The first is their own physical problems. As we all know, people with good physique and people with poor physique have different fitness purposes. People with good physique, the purpose of their fitness is to further exercise themselves, so as to achieve a purpose of enhancing strength or shaping a perfect body shape;
However, people with poor physique are different. When they exercise, the amount is often less. If the power is too great, they will not be able to bear it. So they usually do some relatively easy training, the purpose is to keep fit and exercise. Therefore, these two kinds of people insist on fitness for decades, and the results are quite different, which is beyond reproach.
Secondly, it is everyone's perseverance. As we all know, the most important thing in fitness is not the method, but perseverance and patience. Of course, it is not that the method is not important. It is only in this Internet age that we can easily find a way, but it is not easy to have amazing perseverance and patience.
Although the Internet age has brought convenience to people, on the other hand, it has also created people's laziness, which is also an unquestionable aspect. So under so many temptations, fitness tests a person's perseverance. And this perseverance is exactly what others can't insist on. You can also think about it, if it is you, can you really keep fit for 60 years? Unless you are a person who loves fitness and is very self-disciplined, it is difficult for ordinary people to do it.
Finally, I reiterate my position that fitness can indeed create miracles, but only if you have the advantage of creating miracles and have the endurance and perseverance to create miracles.
