Look what you started maldoure. Anyway, when you see someone flip, any kind of flip, they are tricking. Call me a hater, but parkour is not about showing off in any way, shape or form. If the flip was the fastest way down a ledge or up a ledge or across a field, then it is parkour, but when people do parkour these days they add in their own mixture of tricking. Have you ever seen a jump to anywhere that could have been faster with a flip in it?
What is David Belle then?
A traceur? A tricker? A gymnast? A martial artist?
Because acrobatics, and movements such as palmspin, have been used since the early 90s by all of the founders. Training with lack of food and water is not efficient, sleeping on the floor is not efficient, doing handstands is not efficient, practising self-defense is not efficient, interacting with the environment is often not efficient, doing conditioning drills is not efficient, stretching is not efficient, playing is not efficient, eating is not efficient, sleeping is not efficient..in terms of
moving from A to B in the fastest way possible.
Its true that parkour or freerunning is not about showing off, and acrobatics is a completely separate dicipline, but claiming that just because someone is doing a backflip, then it isn't parkour, is like saying that doing a kong isn't parkour. And it is true. Because parkour isn't simply the act of doing a kong or a backflip. That is why I think its important not to label to much and put it in different boxes. I think its important to look at it as a whole. It is a training method and a specific way of thinking.
