Annoying Spinning

My Tuesday night spinning class is becoming increasingly annoying. I don't know what it is, but this instructor just irritates the crap out of me, and, no, it's not just because she's hard. I think the thing that bugs me the most is how she revs up the speed on the music she's playing when she wants us to go faster. Rather than trying to coordinate the intervals with the natural tempo change in a song, or play a song that is appropriate to what she wants us to do. This is particularly annoying if you like the song. I hate the way she has us doing some hard intervals -- sprinting or hill climbing or something, how she has to talk through it constantly reminding us of form or speed or whatever. It would be one thing if it was mentioned sporadically through the interval as a reminder, but to talk constantly through it I find distracting. She has also started doing this new thing where we do an interval of upper-body movements on the bike. This pisses me off! It is not a spinning position -- I find it utter bullshit and refuse to do it. Also, one of the things I really like about spinning is that it is very simple, there are no complicated choreographed movements or gymnastics and this new crap compromises that attitude of the class. Additionally, she always goes over on class time and she never tells us how long, or how many sprints we'll be doing in any given time period -- thus I never know how to pace myself. I'm thinking of dumping her class, it all annoys me so much.
