Because we all want to change our body into a certain shape when we are exercising, that is to say, we go to exercise for our body, not for fitness, which can also explain why many people choose to give up when fitness has just achieved results. I don't think it's cost-effective, because since you decided to go to the gym at the beginning, you should stick to it instead of giving up just after you have achieved some results, so you might as well not go to the gym at the beginning, so you don't have to spend money.

If you don't plan to exercise in the middle of fitness, it is simply irresponsible to yourself. Have you ever seen a person with half a face without plastic surgery, or have you ever seen someone with half a face without money? The same is true for fitness. Either stick to it all the time or don't choose to go to the gym, so as not to waste time and money. At that time, you might as well eat something delicious. If you ask me, these people still have no perseverance and pretend to be big-tailed wolves. Finally, they chose to give up.

Moreover, many people are in good shape, but they are not satisfied with their bodies, so they choose fitness to meet their own requirements, and after reaching the standards, they put the matter of fitness down, or some people just take fitness as a pleasure, play casually for two days, and then lose interest. It is also a common problem for many people to simply give up fitness after a period of time, which leads many people to give up halfway.

Therefore, if you choose fitness, you must stick to it all the time, otherwise don't waste your time on fitness, which will have no effect at all and bring us a lot of trouble.
