One way to minimize injury in case of a paragliding crash or a hard landing, is the Parachute Landing Fall (PLF). The whole idea of PLF is to be a spring to absorb the energy of the impact. So if you are on a paraglider that is landing hard and you go defensive, by putting your wrist out or your leg out, you will break it. But a good PLF technique will minimize the risk of a bad injury. It is very important to learn and keep practicing, so it becomes instinctive, should you ever need it.
