Medical majors should maintain basic physical fitness according to the requirements of the country, so we conduct physical fitness tests every year, and this physical fitness test includes the pull-ups that boys hate most. I watched the boys in our class do so many pull-ups, and only one boy qualified. Pull-ups are really difficult for some overweight boys and some boys with no muscles in their arms, so some boys try to force themselves to do a few pull-ups in order to meet the exam. In fact, this process is a great burden on the body. Your muscles are forced to exercise, especially the muscles in your neck, which are extremely tight, and then you will pull the big blood vessels in this neck and the nerves in that neck. In fact, it is also a kind of damage to the organs inside, and the large blood vessels in the neck are very important. If they have problems because of impaired blood supply, we will also have various symptoms, for example, some people will have headaches and may also have dizziness and other symptoms.
In short, doing exercise is a good thing, but if you don't evaluate your physical fitness and do some exercise beyond your physical fitness, you will do bad things with good intentions. So, if you can't stand this amount of exercise, you can stop and have a rest when you feel bad, and then continue. The most important thing is that you can keep exercising every day, so you can do it several times in a row when your body can bear it.
