1. Eat and I Mean Eat a lot
Eating high calorie meals is probably the most important step in gaining mass. If you don't get enough to eat, you won't gain weight. You can't lift like a horse and eat like a bird and expect to gain weight it just doesn't work that way. That is why most bodybuilders eat four to six times per day to increase calories, protein, carbs., etc., and to increase the absorption of nutrients. You may even want to try drinking a protein shake in the middle of the night to encourage additional muscle growth.
