It's been so long since I did shrugs, I don't even know how much I could do. I've gotten much better trap growth since I (re)started doing deads than I ever did shrugging heavy weight. I *think* last time I did shrugs I did 315x12, 3 sets, squeezing all the way up. But, I have to use straps to do that much weight b/c my grip is so weak.
