What are the most popular extreme sports
bungee jumping: This is a very popular extreme sport now. The experimenter ties the safety rope to his body, and then jumps down from the high platform to experience the feeling of free fall.
skydiving: skydiving, like bungee jumping, is a free fall experience, It's just that skydiving is more exciting. Skydiving must be accompanied by professionals, and must be trained before skydiving.
mountaineering: many people like mountaineering. The mountaineering here is not the kind of mountaineering we usually travel, It's climbing cliffs with bare hands. This sport requires high physical fitness and needs us to exercise well.
submarine diving: this sport is also deeply loved by everyone. Many people want to see the scenery under the sea. This sport requires us to train in advance, otherwise we can't bear the great pressure brought by the deep sea.
