Fit healthy women do not look like body builder women. Simple as that. They need to bulk and cut, like any body builder, as well as (often) take hormones to build muscle that normally does not build easily on women.

You don't see rippling muscle on female pro wrestlers or fighters, you see fat, albeit just a thin layer of it layered overtop the muscle, smoothing the lines and softening the form. Musclebound looks do not come naturally to women.
