All about the food!  To gain muscle you must eat more than the average person.  Some bodybuilders eat in the upward side of 10000 calories a day.  Protein is a key building block for the muscles, so be sure to consume as many grams a day as pounds you plan to weigh.  Don't leave out your carbohydrates either, they are your main source of energy.
