Whether before or after fitness, many people generally follow a rule, that is, to have a cup of protein powder (there are many choices on iherb), in order to assist muscle recovery and promote muscle synthesis! In fact, after training, not only protein should be supplemented, but also carbohydrates should be supplemented. Whether it is to lose fat or gain muscle, it will be helpful to take in the right amount of carbohydrates after training!
So why eat carbohydrates to gain muscle? Because our muscles store a certain amount of carbohydrates, which is muscle glycogen. You still need it to provide energy when you exercise. But when your carbohydrate intake is sufficient, muscle glycogen is also sufficient. Then your intake of protein can be used for muscle growth. At this time, the muscle gain effect is very good.
