Anyone with a little training experience knows that the process of bodybuilding training is not the process of muscle growth, but the real muscle growth is after training. After training, the muscle fibers in the training area were slightly damaged, and after repair, the muscle fibers became thicker and the muscle mass increased. Repair needs certain material guarantee, otherwise muscles will not grow, but will decrease. Therefore, to practice bodybuilding, we should not only know how to practice, but also know what to eat and how to eat. The main substance of muscle fiber repair is protein, so it is very important to ensure a certain amount of protein intake after training. The source of protein should choose foods with high protein content, good quality and high biological value, such as eggs, meat, milk and fish. With the consumption of processed bean products, the biological price can be increased and the cost can be saved. ?
