I have been going to spinning classes at the same gym since past September and I have gotten to know the regulars. Some of the regulars are hard-core - if there is a class, they will attend it. There is great demand to add classes, there is pressure to find more instructors. And classes have been added. But the many regulars end up doubing up their classes, doing them back to back. At the end of the day, it's their ride, they paid for their gym membership and it's their choice, as long as the gym allows them to do back to back classes. Don't think it is quite fair to do back to back classes when the classes fill up so fast and there are others who get turned away.

But it goes beyond the fairness: I know some of these regulars, we chat in the locker room afterwards (that is how I know they go so often - I am not constantly there to see it). There is not one of them who is not worried about their weight and trying to lose. I never see them doing weights or anything else that balances our their cardio. A few of them gained weight over Christmas. Yet, they are in practically every spinning class offered.
And I don't see a big improvement in the weight loss. They have all been spinning longer than me. I would have imagined that if you were doing every spinning class you could get into, the weight would melt off.

How common is this? When I got into spinning, I looked upon it as the hard-core cardio way to drop some pounds. But I am seeing more and more than it is only a piece of the exercise puzzle. And isn't there such a thing as overdoing it?
