I know what you are saying about 'fluff' moves. At my gym you can really tell the instructors that ride outside and those who only spin indoors. The indoor riders always do the 'hovering' moves and have you reach way out on the ends of the tri bars while standing which I would never do in real life??? That one just makes my lower back hurt so I never do it. I guess when we are in spin class keep in mind not every instructor is well versed so spin accordingly.
