First of all, when you first enter the gym, most gyms will enthusiastically give you a physical fitness test, whether it is a member after getting a card or a customer who experiences it for free. Items generally include fat content, vital capacity, exercise heart rate, balance ability, body flexibility and so on. However, the test result is almost certain to be "sub-health". Then you will be advised to hire a personal trainer to solve these problems. But it is not difficult to get the qualification of personal trainer. Some professional coaches are not as professional as we think. The certificates of many internationally certified coaches sound very high. In fact, they only need one week of intensive training, and they can get the certificates after the exam.
Secondly, it is not easy for you to transfer cards. When you apply for a card, you usually hold your ID card. Some people need to take photos and some need fingerprint confirmation to prevent others from using your card for fitness. So when you can't go to the gym because of work or life, if you want to transfer your card, it's in trouble. Usually tell you not to turn. Even if some can transfer your card, they will charge a lot of handling fees.
Third, health problems are worrying. Gym, a sweaty place, is the easiest place to breed bacteria. Many gyms can't disinfect fitness equipment and instruments every day. There is also a swimming pool, which also has certain problems. Therefore, when choosing a gym, be sure to polish your eyes and apply for a card after inspection to prevent regret.
