The salary of fitness instructors is still relatively high, mainly because the number of members who pay for personal fitness instructors is also increasing. If your members have no money, then no one will hire a coach. But now people's living standards are basically well-off, and people's income is still relatively high.
Second, the pressure of modern life and work is increasing, the physical quality is getting worse and worse, and sub-health is becoming more and more common.
Although people are rich now, their physical fitness is getting worse and worse. It may be because of money, on the one hand, I am lazy, on the other hand, I am more indulgent in diet. I can eat whatever I want without scruple. So now the social obesity rate is also very high. Money brings people not only face, but also illness, obesity and laziness. It is also because of these that our health is getting worse and worse. We need to go to the gym to exercise and improve our physical fitness through exercise.
