My gym is not a great place to meet women. There are a few more of them in the cardio room, but most of them are in the middle of their workout and like Reto says, you never know whether or not they really want to be bothered. What's more, many of them have headphones on, partly because you need a pocket radio tuned to AM in order to listen to the T.V., or they may have a CD playing. I'd feel very weird about walking up to one of them and starting a conversation, even though I know this is probably what I should be doing. You don't see very many people doing that anyway. It's not a social atmosphere. You go in and the radio is playing over the loudspeaker, and if they turned it off, I swear you'd hear a pin drop in there.
Down in the weight room, you'll see a woman come in every now and then, but it's mostly all guys. When a woman does come in, all the guys start trying to talk to her, because she's the only one there. By the time I get up the nerve (which takes a while), she's already had a bunch of guys talking her ear off. I'd be less likely to make an impression on her, since most of these guys are tall, muscular, outgoing and flirtatious and I'm this skinny, shy kid (well I'm not really a kid, but I look like one).
There are a bunch of girls who work at the front counter that I know pretty well, and most of the staff is familiar with me. None of them are single, though. This weekend I am going to a party being organized by the gym. I was going to take a date, but I just found out that's not gonna happen. Hopefully it will be a good time, although I'm trying to be careful not to go there expecting anything, because it could keep me from having any fun.
