As a guy who's bulking, I worry about this too. I've been skinny my whole life and true nerds have always recognized me as one of their own. Will that change with a lot of weight training?

It feels really silly to type that but I feel the ability to seamlessly fit into that culture is a big advantage.

Like, my fiancee is an attractive latina woman and she is the biggest geek I know, but she feels like she has to "prove herself" to other geeks. I hardly know anything about that culture but they instantly see me as one of them.
