Parkour (French pronunciation: [paʁkuʁ]) is a 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. This is done using only the human body and the surroundings for propulsion, with a focus on maintaining as much momentum as possible while still remaining safe. Parkour can include obstacle courses, running, climbing, swinging, mantling, vaulting, jumping, rolling, quadrupedal movement, and other, similar movements depending on what movement is deemed most suitable for the given situation. Parkour’s development from military training gives it some aspects of a non-combative martial art.
