In such situations I've found that the best thing to do is hit the iron. Pile on the plates: low reps, cheat a little, squats, shrugs - big weight! Grab that bar and feel the knurling bite as you blast through the pain while roaring like a BULL GORILLA!!

After you're done, find a nearby mirror, put on your most feral expression, crunch into a flex of every fiber in your body and shout "BEEEEFCAAAAAKKE!!!!!"

I guarantee results.
