Of course we all know some country´s or races have better genetics like Brasilian womens can win all fitness show easy , Cabo Verde men´s even without training most of them look athletic and if they go to bodybuilding is almost impossible to beat them because of the shape, roundness, muscle bellies, small waist ( they born to be athletes ). But like BIGDADDY says all country´s have someone with good genetics . Look at me Portuguese and with crazy genetics ;)
But today is not only genetics because some years ago country´s like china dont have good bodybuilders . Is the knowledge we have now , better gym equipment , better and new drugs ( sarms , peptides and others ).
This Hong Kong athlete is incredible , and i can garanted is not that big or heavy but is density , hardness and symmetry makes him look like a perfect beast . What a level we have today.
