Parkour (abbreviated PK) is a training method which focuses on rational movement in both the natural and urban environments. The focus is to move around obstacles with speed and efficiency. 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. Parkour practitioners are known as traceurs. They train to be able to identify and utilize alternate, more efficient paths. Parkour can be practiced anywhere, but areas dense with obstacles offer many training opportunities.
