how do some people do foward spins so fast, and so many times? i can do it without using my hand but not as fast.
It is the same both directions, most people are usually only strong in one direction. It really just takes practice. I actually prefer to do reverse 360's going right and I find them easier. I slide up on the board as I approach the lip and shift my weight back at around the 180 point.
Center your weight, make sure to get a good starting snap, the more or less take car of themselves. I learned with my hand though, but riding drop knee, using my hand wasn't a choice. Its kind of one of those things that once you get it, you got it, but while you are learning, its kind of mysterious.
I always use my left hand but sometimes if Im lookin for a little strange I'll switch it up and use the right. I never tried spinning around in circles on my belly while doing it though. Sounds kinda gay. I always prefer to smack it standing up.
