Build Muscle Fast - Make Sure You Have Enough "Raw Materials" to Build Muscle

You have to eat big to be big. Making sure you have enough calories to grow is one of the fastest ways to build muscle.
Do not run out to the nearest McDonald's just yet, though. The trick is to eat enough, without eating too much! Sure, you would build muscle fast. However, if you eat too many calories, you can be certain that you will put on fat as fast if not faster. Building that new muscle will not do us any good if it is covered by two inches of fat!
A good rule of thumb to calculate how many calories you need to gain muscle is to multiply your lean body weight by 19. For example, a 220 pound bodybuilder with 10% body fat would need apporimately 3,762 calories per day (220 pounds x (100%-10%) x 19 calories)to build muscle.
Eat big to be big. Getting enough calories is definitely one of the fastest ways to build muscle.
