First of all, you should understand that abdominal muscles also belong to muscles and can be enlarged through heavy and high-intensity training. Secondly, supplements and high-protein foods are the sources of our muscle gain. Take protein powder as an example. The recommended eating method is: take a spoonful half an hour after exercise and a spoonful before going to bed. Because these two periods are the end of muscle movement and the peak of absorption, we can achieve the effect of muscle gain through nutritional supplement. Therefore, both abdominal muscles and other muscles can be eaten in this way. Eat a small amount of digestible carbohydrates, such as bread, before exercise to provide the necessary energy for exercise. I hope to adopt.
