Yes every bodybuilders look like him or more, they look like monsters .
He is a world champion so it's safe to say that he has an edge over other bodybuilders. No doubt, all professional builders are insanely huge, but to win a contest like that you must be comparatively better than the rest or you flex better (the judges look to have lots of criteria that goes into their final decisions).
It's great seeing a Nigerian excel in competitions like this where we do not have regular presence and this could create a path for other aspiring body builders in different parts of the world.
Nigerians are now doing better in sports both in the popular ones and not well popular sports. For him to have won in this kind of sport then I must commend his effort before now.
I think this will be a good start for other bodybuilders who are willing to take a career through this part and an assurance that anything can be possible to anyone who is consistent in what they are doing. $600k may look small to some persons, while to others it's a huge win for them.
