What are you doing Vince, you can't just tell a guy to eat 500 more calories. You can't just tell a guy to do difficult exercises without telling him how to do them properly.
Spider, if you want to grow muscle you do have to eat more. But you have to have make sure you're getting a lot of your calories from protein. Aim for getting 1g of protein per lb of lean mass that you want. For instance, if you want to be 200 lbs and 10% body fat (that's actually Zacked, but this is a goal), 20 lbs of you will be fat and so you want 180 grams of protein. That's 720 protein calories, as 1g of protein = 1g of carbohydrate = 4 calories (1g of fat is 9, btw). For the other 1,280 you should divide them more or less evenly between carb and fat. Don't worry about it as long as they're close, but remember that a gram of fat has 2.25x the calories of a gram of carb. And it will be fine if you get extra protein and split the rest. Drink water.
