Best muscle/gym file?

[lego]

Hello, I am looking for a file that will motivate me to get massive muscles and become a gym rat. Loving every moment in the gym and even through the pain to push myself. Maybe even obsessed with going to gym and building muscles. I wouldn't mind a dominant or confidence file either. I don't really care for sports but I don't mind it either. And finally I don't want to become dumb.

Recommendations will be appreciated. :D
