Winter training can be improved because it is cold in winter and few people can keep exercising. If you can persist, think about the gap. More importantly, the weather itself can exercise people. I think running in winter can freeze nosebleeds. Only by running to warm up can you not run hard. Stimulate the desire to run. From putting on a coat to sweating, just warming up requires a lot of training. It is much more difficult to train before the ligament is pulled out.
In summer, you warm up in advance when you run 400-800 meters. In winter, 1500 meters feels that the warm-up is not enough, and the training level will go up. There is also a cold day to stop and rest for 2 minutes. Your body is getting cold. Can I have a rest? Running can warm your body.
I really like and am afraid of winter training. Generally speaking, winter training will be improved, of course, laziness is not counted.
I hope I can get extra points!
