In fact, fitness is a professional knowledge, and there are still many things to learn. You can buy some books on this subject. There should be a shop to buy used books in the university annex. You can buy some books such as Health and Beauty or Mr. Bodybuilder, and there are many ways to introduce sports.
I bought second-hand books at school and learned a lot about fitness. Later, I worked as a coach in the school gym for two years. But unfortunately, I didn't rely on a fitness professional qualification certificate. At present, there are many professional qualification examinations for fitness, which are investigated by fitness coaches all over the country and many professional fitness institutions. Both health and beauty and bodybuilders have this information. The research of general professional institutions is relatively simple, but the cost is relatively high, which seems to cost two or three thousand yuan. Generally, it takes ten days to half a month for training to issue certificates. If you want to do a part-time job in the future, you must take a certificate. After graduating from college, I also found a job in fitness, but I didn't apply successfully because I didn't have a professional certificate. In addition, I was still hesitant to do this major or do fitness in this bank, which also wasted many opportunities. So if you are interested in this, you should plan ahead.
Finally, good luck on your fitness journey.
