i watched your video on building massive traps. btw, your traps are insane! my traps have responded really well to deadlifts, but i recently started doing shrugs. i do exactly the kind you mentioned -- the dumbbell shrug with holds at the top -- but now this sounds like a waste of time.
my question is this: it's very difficult to get a power rack at my gym in order to do barbell power shrugs. is there any way to get the same benefit using dumbbells? DBs would be the easiest option for me.
