Freedom Running

Parkour (sometimes also abbreviated to PK), also parcours, or l'art du déplacement (the art of moving) is the physical discipline of training to overcome any obstacle within one's path by adapting one's movements to the environment. It is a non-competitive, physical discipline of French origin in which participants run along a route, attempting to negotiate obstacles in the most efficient way possible. Skills such as jumping and climbing, or the more specific parkour moves are employed.

The term free running was coined during the filming of Jump London, as a way to present parkour to the English-speaking world. However, free running and parkour are separate, distinct concepts — a distinction which is often missed due to the aesthetic similarities. Parkour as a discipline emphasizes efficiency, whilst free running embodies complete freedom of movement — and includes many acrobatic maneuvers.

Gravity or Police, these guys don't believe in any law. Idolised by the youth of Paris as much as they're hated by the police, they are the Yamakasis, modern samurais. With acrobatic skillfulness and adrenaline pumping belief in their own immortality, they throw themselves out from incredible heights, and jump from roof to roof.

Best parkour video ever? Probably not.
