Parkour (sometimes abbreviated to PK) is a utilitarian discipline based upon the successful, swift and energy-efficient traversing of one's surrounding environment via the practical application of techniques, based around the concept of self-preservation and the ability to help others.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. The usage and employment of flips into the named route does not constitute parkour.
