Hey Fellow Instructors and Spinning Students

I had to "audition" for a spinning instructor job, and the main critique of my style was that my endurance class wasn't what mad dog recommends. So here is my question:

How CLOSELY do you follow Mad Dogs guidelines. i'm not talking about contra-indicated movements, just the pure definitions of the types of classes. For instance, for an endurance class, the recommendation is a seated flat. Not only do i think this kind of boring but so do the students, plus any long slow distance ride wouldn't necessarily be on a flat the entire time, especially around here. I don't see a problem with telling the students to maintain that low heart rate, but add in some climbs or even jumps (done very slowly). The key is to use breathing effectively to maintain low heart rate. What do you think, what do the students think? Do they like an hours worth of seated flat?

Thanks!

Have a great day
