"Our aim is to take our art to the world and make people understand what it is to move," said David
Belle, the founder of parkour(跑酷).
Do you love running? It is a good exercise, yet many people find it boring. But what if making your
morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several
blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has
become popular worldwide.
Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as
possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour is
considered an extreme sport. As its participants dash around a city, they may jump over fences, run up
walls and even move from rooftop to rooftop.
Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more
than that.
Overcoming all the obstacles on the course and in life is part of the philosophy(理念) behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if
in parkour and never fall back from them in your life, to reach the destination successfully. A parkour
lover said, "I love parkour because its philosophy has become my life, my way to do everything."
Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at any time,
anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence.
