^^Right.
Basically, trying to talk to a girl at the gym is a recipe for disaster.
I'd say stake out a nearby coffee shop to see if she stops by there after hitting the gym, and strike upo a conversation there.
Or, just forget the whole thing and go home to catch up on back episodes of Game of Thrones.
I've never tried it but I have NEVER heard of a couple who got together at the gym. I've only heard of rejection because women don't want to be hit on at the gym. PERIOD. That is why I said don't do it, but if you do try and time it for when she is done and leaving.
