1, long-sleeved shirt and trousers (outdoor), if it is outdoor, it is best to wear long-sleeved shirt and trousers, and don't take off your clothes, because the capillaries are wide while exercising. If you take off your clothes, the arteries and veins will close when it is cold, which is easy to cause a cold;

2, shorts vest (indoor), if you are exercising indoors, you can choose to wear shorts vest, because the indoor temperature of the gym is relatively high, it is easy to sweat if you wear too many clothes, and it is easy to catch a cold if you don't wipe your sweat in time;

3, cotton sweat-absorbent T-shirt or vest, if it is fitness running, you should wear pure cotton. If you are practicing yoga, you'd better wear a sweat-absorbent and elastic T-shirt or vest. Take a coat with you and put it on in time after yoga to prevent catching a cold.
