None because West African Bantus (aka 95% of nogs you are gonna meet) aren't genetically better at weight training. They are slightly better at running from more fast twitch muscle fibers (really Nilotic/Eastern Africans are far better and make up most Olympic winners tho), but this does nothing for the upper body. They do generally have less body fat than Europeans though, no winters in Africa.
Europeans are generally the best at weight lifting and upper body strength. Simply look at lifting record holders, its mostly whites.
