Parkour (sometimes abbreviated PK) is a physical art of French origin, the aim of which is to move from point A to point B as efficiently and quickly as possible, using principally the abilities of the human body. It is meant to help one overcome obstacles, which can be anything in the surrounding environment — from branches and rocks to rails and concrete walls — so parkour can be practiced in both rural and urban areas.
