Not at all! Women will definitely build muscle when they lift weights, that's why people who tend to not know much say you will get bulky if you lift weights (or will start to look like a man). The type of muscle you will put on will NOT be the same as men. It will not make you look masculine instead it will actually make you look more curvaceous and it could actually make a waist look smaller and boobs look bigger if that's your goal.
