if you are going in there balls to the wall like a gorilla and throwing weight around then it will eventually catch up to you.. there has to be a method to your madness.
it is no different then a runner who does nothing but interval training everyday. it can actually hurt your speed and not help cause injuries can mount.
i'm all for killing that shit every workout, but you have to give your muscles a chance to recover. you can't just go in there and bench everyday 1-2 rep maxes and not expect to create imbalances and injure yourself. we are humans, not robots here.. why do you think NFL running backs break down so young, rarely do they make it into their 30's worth a damn. its cause they take a pounding every play blocking and getting hit
