I ALWAYS start my classes by reminding everyone that this is THEIR ride. I provide a framework for them, but to do ONLY what they are comfortable with interms of the movements on the bike and the intensity and amount of resistance they are putting out. I unfortunately don't get to ride as much as I did a few years ago (I have an almost 2 year old who wants to see his Dad once and a while), but I have maintained my fitness level with a combination of 2 Spinning classes per week (one as the instructor, and one where I can focus on my workout), coupled with some light upper body conditioning and ab workouts, and one commute per week by bike in the good weather (26 miles each way at 17 mph avg). I think that my cycling helps me make my classes a little more like the real deal, and some of my students, who vanish in April and reappear about now to commute everyday, would probably back me up. Koffee is correct however. Each instructor does have their own style, and you may have to kiss a bunch of frogs before you find your prince or princess, but it is more fun than riding the wind trainer by yourself.
Good luck!!!
