Hello! You want to be fatter and stronger, so I suggest you: 1, have a good sleep; 2, adjust the mentality and maintain a pleasant temperament; 3, regulate the body, pay attention to diet, and ensure gastrointestinal health. In addition, there are still some problems in your body, such as weak heart and stomach, and you can't get fat if you eat too much. Don't worry, and don't think about it. You should start with maintaining the gastrointestinal tract, pay attention to diet, and eat less spicy food and rice (if it is a girl); Then pay attention to sleep and rest to ensure the function of the heart. I wish you happiness! ! !
