Parkour was developed in France in the late 1980s by Raymond Belle and further popularized by his son David Belle and their group, the Yamakasi. It involves training oneself to navigate through the urban environment and overcome obstacles using efficient movement. To practice, one should train naturally with conviction and intelligence while focusing on fun. Key equipment includes sneakers for cushioning falls and jumps as well as breathable, lightweight clothing. Safety gear like gloves may also be used depending on the environment. Ultimately, parkour is a discipline that provides a sense of freedom when one feels in control through practice.
