The number one key to success in the gym is to be charismatic(as well as every environment). The last girl I was with from the gym was the hottest one every guy was going after. I did as 240 explained before. However I got to know everyone at the gym. When I walk in everyone says hello to me, I talk to the guy at the desk, I make a few stops to talk to different people, I say hello to the cleaner, I talk to one of the trainers. In between sets people come up to me..etc..
Meanwhile this chick is getting stared at by every guy, I'm too busy to notice her. In her mind she's thinking ''who is this guy?'' ''why does everyone know him?'' ''how come I don't know him?''
This is the type of man a girl wants to get to know. She then approached me one day and asked me 'don't I know you from somewhere', end of story.
If someone like Bill Clinton or Obama walked into the gym, do you think they would just walk in with their head down, stick their ipod in, and ignore everyone? no, they shake hands and say hello to everyone. That's the type of person people want to know.
