First, put an end to snacks. This is the most important point. It's easier said than done. You should have self-control. I think the food in your school may not be very good, so we usually use snacks instead of meals. If you must eat snacks, I suggest you prepare more sugar-free jellies and fruits and vegetables, such as cucumbers and carrots.
Second, seize every possible exercise opportunity. If your school has morning running, physical education class and activity classes, don't be lazy. But remember, anaerobic exercise is not to lose weight, such as 100 meter sprint, weight lifting and so on. Aerobic exercise is to lose weight, such as jogging and walking. Personally, I suggest walking. When walking, you can not only exercise, but also sum up your day's life and meditate. I also have my own original method, that is, don't do homework immediately after dinner. I will gallop on horseback for about 15 minutes, which has a good effect on obesity in the lower body. Also, when you are on duty, you should sweep the floor and mop the floor more. Don't take the bus. You can grab the handrail and practice on tiptoe to help shape the perfect calf curve.
Third, mentality. Losing weight is a happy thing. If you just want to attract others' attention to lose weight with a good figure, you are likely to lose weight unsuccessfully. You must think about it: losing weight can give me a healthy body. Losing weight is for my own good. I will work hard and get good grades in the joint physical education exam. Only in this way can you succeed.
Finally, I wish you success in losing weight! Come on, mid-term exam! You can also chat with me online, welcome!
