Yeah, this might belong in the powerlifting forum, but i'm guessing it might very well be common knowledge over there and i don't want to look foolish, but do want to help a few people out. Anyway, i had been stuck at 315 for a LONG time as a max point (i try to test every other month just to check my progress) and was able to throw up 325 out of the blue by making one change (this was after failing one it once). It may very well have been the placebo effect, but i'll post the tip, along with the explanation i was given as to why it works in the hopes it helps someone out as well in the hopes i get some feedback as to whether it actually worked for anyone else.
Anyway, here it is: Immediately before attempting this max, set up a barbell off to the side with a weight you can row with pretty strict form for about 10-12 reps and do about 7-8 reps with the hardest squeeze and longest pause (within reason of course) you've ever done on this exercise...the whole point is to absolutely tighten and pump your lats. IMMEDIATELY head under the bench without any real rest (just catch your breath quickly, maybe 30 seconds??) and make your attempt. Apparently, as it was explained to me, this produces a rubber band type effect - your lats are so tightly wound if the rows are done right that they kinda create a springboard action on the bench, really assisting you in gettign some good force off the initial explosion, since low rep benching will (as i've discovered when they become very sore after a low rep chest workout) incorporate the lats to a signficant degree. Again, it may very well be the placebo effect, but it seems to make sense to me and I'd like to know what other people think...especially if you try it yourself.
