You'd better not always stay in the same place to exercise. Just like the principle of exercising on a treadmill (your knees will be seriously damaged). Why does the rabbit stay in the nest all the time? This has nothing to do with wearing shoes or not.

If it is hot in summer, I can get up early. I am dragged out to climb mountains by my mother every day! ! (Fortunately, the summer vacation is coming to an end ...)

I wish you an early run of two kilometers. ...

And remember to go to the hospital. Health is the most important thing.
