They are definitely out there. And honestly it is hard to find them.. I even know girls who are pretty serious but it only lasts for about 3-4 months then they fade also... Look at the percentage.. pretty low I'm sure. But you can also find healthy women who are not in the gym and are physically fit. I have a friend and she does alot of sports and running and has never been to the gym.. you would never guess.
So don't give up!!!!
