Another thing about this sluggish gal at the gym... toward the end of the class, she keeps yelling out stuff like "Oh, yeah!" or "You go!" Something like that.
I don't object to that per se. Like I said though, she's barely moving in these classes! Why in the world would you let loose with these yelps of enthusiasm if you're barely moving at all? I'd rather that people put their money where their mouths are, so to speak.
