I use to work traps once a week on Fridays (shoulders, traps, calves). I use to have overly developed traps, I then heard I believe it was Neil Hill talk about not getting the traps so developed that it hunches you forward with your posture, that's EXACTLY what mine did which is counter productive to bodybuilding which you want to be upright and wide and you can't properly do that with overly huge traps pulling you forward.
Pic is when I was around 250 lbs and shrugged very heavy weight and deadlifted all the time you can see im natural hunched over slightly due to my traps
