Fitness will give up halfway, because fitness is spontaneous, not passive, and only people with strong self-discipline can stick to it.

Fitness is also tiring. Some people are lazy, so they are full of blood After a period of fitness, they slacked off and gave up.

Just like those fat people, you can't persist without perseverance.

Therefore, being a person with perseverance and self-discipline will succeed no matter what you do.
