Oak, I echo your statement. While the instructors at my gym don't do anything egregious, there is not attention paid to people who need to be shown modifications. It gets my blood boiling, because people often end up doing stuff that is either harmful, or not enough. And, there's the thing about warming up and cooling down. At 5:30 AM, everyone keeps to the time schedule, but warm up is often compromised. The spin instructors see the one hour as an hour of spinning. They all go over time, starting the cool down when the class should be over, or say to do it on your own. Yesterday, the instructor (boot camp) said, "I know I should stop at 20 after, but I just can't help myself!" Oy, the class is for the people, not you. What's so hard about keeping to a schedule? I never had any issues with this. But, they get away with it, because as you said, most people don't care!
