Parkour, also known as PK, is a real-life martial art in the Street Fighter games.
Parkour is a training discipline of French origin and it uses movement 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. Parkour's 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 one's environment in a new way, and imagining the potentialities for navigating it by movement around, across, through, over and under its features.
