BadLad: The Polynesian based islands do seem to produce a more selected breed of muscular and strong humans. Being born in American Samona I can be witness to this. But not all of the folks are gifted, some of the women can only handle 300 for 12 reps when they first try benching....the shame & pity of it! My two cousins (while in high school) could bench easily 400+ for reps , though they didn't bench often. Each could also clean & jerk press over 300+, which was one of their main exercises for football. The Mormon church (which is far spread in the Polynesian Islands...including New Zealand) brough a lot of the brothers over to the mainland. Not just to set the path to save their souls but to play football for their major football factory's...BYU, Utah St, Utah. This can also include USC/UCLA (though not Mormon schools) where quite a few of my friends and family attented and played.
A lot of German speaking, Scandinavian and Eastern Europe countries (and people(s) who's names end in a vowel) produce very strong muscular people. As well as American Black people's. Percentage wise though, from a much more smaller entic group, the Polynesian race (for what ever evolutionary reason) do seem to produce a better gene pool for natural size & power. The luck of the draw I guess. Good Luck.
