No, it's nothing to do with circumstances like that, black people typically don't have the joints for it, also something about just outout at heavy heavy level, they are bad at swimming too, thicker skeletal frame I think
Btw even. Top athlete David goggins talked about this on Rogan, it's all pretty well known. Black men only make up 1% of the navy seals while being 7% of the population, David goggins had to try 3 times to get in to th3 seals, kept failing the swimming part, he said he had a disadvantage because he's black and they struggle with swimming and certain activities like that.
As far as weight lifting goes, it's all white and Chinese, I'm telling you right now I'm sure there is a black dude dying to become the world's strongest man, who wouldn't want to be, it's just hard at the highest levels. Just like you won't see those super strongmen from Iceland being the best 100m sprinter anytime soon.
