Parkour!
Parkour – Wikipedia, the free encyclopedia
Parkour (IPA: /pa?.’ku?/, often abbreviated PK) is a physical discipline of French origin in which participants attempt to pass obstacles in the fastest and most direct manner possible, using skills such as jumping, vaulting and climbing, or the more specific parkour moves. The obstacles can be anything in one’s environment, so parkour is often practiced in urban areas because of many suitable public structures, such as buildings, rails, and walls.
