First of all, your body is the capital of everything. Whether you are fat or thin, you should keep exercising, which is good for your life and study. Then let's discuss the method of exercise: you are thin, you want to grow stronger and have a better system, so you should do more muscle anaerobic exercise, and add enough protein after exercise, and you will get results if you stick to it. That is to say, exercise is on the one hand, and food is on the other hand, and their roles each account for 50%. I'll give you a simple arrangement, and you can make some adjustments according to your own situation. Do 5 groups of push-ups every day (if you feel that you can do a lot and keep your feet high, it is best to do only10 ~15); Sit-ups 100, sit-ups 60 (you can do them in groups, but don't rest too long between the two groups); Five groups of weight-bearing squats, the weight can be controlled by themselves, and it is best to do up to 20 30 in each group. If there is equipment on the playground, do five more groups of pull-ups (forehand grip), each group 15. After exercising for 20 minutes to 1 hour, use protein and carbohydrates. To put it bluntly, eat more staple food, eggs, beef and so on. I believe that you will improve greatly after you persist in this way for a period of time. If you feel that the effect is not obvious, you can go to the gym to practice with equipment, so that the progress will be more obvious. I wish you good health ~ ~ ~
