Women don't want to look muscular, if they lose too much body fat with decent muscle mass that'll be the effect.
It's a masculine look, personally I don't like women to be muscular. Fit an well maintained, yes, but not muscular.
I'm not aiming for muscular myself (I'm a dude) but I exclusively do weight training, I just figure I can maintain sufficient bodyfat that it won't show through too much.
