Parkour is a training discipline using movement that developed from military obstacle course training. Practitioners aim to get from one point to another in a complex environment, without assistive equipment and in the fastest and most efficient way possible. Parkour includes running, climbing, swinging, vaulting, jumping, rolling, quadrupedal movement, and other movements as deemed most suitable for the situation. Parkours development from military training gives it some aspects of a non-combative martial art.
Parkour is an activity that can be practiced alone or with others, and is usually—but not exclusively—carried out in urban spaces. Parkour involves seeing ones environment in a new way, and imagining the potentialities for navigating it by movement around, across, through, over and under its features.
Parkour was developed in France, primarily by Raymond Belle, and further by his son David Belle and his group of friends, the self-styled Yamakasi, during the late 1980s. The discipline was popularized in the late 1990s and 2000s through films, documentaries, and advertisements featuring the Yamakasi. (source : wikipedia)
