If I worked out more, would girls like me more?

There is this girl I really like and I rarely ever get to talk to her. She always ignores me and talks to the jocks. Right now I am in cross country and soccer. I'm good at these sports but I still don't have big muscles or six pack. Is this what girls really want. If I were to spend three months on P90X or some weight training program to get a six pack or big muscles, would this make her talk to me? This has been an issue and I was wondering if this is all I had to do to get her to talk to me.
