Just to let you know, I just started into Parkour.
I know who David Belle is, I just hadn't heard of a Nick Belle.
Yes, I can land and roll properly. No, i cant walk on my hands...yet.
Yes, I can drop 15 feet. No, my vertical jump needs work.
And btw, unless this is an AMAZING stroke of luck, the man in the video isnt NBS. And, I have seen that video many many times. But, Parkour isn't about flips and stuff.
Its about getting around obstacles as quickly and efficiently as possible, whether they are physical or mental.
So dont think that I dont know anything here....
