Parkour is a sporting discipline that challenges the body's ability to move along a particular course in a creative, effective and varied way. The aim is to rapidly clear obstacles using a variety of techniques: jumping, balancing and climbing. Parkour can be practised either outdoors (making use of features of the urban or natural environment) or indoors (using vault boxes, benches or other obstacles). It also serves an educational purpose in that it enables children and adolescents to realistically gauge their own abilities and to select their own focus – whether camaraderie, mutual help, or simply enjoyment.
