Running doesn't build big muscles, she doesn't know what she's saying. Cardio helps you lose weight and weightlifting helps you build muscle. You can lift weights though. Girls think they are going to get huge by doing it but its not true. Even if a girl got big from lifting weights it takes a very long time. You can always talk to a trainer and they can get you on a plan that gets you the body you want, its what they do.
