First of all, this is because the free course environment is poor. Free courses are generally open-air, so if the weather is bad, such as rainy and windy, it is not suitable for people to exercise. Because the manufacturing cost of this kind of stadium is relatively low, and there is no special person to manage and maintain it, the stadium is often in disrepair, and young people do not like to come to the free stadium. Secondly, the facilities of free venues are generally not as good as those of fee venues. For example, professional stadiums include tennis halls and table tennis halls, and all kinds of ball games have their own professional venues, which meet the diversity of people's sports needs and make people more relaxed and comfortable. But free gyms don't have these functions, so people don't like to go.
In the city, no one cares about this kind of free stadium, so all kinds of people come in and out freely, and the stadium is often used by some people for other purposes. Whenever night falls, such a free gym may become an activity center for the elderly, and aunts may gather here to dance square dance or take a walk. In this way, the function of the gymnasium can not be well played, but it has become a park in the city. As a result, people who really need a gym are reluctant to go to this free gym.
Finally, the location of the free gym is relatively remote. People may spend a lot of time thinking about the past, and the higher time cost will make many young people flinch. Therefore, this kind of free gym with insufficient geographical location is becoming more and more unpopular. In fact, I think the stadium should still implement the charging system. Sometimes people come to exercise or prefer to get a better experience!
