This new model is very novel. You can join the gym for free. As long as you come to the gym at the agreed frequency, the fee is free. However, as long as you don't come on time once, you have to pay. On the premise of persuading people to keep fit, they also pay attention to making money, and those who earn are people who don't keep their promises.

It can be said that as long as "human nature" is always greedy and cheap and easy to be lazy, then it will make money. Humans always trust their own determination too much, and this new model makes you pay for this hasty determination, and can also say to you by the way, "It's all for your own good."
