Here is a link to a highly popular article by Charles Poliquin. I suggest that for all of you wanting to build muscle, and stay lean whilst doing so, take note and begin your day with the true breakfast of champions. For those of you who find steak first thing in the morning, difficult to stomach, start off with ground meat products like beef, turkey or lamb mince. A great article, and a great place to start learning about nutrition.
