Aww, Ryan. It's fun. I led a learn-to-spin workshop on Saturday for people who wanted to get over the initial shock of attending a spin class. Forty minutes of the class was spent simply getting the participants set up on the bikes. The class can be overwhelming (depending upon the sadistic tendencies of the instructor), but I always tell people that it takes about three classes to feel comfortable with the equipment. It never gets easy after that, but it does get bearable.
One thing I do notice with new participants is that people generally use too much tension when they aren't familiar with the class. Try it again, but don't be so eager to make your legs burn. The cardio benefits from the class come from learning how to handle variable, unpredictable intensity. It's almost impossible to do that if you're treating the equipment as if it's a leg press.
