Parkour (sometimes abbreviated PK) is a method of movement focused on moving around obstacles with speed and efficiency. Originally developed in France, the main purpose of the discipline is to teach participants how to move through their environment by vaulting, rolling, running, climbing and jumping. Traceurs (parkour practitioners) train to be able to identify and utilize alternate or the more efficient paths. Parkour can be practiced anywhere, but areas dense with obstacles offer many different training opportunities.
