Remember the saying that “muscles are made in the kitchen”? It actually refers to six pack abs but it’s true for other muscle groups too. If you want to build a fitness model’s body, following a good muscle gain diet is just as important as working out.
Eating the right foods at right intervals and following an appropriate diet, are the key factors to gain weight. Working out alone is not going to do the trick. You need to exercise your muscles to encourage them to grow, but you also need to provide them with the right nutrition and diet.
