Chimpanzees in the wild have between 2% to 4% bodyfat.
Bodybuilders after 3 months of dieting and tons of GH step onstage at around 5% bodyfat.
And whilst bodybuilders' muscles are larger than those of chimps, chimps have twice as much muscle per volume of area than humans because they have far less fat between muscle fibers than humans. When you are at 2% bodyfat with twice the muscular density of a human being, your muscles are going to look insane even if they are not very large.
Gorillas in the wild have the same bodyfat and muscular density of chimps, except that they have between 3 to 5 times the total muscle mass of human males.
