Diet and muscle mass: To gain weight you have to consume more calories than you are burning. Do this in a healthy way though. Don't choose junk or fast food. Keep a well balanced diet and make sure you are getting all the nutrients you need. Don't cut out exercise as it is very good for you. Weight lifting and other muscle building exercises can help you increase your body mass.

Fitness: Chances are that you're light-framed and will gain muscle mass less readily than other men. That's fine -- many women prefer this, as long as you're lean and aerobically fit. Hit the gym hard and watch what happens. The only supplement should be creatine. Casey affleck (photo) has your type of body and tonight his movie's opening as a hit. Enjoy your genetic heritage.
