Spin Instructing

I attended a Spinning Orientation this past weekend because I'm looking to become an indoor cycling instructor. I really enjoyed it (other than sitting on a hardwood floor for 3 hours). I hope that I can start sometime soon while the inner fires are burning brightly. I do have confidence in myself, but I know there are some tough things to deal with when being an indoor cycling instructor (i.e. workout types, music selections, etc.). I know I won't be the best right off, but I do hope that I can challenge my class and help them to improve their fitness. Oh, by the way, I will be performing different workouts each class. I've attended some classes that do the same workouts every single time. That's cool if you only hit the class once a month or so, but once or twice a week--UGH!!!
