There is some pretty convincing evidence that post workout protein intake improves muscle recovery and growth. This is just one of many research studies that support the notion of taking in a good protein potion before and after your workouts.
Protein is the major structural component of every cell in the human body. The word “protein” is thought to come from the Greek word proteios which means "the first quality." Protein is a very important dietary nutrient and many people do not eat adequate amounts of it or the most nutritious forms of it on a consistent basis. This is not such a good idea as you'll learn shortly.
