Parkour is the art of moving through your environment using only your body and the surroundings to propel yourself. ~ The goal is to overcome obstacles quickly and efficiently, without using extraneous movement. ~ If the intention is to get somewhere using the most effective movements with the least loss of momentum, then it could probably be considered Parkour.
Parkour is not acrobatics, tricking, stunts, recklessness, or jumping off high objects for no reason.
Free Running has grown to be descriptive of a sort of “cousin” activity to Parkour – Free Running is more expressive and creative in nature, with moves such as acrobatics, flips, and spins added for flair, creativity, or just because someone wants to.
Parkour was created in Lisses, a medium prosperous suburb of Paris, in the early nineteen-nineties, by a reserved and restless teen-age boy named David Belle. His father, Raymond, who died in 1999, was an acrobat and a hero fireman.
Free running is pretty impressive . I think Adidas , or Nike had an advertisement where they were promoting their products showing a free runner doing an expressive and creative number.
I really like to watch free running. My favorite part is when they run up the side of a building, and pop onto the roof with (what looks like) little effort.
