Parkour is "the Art of Movement" and made somewhat popular in movies like District B13 and Casino Royale, a James Bond movie from a few years ago.
The Michigan Parkour Club which practices in a concrete courtyard at the School of Dentistry at the University of Michigan takes on obstacles head on that you & I would just as easily want to walk around.

It's a great workout as well and best of all it's free you just have to find the right place to do it.
