When you've played indoor all your life, it may be a little hard adapting to outdoor. For outdoor I believe that you'll need to be well conditioned and in great shape to begin with. You may understand the rules real quick, but if you're coming from a 6 player indoor team to a 2 player outdoor team it might be hard at first to get used to having 4 less players.
However, you can also play on 3, 4 or 6 player outdoor teams as well even though you only usually see 2 player teams on TV. Also, if you want to see what outdoor volleyball is all about you can watch women's beach volleyball videos and see if you still want to play. Here are some videos that you may want to try.
