First, I have been selling courses to you since I entered the gym. The purpose of most people going to the gym is to exercise and make themselves stronger, but some coaches keep moving forward to sell classes and guide the "action norms" and the benefits of personal education. The interest that led to the final fitness did not disappear.
Second, those who are responsible for your training but don't work hard or have insufficient professional quality. At present, many coaches in the gym may not have such a high level of training knowledge, but they still play a fat role and take over the business to teach, which not only leads to incorrect training for students, but also may cause physical injury. In addition, it is charged, but it is not taught by heart. The whole process only uses theoretical knowledge to prevaricate their students. When looking for a private tutor, keep your eyes open.
Third, don't focus on teaching, take the opportunity to steal money. At present, most gym coaches are men, so women often meet male coaches when they go to the gym for training, and there will inevitably be more or less physical contact. At this time, you need to pay attention to whether you have been robbed by the coach. If you hear some harassment, ambiguous words or some radical actions, then you can basically consider changing your personal education, or even changing your gym and making a claim.
