Spin classes are ALL about the music ,in a way, choreographed somewhat to the rhythm and pace of the music. Hopefully, something you like. And almost always, played way too loud for my poor ears. Some instructors have ask you to do alot of standing out of the saddle, or do quick intervals (off-on-off-on the saddle in rapid succession) I just modify, the quick up-down stuff hurts my knees, and prolonged out of saddle "climbing" isn't my cup of tea either. Hope you like it! Did anyone mention bringing your water bottle? You will sweat alot. tokie
