#引体向上#引体向上能一次做20个是属于很高的水平了! Let's take a look at the pull-ups.
First of all, although doing pull-ups is a simple form of freehand, you also need to overcome your own body weight and do resistance movements, so the heavier the person, it will be more difficult.
Secondly, the standard posture of pull-ups is to keep the body hanging naturally, tighten the core muscles, grasp the horizontal bar with your hands shoulder-width or slightly wider, then inhale and pull the body up to the jaw over the bar, and finally slowly lower it to the original position.
Standard pull-ups are not easy for most people, they require a certain amount of skill and strength, and it is not easy to do 3~5 when you just start practicing.
Because to do more pull-ups, you need not only strong upper limbs and core muscles such as latissimus dorsi and biceps, but also good coordination and some endurance. Such people usually have a high level of fitness and perform well in fitness, sports, or other areas.
If a soldier is in the army, as the assessment standard of a soldier's physical fitness, 12 pull-ups are passing, and 16 are excellent. Therefore, it is more powerful for ordinary people to be able to do 20 standard pull-ups at a time!
However, exercise pull-ups should also pay attention to safety, it is really admirable to be able to do 20 pull-ups at a time, but everyone should exercise according to their actual situation, and the number of pursuits should be gradual to avoid muscle strain caused by excessive exercise.
