Have you heard of this? I just did, and I can’t even start to explain how crazy it is! I’d advise you to check out the video I found on YouTube (below).
For a definition, I turned to Wikipedia. Here’s what they had to say about this “art form.”
Parkour (sometimes also abbreviated to PK) or l’art du déplacement (English: the art of movement) is an activity with the aim of moving from one point to another as efficiently and quickly as possible, using principally the abilities of the human body. It is meant to help one overcome obstacles, which can be anything in the surrounding environment—from branches and rocks to rails and concrete walls—and can be practiced in both rural and urban areas. Parkour practitioners are referred to as traceurs, or traceuses for females.
Founded by David Belle and a group of friends in France, parkour focuses on practicing efficient movements to develop one’s body and mind to be able to overcome obstacles in an emergency.
So, is this something new for you? I’m definitely going to keep checking this out from time to time. It looks like stuff you only see in movies!

Do you know Charles Fisher? He introduced a lot of the students at LCC-EC to this back in 2002 and got pretty good at it. The movie Casino Royal was probably the biggest introducer of the phenomenon to the mainstream when it dedicated the entire opening sequence to this. One of its originators is the one actually playing the role of the bomb maker and doing his own stunts for the sequence. It has been labelled one of the most dramatic and awe-inspiring openings in Bond history. Only the crane jumps were digitized, everything else was actually done… Art imitating life!
