The Rippetoe thing just shows how weirdly desperate people are to believe that bodybuilders do everything wrong. The misconceptions about how it's all just pumping up without trying to get stronger absolutely mystify me. How can people believe that?
With clockwork regularity we have guys coming on here talking about how bodybuilding training doesn't work for naturals despite the multitude of professional drug-free bodybuilders we have on this site alone. I saw a video the other day with Tate and Wendler talking about drug free vs assisted training and they made the point that there is no training system out there designed with only steroid users in mind, and it's so true!
But no; natural lifters have to train more often because they need to activate muscle protein synthesis more frequently, and you have to lift heavy at the start of the workout to activate the muscle building machinery. There's no point in natural lifters doing lateral raises (@dt79 - remember that conversation?) and don't even think about training to failure because there's no way your puny natural body could ever recover.
I just can't get my head around why people are so unwilling to believe bodybuilders are doing things right, whether they're natural or otherwise. Seems every time you question them the answer is always just "steroids."
