I'm not a fan of his "Kroc" rows (looks like a great way to blow your shoulder if you don't know WTF you're doing). However, I do agree with stepping back and analyzing your workout to try to figure out why you've plateaued. Simple, but sometimes we forget the simple stuff.
Personally, I've plateaued on deadlifts. I'm thinking of stopping that for a bit, and starting stiff-legged DLs and rack pulls. My lower back doesn't seem to like heavy weight.
