I agree. I'm working out now, not because I think it will help me lose weight, but because better fitness is part of my goals. I want to be skinny, sure, but I also want to be capable. My workouts are brief and I avoid anything like running, because I'm still too big (IMO). But I'm gradually building a little more muscle and gradually adding activities.

If I keep this up, when I meet my weight goal I'll have a lot more muscle--which ups one's metabolic rate over the same pounds of fat. I certainly think that would help maintenance.
