The Chatty Kathys
You can probably easily spot them. They only hit the gym with a posse of friends or at least in a pair, and they spend a lot more time catching up than sweating. To be fair, it is hard to find time to work out and hang out with friends, so we don't blame them for trying to multitask. You might want to avoid the cardio machines when they're around if you enjoy working out in peace and quiet, though.
