First, the belt should not be too tight;
Second, the material should be breathable and absorb sweat; ?
Third, flexibility is better. In terms of gender, women's underwear should be tight and appropriate. If it is loose, it will shake and affect the movement. If it is tight, it will tighten the body, increase breathing and cause discomfort. In addition, the underwear should be wider, otherwise it may cause chest tightness, shortness of breath and poor blood circulation. ?
In terms of underwear, both men and women should choose cotton products that are overall loose, breathable and sweat-absorbent. "A little looser underwear will reduce the resistance during exercise." Zhang Yimin said that it is best to choose a wider underwear belt, and the underwear model should not be too small, otherwise, if you don't let go of your hands and feet during exercise, it will oppress the reproductive organs. If the permeability and sweat absorption of underwear are not good, the heat and sweat stains generated after exercise can not be eliminated in time, which affects reproductive health, such as briefs, and it is best not to wear them during exercise.
