Some women still fear the weight room. The existing myth is that women who lift weights will end up with big bulky muscles and look too manly. Ideas like this are giving resistance training a bad name. We as trainers have to remember that men and women are physiologically different in the fact that the increase in muscle mass that is acquired by men is due to testosterone. Yes, women secrete and deliver testosterone just like men do, but at much lower rates and volume. This allows for women to build tone lean muscle and increase metabolism to enhance weight loss.
