Parkour (French pronunciation: [paʁˈkuʁ]) (abbreviated PK) is a physical discipline of movement focused on overcoming obstacles. Developed in France by David Belle, it is a method of training the human body to become stronger, more agile, and faster, while remaining efficient and able to move more freely. Participants learn to pass diverse obstacles by combining a variety of movements like running, climbing, swinging, vaulting, leaping, and rolling. It uses no equipment and is non-competitive.
