Tip: To build a bigger, stronger physique, get your protein

You need protein for your muscles to grow; the more, the better. Include lean red meats in your daily diet, as they contain the right nutrients to make muscles grow. It is actually quite simple: the combination of a high protein diet and the right kind of workout will make your muscles grow like you never thought possible.

The general rule of thumb in bodybuilding is that you need a minimum of 1-1.5 grams of protein per pound of bodyweight to build quality muscle. (eg: 180-lb. person needs to eat between 180-270 grams of protein per day).
