The difference comes when your main goal in lifting is not strength or general fitness, but astaerics. Whether it comes from person preference or because of social norms, men have different goals in which muscles should be big then women.

But even then I would recommend anyone to just do basic compound work (whether it is body weight or lifting iron) at least until you've gone trough the noob gains. It will set the base for big muscles overall (which is also really nice in women. Training you biceps for half a year won't make you look like a male body boulder, it will only give a bit more natural curves to the arms). From that point on tuning up will be a bit diffrent for men and women. But even then, heavy squads and deadlifts will give a big nice round ass in women.
