It makes no sense to me to turn the music volume up to max and then have to yell over the loudspeaker. I hate that. Additionally, our spin bikes are monitored with a display available to the instructor. In my 80's, I do not need to be monitored any more. I was monitored when I worked. No more of that for me. I sometimes set my own speeds and goals to match my fitness/energy of the day. Best result for me was to quit the spin class when I can't get out. and ride a spin bike on my own
