True enough.. I'm having a hell of a time just trying to deadlift properly... however.. I've noticed that I can handle more weight.. even comfortably out of form. Callahan has been helping me.. and I've seen him wince once or twice when I have lifted out of form. Sometimes you get lost and can't see the forest for the trees... As soon as I feel uncomfortable (unnaturally so..) I figure I've hit my limit..
Bob Peoples, one of the greatest deadlifters of all recommended the use of a rounded back when deadlifting. I am not going to go that far but "perfect form" is an ideal not based in reality. There is more than one way to perform all exercises and the most important factor is that you don't feel as though you are placing yourself at risk for injury. You know better than anyone if you are placing your body in a poor position.
