Indeed, like shadling21 give me some internets and im good to go. I havent had a chance to use one yet, but they have these awesome exercise bikes at my girlfriends gym. There are multiple bikes all lined up next to each other with a screen on them, and its a racing game simulation. So you get to race the other people in the gym. When you go up hills in the game, it gets harder to pedal, downhill it gets easier and so on. Great motivation to exercise, after all who doesnt like a little competition.
