Well, your 170cm 57kg is not heavy, and it will be blown by the wind in the park ~ ~ Brother 173cm. Now 67kg for work reasons, except for commuting for 40 minutes and getting off from the third floor every day, there is no time for exercise at other times.

Like fat, you often turn kinetic energy into muscle. If you rest 1, you will rebound in two months ~ ~ ~ If you want to exercise, you can do 50 push-ups or sit-ups every day, or both. Two groups of 50 people crouched against the wall, and their left and right hands started with 40 5 kg dumbbells respectively. Your muscles may ache for the first time. If you get used to it, you should add 10 dumbbells every day. Do some aerobic exercise, basketball, variable speed running and leg lifting when you are free. Stick to it, fat is gone, muscle is out, figure is gray, handsome ~ ~ ~ I tried it with a buddy in the dormitory in college. Although I lost, it was very effective. That's right. The stomach is not like a whole abdominal muscle now. . . . . .

Good health is king, and everything else is just a cloud.
