How do you know what 'most people' do in a spin class? Loads on most spin bikes are adjustable and it's not difficult to simulate outdoor road conditions.
Spin classes seem like a reasonable way to get in an hour of intense riding when the whether is dreary. I don't think many riders goes to spin class for a relaxing easy spin.
