The important thing to remember is that women can NOT get big and bulky because we do not have the testostorone that men have to make muscle. What happens to women is that they have fat on top of the muscle, therefore thinking that their arms are big, but really it's the fat on top. This is true for all part of the body. So what you have to do is to find a balance between cardio, weight training and eating healthy to get that lean toned look that women want.
