So are you saying in order to have a huge deadlift and to be big you need to train your ME with sloppy form each time?
It isn't that simple - the strongest men can often have the biggest bodies, but that 1) doesn't make them better bodybuilders and 2) doesn't mean they train using their ME form in the gym to get to where they are today.
As a bodybuilder, no matter what range i am training in i keep a certain lock on form. So when barbell rowing, i could easily throw another plate on each side for reps BUT i would not feel the muscle working the same. I could easily strain to lift another plate or two in my DL, but i don't care about my numbers enough to do that when i can be more productive for MY goals in the gym. I know that with spotter security i could press around 400 - ass up, wide grip - but i never do, sticking to 300 to keep tension and better form - even in the lower rep ranges (~3~4).
Not only all that but even if i were training for my poundages, i would do so with meet day form!
