"Parkour (sometimes abbreviated to PK) is a utilitarian discipline based upon the direct, successful, swift traversing of one's surrounding environment via the practical application of techniques, based around the concept of self-preservation. It is a non-competitive, physical discipline of French origin in which participants run along a route, attempting to negotiate obstacles in the most efficient way possible, using only their bodies. Skills such as jumping, climbing, vaulting, rolling, swinging and wall scaling are employed. Parkour can be practiced anywhere, but areas dense with obstacles are preferable and it is most commonly practiced in urban areas."
Thank you wikipedia for being an all knowing font of information. The video also has freerunning elements, which is a flashier, more competitive version of parkour.
Now, I'd like to ask my follower's views on parkour, so the subject is open to debate.
Also, up to 66 followers! Feels awesome.
