For the Nollie you don't have very good at anything except standing. This is a very easy trick and if you can Nollie high and over stuff it looks cool. Plus, this trick also helps you with combos to rails, and jumps. 

    You can do this trick standing and riding. Some people like to practice on carpet in their home, but this doesn't work at all. There nothing alike. First, put all your weight on the nose off your snowboard. And try to lien forward as far as possible, but without falling. It might take a  long time to get your balance perfect, but after it if really help you with lots of things. Also, when you are leaning forward, do it straight forward, not to a side. Then hold your balance as long as possible and then go back flat on your board.
