If you want to gain new muscle mass, then protein is the name of the game! Protein allows your muscles to recover from tough workouts and rebuild bigger, thicker and stronger. For decades, bodybuilders have grown more and more keenly aware of protein's role in muscle recovery and growth, and thus worked harder and harder to ensure they're consuming adequate amounts in order to deliver growth. When new trainers enter the gym, they will grow no matter what they eat. However, as lifters move from beginner to intemediate status, the need for a steady supply of the macronutrient protein becomes more and more clear, if they wish to continue growing bigger and stronger from their training. The average 200-pound, steroid-free athlete can make use of 30 to 40 grams of protein per meal. At a clip of 5 to 7 meals a day, one can quickly note a few things.
