LMFAO!
Going mad old school with the Goener brick exercise. Seems to me it would be quite great for the grip, forearms, biceps, back and stomach muscles once you are holding enough weight.
You can do alot more than 2 bricks Andalite. Off the top of my head when I was in construction I could pick up 2 stacks of 5 bricks without too much trouble and carry it a distance. Granted this was leaning it against my stomach,chest, but I could pick it up off the ground unaided.
I know for a fact you are stronger right now than I was back then except for in the grip.
Go for 2x2 brick next time amigo. I wouldn't be surprised if you go up a brick a session.
Hex head dumbell lifts is possibly the best all around grip exercise. Might give that a shot.
