First of all, not everyone has such good economic conditions that they can build a gym at home. People in the middle class and below have no choice but to go to the gym for fitness, or go directly to outdoor activities such as running and playing basketball. I can do more things with money. Personally, I don't have that high requirement for fitness.
The atmosphere at the gym is better than at home. I am a weak-willed person. If I am allowed to exercise at home alone, I may not last long. When the gym is built, maybe my enthusiasm for fitness will soon fade. At most, I will spend three days fishing and two days drying nets, which can't really achieve the purpose of fitness. But exercising in the gym is different. When you want to rest, others are still sweating like rain. How can you be lazy there? It can also be used as a driving force for fitness.
Fitness in the gym can not only help us keep fit, but also let us know many like-minded friends. People who go to the gym spend money. Generally speaking, they are all people who love fitness, and there will certainly be many like-minded people. The doubts encountered in the process of fitness can also be discussed. This is also conducive to the cultivation of extroverted and communicative personality. If you are an introvert, going to the gym is really a good choice.
Fitness is a technical activity, and many fitness methods require certain skills. If you practice alone. In strength training, once the posture is deviated or the stress position is wrong, it may hurt the body. But if you practice in the gym, there will be a coach to correct your mistakes and help you make a better fitness plan. Of course, if you have money, you can also hire a personal trainer.
