That's probably why the DC method is so effective. It seems to combine a bit of what could be termed powerlifting into the mix. You always do squats and deads. Since increasing my squat poundage, it has spurred more growth everywhere else overall.
I love doing really heavy shrugs, and it has increased my grip strength a lot, too. I'm now up to 405 on the squat, and I love to see people's faces when I'm putting on the weight because they seem to be in total disbelief that anyone can squat that much in my gym since I seldom see anyone doing squats.
