Do you find military press also nails your traps?
Can I ask your main reason for doing power shrugs? Mainly to help your deadlift lockout?
I would incorporate shrugs but I would have trouble fitting it into my workout, unless I did them well away from my military press or else I think I'd have trouble pressing the bar. I'm not sure they're even necessary given I'm probably only capable of a 1rm of 75ish kg on MP and 190kg on deadlift.
I dont feel it in my traps from doing MP. Nothing like power shrugs anyway.
Started doing power shrugs to strengthen my upper back and I would say they have done that.
