What do you think of those who insist on running every day in the learning playground?

A friend of mine is about 1.65 meters tall and weighs nearly 140 pounds. He always felt fat. Then the working hours are very busy.

Always can't find time to exercise. Of course, there are also many exercises that have been introduced to him. One of his colleagues bought a toy for the child, saying it was a way to exercise.

It's not about putting it on your feet and neck and playing with your feet. In the beginning, my friend thought it was a lot of fun. After a few minutes of exercising, my body starts to sweat.

I don't have time to exercise on weekdays, but I only have time on weekends. One Sunday morning, this friend of mine went to exercise again and did 300 workouts in 20 minutes. This workout made him sweat profusely.

Later, when I went home, I didn't feel anything at the time, but my leg started to hurt at night. The next day my knee started to hurt. The next night, my leg hurt and I couldn't walk.

I went to the hospital for an examination and found out that it was a muscle strain...For many days he couldn't walk or go to work.

It's that you are no longer lazy and procrastinating, it is not easy for me to run five kilometers, I have to get up early every day, and I have to leave time for myself to eat breakfast. When I got up late that day, I had to give up the exercise plan and go to school instead. But in order to exercise and run, even in the third year of high school, I insisted on running every day, and as for the heavy schoolwork, I could only improve my efficiency and plan my time reasonably to avoid wasting time.

In the end, I became a self-disciplined, plan-making, and analytical person.

If you can keep running every day, keep doing it, and never give up, you're going to get better because it can affect every aspect of your life! It can affect your body, it can affect your appearance, it can affect your temperament, your spirit, it can affect your execution, efficiency, the impact of running on us is really all aspects, these are all good influences!

Ran away insomnia, before I had serious insomnia, even a week can not sleep in the case, after running for a period of time, insomnia was completely solved, weight loss, although not a lot, but the figure has changed significantly, clothes and pants are a size smaller, cervical spondylosis has been relieved, I have severe cervical pain, a slight cold on the headache unbearable, now the number of cervical pain is less, the physical condition is much better, not easy to get tired, less cold, even pharyngitis is rarely sick.

Running is indeed a very good way to get fit. If you want to be healthy, you can only exercise more. If a person can run five kilometers a day, then long-term perseverance will have a very qualitative change in their body.

But some people are good for running, and some people are not suitable for running. How exactly should I exercise? It should be determined according to your own constitution.

Become more tenacious, and the physical and mental endurance is greatly improved. Even in the tense period of the third year of high school, I ran as usual, and my mentality has always been very good, and I didn't have a bad tone in April, so I continued to move forward steadily according to the review progress, and I didn't panic in the college entrance examination, and it was best to exceed the usual score of fifty or sixty points.

It's that your body will be stronger, but I am only 90 pounds in junior high school 170, a thin dead house, and I often catch colds. By insisting on running, I caught a cold once in three years of high school, mainly a large-scale infection. The weight has also risen from 90 to 120, running is an exercise to exercise the whole body, and the muscles have come out, and the body is better.

Overall Analysis:

If a person has a constant velocity, then the resultant force of the person is 0

That is to say, the friction experienced by the person is 0

Then the friction of the treadmill is also 0

Not too much. Details: People do push backwards, but the front feet also push forward.

These two processes do positive and negative work respectively, and the combined work is 0

Note: The treadmill rotates by itself, not because of human pedaling.

Also, don't look at the treadmill as a whole.

Decisiveness is not static friction... The friction of your contact with the ground makes you run... The force is mutual. And there are some deformations that you can't see with the naked eye. The playground is definitely deformed.
