Not necessary, it can be supplemented by other normal foods, but it is not easy to meet the required protein intake requirements. Eating six eggs a day is still quite uncomfortable.

Protein powder safety problem, regular protein powder is safe, I have been using protein powder for almost two years, and there is no problem. I usually add some creatine.

Of course, if you don't eat, you won't lose muscle, as long as you ensure adequate nutrition.

The principle of building muscles through exercise is to tear muscle fibers through weight-bearing exercise, and then repair and recombine them to achieve the purpose of building muscles. Repairs need a lot of protein, so eat more protein than normal.

Muscle gain requires a reasonable plan, such as:

Monday: chest, triceps brachii, abdomen

Wednesday: Back, biceps brachii, abdomen

Friday: legs, shoulders, abdomen

Arrange two movements for each part, and then do three groups for each movement, with each group 10- 12 strokes.

One of them should pay attention to exhaustion, that is, the last one is basically impossible to do.
