great advice on deads and cleans. ever since making these a mainstay in my workouts my traps have grown more and more.I have found that alt deads and rack pulls and alt full clean/press with power cleans has helped alot. i like to do those and then do high rep stuff like DB shrugs, DB pulls into the armpits,cable rope rows to the neck(getting a good flex in the romboids).you can also try progressive pulls where you start with a couple of full clean/presses add weight do cleans add weight do high pulls add weight do deads until you cant go anymore.but beware of overtraining as these really tax you.do them every other week use squats on the other week 20 rep heavy bar resting on your traps type squats. good luck and may your traps grow over your ears!
