Well, you know, there's this french thing called Parkour and there's some clubs around. If you're that interested seek out them. I, however, have no idea what I'm doing when I have to coordinate my arms with my legs.
This isnt something someone can just tell you how to and you do it, it requires practise. Asking how isnt really going to help, you need to find someone how can do it and they can teach you over time and you can see how its done and they can properly explain.
Try to land on your head when you feel like you're going upside down when pushing off, believe me if you aim for your head you'll land on your feet always! :thumbsup:
