Do you smoke? If you smoke, it means that your lung capacity is not high, so you can smoke less, and it will be effective after a long time; If you don't smoke, are you overweight? If so, your fitness needs a long process, so you should stick to it. I live in Qingdao University of Technology. I get up at six every day, run five thousand meters on the playground, and then play basketball for a while. Lazy occasionally, run less laps. I uploaded a photo of me. (some narcissism, er ~ ~ ~) Heaven rewards diligence! Persistence will have results. Unfortunately, I can only upload one photo, otherwise I really want to show you my fitness results! Hehe ~ ~ ~ ~ insist on, uh ~ ~ ~

Dude, my friend on the fourth floor was right about breathing. You can experience it. About your figure ~ ~ ~ ~1.7 meters tall, 55 kilograms, very standard. I suggest you do more aerobic exercise. Still the same sentence: Heaven rewards diligence! Insist on の
