A good choice for the weight gain program is simple muscle exercise plus running, but don't do strenuous exercise. You can exercise several times a day. After exercise, it is best to ensure that you eat milk and eggs every day. In addition, it is best to eat lightly. If the stomach is not good, regular muscle exercise will enhance physical fitness, drink more hot water and drink milk when it is hot. Adequate sleep is very important. Another good way to gain weight is to eat KFC once a week. Although it won't hurt to go to fast food once a week. Fast food makes people fat more easily. I hope you are in good health.
