First, I have gained weight.
In junior high school and senior high school, we can easily complete all kinds of sports, because the students in junior high school and senior high school are relatively light in weight and height, so that we will not be so burdened when completing the physical examination project, and naturally we can easily complete it, and naturally there is no problem in doing more than a dozen pull-ups.
In college, many people don't want to run and jump often in junior and senior high schools. They prefer to study in dormitories or schools and seldom exercise themselves. Moreover, college students are basically adults, and many students have gained a lot of weight from high school to college, which naturally makes us feel that pull-ups that can be easily completed in the past will become very difficult and difficult after the exercise.
Second, the physical quality is getting worse and worse.
Puberty can be said to be the peak of our human development. At that time, although our height and weight were still immature, we would run around and finish all kinds of interesting projects because of our energy. In the long run, our health will naturally improve.
In college, many college students often stay up late to play mobile phones and games at night, and naturally feel weak and sleepy during the day, not to mention that college students rarely go out to exercise. Even running is not as high as junior high school or high school. More students still run a few laps to keep fit. Naturally, it is foreseeable that their physical fitness will decrease. Pull-ups need to be done with all your strength. Most people are in a poor mental state. How can they have the energy to complete such a difficult action?
Third, physical measurement is difficult.
Many college students' physical fitness is still very good, but it is impossible to say that even five pull-ups can't be completed. Most college students who can't complete the pull-ups are actually more because the pull-ups in physical examination need to be completed with standard movements in order to score smoothly. The standard action needs forehand grip, and it is very difficult to use only hand strength and back muscles.
Most students like the backhand grip of pull-ups, which is not only easy to exert strength, but also can help to exert strength by shaking legs. Naturally, they can easily complete more than a dozen records, which is not allowed in the physical fitness test. Just standard movements make most students fail, not to mention many students with poor physical fitness, and naturally there will be a saying that they can't finish five pull-ups. Therefore, some netizens said: Those who can achieve five are all ruthless people!
