As far as the training loads go, luki agreed with me that if he went back to powerlifting style training he would probably be even stronger than before with the added mass. But the execution of the exercise is different now. So is he really weaker now, you know what I mean? It's a simple fact that a muscle's strength is directly correlated with the cross sectional area of the muscle. This does not mean you can compare a big and small guy and say, "see the big guy is weaker than the small, therefore load doesn't matter," but that misses many factors which affect demonstratable strength. If a trainee never tries to exceed that "80kg" or never goes to failure he will not be maximizing his growth, simple as that. All big guys are actually strong as fuck, even Paul Dillet. Regarding "failure" it depends. On small exercises you have to spend a lot of time training right at the failure point, and basically everyone does it regardless anyway. If you say you don't go to failure, does it mean you never go to a point where you miss your last cable pressdown or curl or you have to use a little body-English to get the last rep? I've never really seen that guy, advanced bb or not. You can watch Cutler or anyone and they go until they can't do another rep with the same exact form all the time. That's failure. On things like leg presses things change, I've almost NEVER seen a lifter fail a leg press but you apparently don't have to to still get a huge stimulus, for various reasons.
