i've watched a lot of training videos on weightlifters. i rarely see them bench or anything like that, but they probably just don't record these exercises as much.
i know the chinese lifters incorporate a huge amount of retardedly worthless exercises, including all sorts of random abs stuff and funny gimmick shit nobody even would think to do over here. on the other hand you have the bulgarian style which is to do like 5 exercises only, ever.
basically, over the years, i've come to the conclusion it's all a bunch of shit. there is practically no factor that is consistent across all the various samples. i've even heard of a guy who had 34 inch quads by doing 135 on squat for 8 minute sets, nothing else. i tried a version of this for myself, using 115 and my legs got bigger, if anything (definitely didnt shrink). far from "usual bodybuilding" fare and could be explained away 100 different ways by the dogmatists, but in the end these people usually haven't tried it for themselves. how can one even really measure and test all the different theories? you can't, in practice, so all the hardcore HITers or volumers or doggcrappers or Tnationers or whomever are basically mindless zealots.
