Hate to break it to you guys but so long as you're pushing the compounds (squats, bench, deadlift, military, dips, rows, chins, cleans and the occasional sit up and curl) where you end up in terms of symmetry/muscle exaggeration depends totally on what your ma and pa gave you.
I don't see the point bitching traps, legs whatever, because assuming training and diet is covered no amount of isolation work will change it and why would you want it to? it makes you unique.
