my traps grew real easily, i think the best exercise is the dumbbell shugs, i just do 4 sets of these at the same weight for 8-10 reps, at the end of my back workout, i also have exercises during the week that traps are a secondary exercise such as dead and upright rows.
you want to really fry your traps?.....this is my trap work out for 2 sets.....dumbell shrugs..130's to failure.....100's to failure 80's
60's all the way to 40's for 2 sets
then i shrug with a barbell for 2 sets to failure usually with about 350. after that shit i cant even touch my traps the next day they hurt so bad let alone contract them
but you really have to put in a head turning ball busting effort all the way through
