Because the muscles of the model are carefully built, they need to be slightly modified after having a certain dimension, such as body fat and so on.
Do not eat muscle gain.
Muscle gain and weight loss are contradictory. You can't run too much or your muscles will run away.
I suggest you drink bsn series slow-release protein powder. If you don't like sweet, switch to something else.
Do not use whey protein.
So my advice to you is 1 year and a half to gain muscle, carve small muscle groups in the first four months, and reduce fat after running for two months.
