I usually like to do 4 sets of trap work going very very heavy, I read that years ago. Trap should be lifted heavy because doing them light is kind of a waste of time. This is my setup tell me what you think:
60 pounds for 12 reps
80 pounds for 10 reps
100 pounds for 8 reps
Then a last one 120 pounds for 6 reps.
