The best Results that i ever had was doing shrugs Db and BB. My Traps and my back just blew up. I don't do them much anymore because they got to unprportional. Now heavy Deads keaps them in check. Lower reps 6-8 squeezing at the top for shrugs
Maybe I will do a few sets of shrugs EOD to see if they catch up. I tend to split my workouts into 5 days. But I like doing abs 3x a week, so i will add shrugs to that too.
