Anyone who states that he knows why 100 percent of women do or don't do anything at all has proven that he knows nothing more about women than those of us who admit we know very little.
Fact trumps fantasy when analyzing data, but I fully understand and respect why some fans enjoy the feeling that they are the inspiration for what female physique athletes do with their bodies.
Even if you are able to find the one or even the several hundred women who bodybuild because "that's what the fans want", the total number outliers would be statistically insignificant.
Sycamore is right about many women lifting, because a partner encouraged it. But because random fans on the street or at the market suggested it? That's not really a thing until there is enough data to state otherwise.
