Why do niggers have good bodies?

I always wondered by niggers have such muscular bodies, even when they seem to be doing nothing at all. nothing at all. NOTHING AT ALL. NOTHING AT AAALLLL.

is it something in the genes? Also why do they have big cocks.

Its not 6, its 5.5, 6 not being outside the first standard deviation. I think 5.5-7 is normal with 5.5 being average.
