I doubt if it`s possible without cramping or getting injured,but good luck dude.
I figured that as well. I've set that goal just as of today. Soemthing diff to do. I've never seem how much I could do and Im still gaining weight. In college, I tried what this one guy was doing, 250 diamond pushups---broken up into 50s. Got a very good pump. Did these each night, to the point where I had 50 pounds of weight in a packpack.
Yeah ND, the lactic acid is going to be the kill shot for making this goal. And then it also matters if you have a straight bar or EZ curl bar. I am doing a experiment now with the straight bar (the one with the scrw on collars--100 lbs set), my wrists are already taking a severe beating. I have small wrists, my EZ curl bar is better, but I think that my forearms will adjust and grow.
