Sounds like in your case they couldn't understand why anyone would be using those equipments and weights because they are unable to.   Also, if they would intelligently do those things in the rooms, who would behold their beetusy glory?  These two were doing weird "exercises" with the 5 lb weights and shaking their limbs after every "set" like something was accomplished.  They weren't even doing 3 sets of a specific number and I was unable to nail down what muscle groups were supposedly being used.
