This is a good exercise for the upper traps...

[Jake LaMotta]

Seated dumbell shrugs. I used to do these 3 sets, reps of 14,12,10 (increasing the weight each set). I got good results in my upper traps from these.

I read in an interview with him, that this is Jay Cutler's favorite exercise for the upper traps.
