Racism?
Matt Ogus, Bruce Lee... two different styles of mastery over one's physique accomplished both by asians. If your gunna put me on the spot, I'd say that lots of black kids I know personally that are shredded actually have bad diets that are lacking in calories, and BF%=Aesthetics... But I'd highly suggest looking at native Africans who hadn't been bread like horses during slavery... say, in africa. Yoiu'll actually see that their physiques are standard. Your perpetuating lack of results due to inferior genetics because of one circumstance due to a strange social oddity from artificial selection due to slavery. Regarding pro athletes, they are all on gear as well, and the explanation is more of a socioeconomical issue that physiological. These guys may have slighter higher baseline levels of test, but its exacerbated when they are on gear. There's also the common theory that these people grow up in communities that can't afford school, and athleticism is their only method of succeeding, so there is more motivation; additionally they may as well feed into the placebo minset of BBC genetics... Also thinner skin aids in showing muscle... but growing up in neighborhoods predominately black and working out at the rec I can say that this whole genetic superiority thing is pretty much a racist fallacy. Don't be judgmental.
Honestly, you have no idea what those people (gym goers with better bodies) you see in the gym do out of the gym, how they live their life, or how active they are. Am i saying genetics don't matter? No, but they do not make "all the difference". If your don't beleive me you can look at the ranges of testosterone levels in humans... It's hardly variable enough to make any real world difference.
If you want to accept being a dough boy that was born that way- than fine. But the fact is that everyone in good shape puts forth the effort, whether they know it or not. If they are elite status, they definitely work for it. Maybe your problem is you are comparing yourself to unrealistic standards due to seeing fitness models and bodybuilders that are top athletes and users of PEDs. You know people that say this kind of crap never get to an elite level because they accept mediocrity. People that say this kind of crap are betas, and it reflects into a Beta physique.
If everyone could just bust their ass for 2 years and get shredded, the world would be completely different. It takes years.
