Movements :

There are fewer predefined movements in parkour than in gymnastics, as there is no list of "moves". Each obstacle a traceur faces presents a unique challenge. The ability to overcome the challenge depends on multiple factors, for example, on body type, speed, angle of approach, the physical make-up of the obstacle. Parkour is about training the "bodymind" to react to those obstacles appropriately with a technique that is effective. Often that technique cannot and need not be classified and given a name. In many cases effective parkour techniques depend on fast redistribution of body weight and the use of momentum to perform seemingly difficult or impossible body maneuvers at great speed. Absorption and redistribution of energy is also an important factor, such as body rolls when landing which reduce impact forces on the legs and spine, allowing a traceur to jump from greater heights than those often considered sensible in other forms of acrobatics and gymnastics.^{[citation needed]}
According to David Belle, you want to move in such a way that will help you gain the most ground as if escaping or chasing something. Also, if you go from A to B, you need to be able to get back from B to A,^[23] but not necessarily with the same movements or passements.
Despite this, there are many basic versatile and effective techniques that are emphasized for beginners. Most important are good jumping and landing techniques. The roll, used to limit impact after a drop and to carry one's momentum onward, is often stressed as the most important technique to learn. Parkour has sometimes received concerns for its health issues due to large drops.^[24][25][26] Communities in Great Britain have been warned by law enforcement or fire and rescue of the risk in jumping off high buildings.^{[27][dead link][28]} Although David Belle has never been seriously injured while practicing parkour,^[29] there is no careful study about the health issues of large drops and traceurs stress gradual progression to avoid any problems. American traceur Mark Toorock says that injuries are rare "because participants rely not on what they can't control – wheels or the icy surfaces of snowboarding and skiing – but their own hands and feet," but Lanier Johnson, executive director of the American Sports Medicine Institute, says "It's really hard to get people to report these kinds of injuries."^[30]
