At present, there are two kinds of domestic coach certification: Asian fitness personal trainer certification and American fitness personal trainer certification, which are recognized by large and medium-sized domestic clubs, such as China Sports Billie, Jade Bird and Baolihao, followed by national fitness trainer certification, but not as good as the former. Where to participate in training certification depends on whether there is such a training institution in your city. I don't know which city you are in. The easiest way is to find the nearest training institution through online information. Your brother works in Haosha. You can ask the coach of the club where he participated in the training through him.

As for the qualification of coaches, although the qualification examination for coaches is rather confusing in China, they still need to be certified. As I said before, in my club, I pay more attention to the practical experience of coaches. Professional knowledge is very important, but experience is more important for a personal trainer, because you need to help others better achieve their training goals, which can be done not only by professional knowledge. In addition, the coach's body shape does not necessarily require a large circumference, because the members of the fitness club we usually talk about are generally for the purpose of keeping fit, not professional bodybuilding, so circumference is not the only standard. If you are fully prepared for training, reducing fat and improving heart and lung function will be of great help to you as a personal trainer. Reading books on anatomy, sports medicine and nutrition is very helpful for you to do this industry. Of course, if you have a strong body, it will be more convincing.

Finally, I wish you success!
