This kind is usually seen in the gym and is usually worn by women. Another important reason is the good effect of keeping warm and absorbing sweat. If you sweat after exercise, the sweat won't stick to your body, which makes you very uncomfortable. Moreover, after exercise, the human body consumes a lot of energy and is prone to catching a cold. If you wear tight pants to exercise, there is generally no such problem.
Let's talk about sports shorts. Shorts are generally not rare, and because they are loose and breathable, they are naturally dried by human sweat. If you do a lot of exercise, your pants will easily stick to your legs, which is very uncomfortable. If you don't change clothes in time, you will catch a cold easily. I used to like fun run, and this happened.
Once I ran for a long time, and my body was basically wet with sweat, and I was wearing shorts. As a result, I didn't go home to take a shower and change clothes in time after running, and I stayed outside, without a towel and sweat. As a result, it happened to be cold that day, and I caught a cold the next day, so I dare not do it now, but a boy feels good in tight fitness pants, and it is easy to enjoy others when he goes out to exercise.
