When training Parkour we learn a lot of different movements, jumping, rolling, running, swinging, pushing, pulling and so on. Sometimes we also learn how to fall without getting injured.
This is a skill, really. A skill that consists of awareness, reaction ability and the understanding that you need to keep the momentum, distributing the force through out the body. This is somewhat amazing to look at. And people, who train bail-techniques often, can become extraordinary at falling.~ Marcus Grandjean from, http://www.streetmovement.dk/thoughts-from-our-crew/2014/9/17/parkour-bones
