Etiquette for repeat classes/weight loss

[Crankin]

I belonged to the same gym for 12 years. I quit about a year ago; I am sure if I went back there today, I would see the same people doing the same things at the same time of the day/night that they were doing 10 years ago... while it probably doesn't do any good to notice other people's fitness routines and their improvement, or lack of thereof, I did notice. Not much change. Some of the people who did obsessive amounts of cardio were super/anorexic looking skinny and others never lost the considerable amount of weight they needed to lose. The ones who made a change were the ones who varied their routine.
I did notice, though, that many of the original people who did spin only did the classes some of the time, or like me, became cyclists and went to spin only for a couple of months in the winter. The last year I went to spin classes, I hardly knew any of the participants. I've heard they have fewer classes there now. People seem to be into core work, Bosu, yoga, group weight training. I think the spin classes are still going strong with the daytime "ladies" but have lost their appeal for the after work crowd.
