it has died?
Thanks for the insight. I didn't know there was a name for it. As for being posted before I guess I need to start reading all of them, regardless of how long it takes. How long ago was it on here?
I did a search, it was September. I don't think you would have found it without knowing the official name though. Anyways, here's a site by one of the co-founders, Sebastian Foucan. There's history and the philosophy behind it. Also, some short clips and basic instructions. http://www.parkour.com/
