Thanks for the tips, all of you. I have actually done all those things you mentioned; my hands are about 2" from the pins and I force my wrists straight. It seems to help, a bit, but I still couldn't manage my 3rd set today even after popping some motrin (I know, why haven't I stopped doing them already if they hurt so much.)
I may also omit squats on my mid-week workout as you suggest.
I'm gonna try front squats next workout, we'll see how that goes. I'll obviously have to start with not much weight but it's worth a shot. Thanks again guys.
