The main aim of Parkour is to use your body to move from one point to another as efficiently and quickly as possible. Parkour focuses on fast, effective movement in the form of running, jumping and climbing to overcome any obstacles that may come in the way. The sport is practiced both in rural and urban environments and the obstacles may range from branches and terrains to rails and concrete walls. To see an expert Parkour practitioner(traceur) perform is to see poetry in motion.
