Just look at this video. It is indeed breath taking. The first jumps were shocking enough. But the second round is even still more shocking. The height is way over their heads. I wonder how they can do that. Maybe all you need is a little bit of practice and knowledge on how to perform it. Being just high school students, they cannot be highly experienced in this event. Anyhow they seem to be professional jumpers judging on the way they land on the other side without falling or toppling. Surely this is something which anyone can’t do. You definitely need to have it in yourself.
