Bulking and cutting are the opposite of fat logic.  You don't mind gaining a little fat to maximize muscle mass because gaining muscle is hard and losing fat is incredibly easy. And 10% is pretty low, unhealthy low for women. We shouldn't go the opposite direction and declare medical science wrong in that it says healthy is too fat.  Healthy body fat is what medical professionals have determined it to be, not some arbitrary number we think sounds nice. We are superior to them in every way. We should act like it.
