Parkour

I just discover Parkour by accident. Had always been curious about this, but never knew the proper keyword to search on.

Extract from Wikipedia:
Parkour is a physical activity that is difficult to categorize. Often miscategorized as a sport and extreme sport, parkour

(sometimes abbreviated to PK) (English: the art of displacement) 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 in France, parkour focuses on practicing efficient movements to develop one's body and mind to be able to overcome obstacles in an emergency.
