Don't stand chatting with your mates for over an hour whilst simultaneously taking up space at the dumbbell station/bench.
Don't talk and walk, treadmill and mobiles don't go together.
Don't spread your snotty germs all over the barbell.
Don't forget to wash your hands after you've had a leak, before returning to that barbell and/or machine.
