There is always confusion when it comes to protein and the gym. Where as most men believe that lifting a couple of dumbells and wolfing down gallons of shakes they will look like Jay Cutler in a matter of weeks. And many women fear that protein and weights will get the similar Jay cutler look and maybe grow a pair of balls along with the mass (Not literally guys) But the truth of the matter is that no matter what form of exercise we do, protein plays a very important role not just in building muscles to be bigger, but to also aid in recovery to help prevent muscle wastage. But the key area of worry/desire for people hitting the protein is mass? Will get get huge? The answer..... Not really. The reason for this is down to training intensity, calorific and macronutrient intake, calorie expenditure, testoreone levels, rest and recovery to name but a few. Its not easy to pack on size. But in terms of Protein being a good guy or bad guy, hands down he's a good guy.
