Parkour

Parkour (French pronunciation: ​[paʁˈkuʁ]) is a holistic training discipline using movement that developed from military obstacle course training. Practitioners aim to get from A to B in the most efficient way possible.They do this using only their bodies and their surroundings to propel themselves; furthermore, they try to maintain as much momentum as is possible in a safe manner. Parkour can include obstacle courses, running, climbing, swinging, vaulting, jumping, rolling, quadrupedal movement, and the like, depending on what movement is deemed most suitable for the given situation.
Parkour is a non-competitive activity, which can be practiced alone or with others. It can be practiced in any location, but is usually practiced in urban spaces. Parkour involves seeing one's environment in a new way, and imagining the potentialities for movement around it.
Developed in France, primarily by Raymond Belle, David Belle, and Sébastien Foucan during the late 1980s, Parkour became popular in the late 1990s and 2000s through films, documentaries, and advertisements featuring these practitioners and others.
Parkour's training methods have inspired a range of other activities, including freerunning and l'art du déplacement. Although their creators define them as separate activities, practitioners and non-practitioners alike often find it difficult to discern the differences between them.
