As a student, you can keep fit while studying.

Your condition is mainly fat around your waist. If you are tired of studying, you can stand up, put your hands on your hips and do a waist-closing action with your head back. Do your best, not exaggerating.

Doing so can not only stretch the waist muscles, but also improve memory. Don't believe that you can improve your memory? Try to know

Also, I suggest you do sit-ups before going to bed.

In addition, please allow me to say a few more words. It's just a matter of fat waist now, but you should take precautions before it happens. It is necessary to do more exercise, but you said you were busy with your homework, so physical education class should always take it seriously. Playing more with classmates can help you lose weight and get in shape. I didn't lie to you, because you are not fat at all. As long as you pay attention at ordinary times, you will be fine. Don't be busy studying after dinner. Standing and chatting with classmates helps digestion.
