Just my experience on spinning...my favorite instructors are the ones that teach part of the class off the bike. They will walk around and make suggestions or encouragements to the group in general and people specific...I think it is the way you do it. The thing I DO hate is if they change my tension without asking....NOT ACCEPTABLE. But checking cadence, form etc is great. Just a quiet "good job" when you are working really hard is nice.

I have found the instructors who don't get off the bike seem to be more interested in making the class their own workout and the class is along for the ride so to speak.

Not saying that any intructors on this thread are like that, just the ones at my gym, a couple of them in particular.....
