Or Olympic lifting/Crossfit. Crossfitters tend to have mad traps. I had traps from Crossfit, but didn't quite realize how intense they were until I saw my passport pictures from last year, taken just around the time I stopped doing Crossfit and switched to bodybuilding and powerlifting. I looked like an NFL linebacker in drag. I haven't done Oly or ring work since and my traps have significantly deflated. As a woman, it's not exactly a muscle group you want to "pop," so I'm ok with that.
