Moderately increase clothing

Some people will wear more clothes because of the low temperature before running. As a result, it became hotter and hotter as I ran, and I took off while running.

If the temperature is low, you can tie a windproof thin coat around your waist and put it on and off at any time according to the temperature.

Prepare for the activity for 3-5 minutes.

Therefore, before doing formal exercise, try to raise your body temperature a little. Warm up for 3-5 minutes before running. You can do some simple stretching, stretching or walking slowly.
