I pretty much disagree with all this. I think legality absolutely has everything to do with it, I don't think anyone would talk shit or insecurity has anything too do with it, look at JP.
Genetics means a lot but won't take you far at the pro level without everything else being on point. It's not about how hard you train or don't train, it's about figuring out what works for you. I don't think anyone on a pro stage has pathetic training. Shit diet except for a few weeks before a show? No way. And female pros train hard as fuck. Sure some people train less intensely and do more volume and vice versa. Shitty bodybuilders are shit because they train and eat like shit. Even with bad genetics, you can build a great physique even if it's not "bodybuilding stage" great. Dorian had great genetics just not "perfect" ones. Arnold trained like a beast, and what Dorian was doing in the gym was crazy intense, you CAN tell from his videos. 6 reps with 400lbs and 1 forced rep when you are all out focused on the muscle and not just moving the weight could easily be crazy intense, without that intensity he might have only done rep. He's clearly not a strong bencher, that has nothing to do with bodybuilding.
I mean I can see your points and agree with them as well. Someone posted Dorian's routine from blood & guts on another forum and asked to please point out the superhuman effort required to go through with it. On paper it looked like nothing special. How Milos' training was so much more "intense." I pointed out that Dorian, and other HIT trainers, put an enormous emotional investment into those few sets, and that you can't see in a written out program. Fact of the matter is that Milos' trainees simply can't put forth that type of effort into each of those giant sets, it's impossible, even if they supposedly go to failure and beyond each time. So yes, Dorian did train hard. I'm partial to this type of training myself. Or like what Jordan Peters does.
The pro I mentioned looks like nothing between shows, he just relaxes mostly. Then he turns it up precontest and just mutates within days. But the training is nothing out of the ordinary, like any number of regular gym-goers. Me and my friends do wonder what he could have done if he trained crazy hard, like a Jordan Peters. But then again he might have burned out or gotten injured (which is actually a guarantee when training like that).
The females are consistent with everything, train strictly, it's just that they don't have the same ego with loads and progression that a lot of guys do, they don't "strain" crazy hard. Just goes to show that if the hormones and food are there you can build a great physique without annihilating yourself in the gym, to echo Lee Haney.
Regarding pros being shamed if admitting to all of it. I think it happens, even on this board if we discuss someone like Dallas carver you inevitably get the comments of "yeah but he was on 10 grams of test." If someone were to admit to something like DNP you inevitably get the comments of him being lazy. So you leave things out, you don't mention everything. There is a lot of shit talk even between bodybuilders themselves, between gurus. So and so is abusive, so and so is shooting too much SEO, that pro/guru is abusing diuretics and on and on.
BTW, I read that Hadi Choopan had threatened to sue Chris Aceto because Aceto pointed out the site injections. Someone said Hany confronted Chris at the O and said Aceto cost Hadi placings. So would someone like Hadi admit to SEO because no one would care? Of course not, he will never admit it.
