According to your data, I find that your weight is small, so you should gain muscle. Eating three points full and seven points full is very important for fitness. Breakfast can be eggs and milk, eat more protein such as beef, and don't eat high-calorie and high-fat foods, such as fried foods and cream cakes. As for sports, we should follow several groups of high weight and low frequency to increase our latitude. Specific training methods and pictures can be found online, and you can practice 1-2 every day. Every part needs to rest for 48 hours, otherwise the muscles will not grow. I'll make a weekly training plan for you, including chest three heads on Monday, back two heads on Tuesday, shoulders on Wednesday and legs on Thursday. The specific rest can be arranged according to your own situation, and the training time must be above 1 hour, otherwise the previous efforts will be in vain. I hope my suggestion can help you!
