I played league baseball, basketball, and soccer starting in grade school, started lifting in junior high, and wrestled in high school, which involved a lot of running and gave year round access to the school weightroom, including daily during PE (wrestlers and football players solely weight trained for PE), so working out was always natural. I never really thought about doing it to get chicks.

Same I ran cross country and wrestled and lifted during the summers with the football tards.
I used to do it because I hate football on principal and one of my favorite past times was benching more than they could so I could tell the coach no, I won't play on your sports ball team.
