What do you want from a Spin class?

I will say I cannot STAND it when they talk too much, it's incredibly annoying.

Agree 100%. I use spin classes as an adjunct to meditation - I "close in on myself" and envision good pedal stroking, staying light on the handlebars by using glutes, etc. I also don't always follow the instructor - I see no need to do a standing climb at a cadence of over 100 because I'll never do that on my road bike.

Music is key. It needs to have a beat that can accompany a pedal stroke. I can't ride "off beat".
