If you want to be a coach, you must study for at least two months, such as planing, stretching, equipment training, gadgets, functional training and basic sales rehabilitation. It will take at least two months. Some colleges can only exercise for a month at most, and some even can't exercise well. So how do they go out to be coaches? So they should study for at least two months. If you want to have a long-term development in the fitness industry, you have to take courses for three months or even four or five months, because if you want to have development potential, you have to study systematically and comprehensively, such as private training courses, rehabilitation courses, yoga, pilates, sales, management, group gymnastics, fighting and dancing. Only in this way can we have a longer-term development, and we can enter the management in the future, or we can open our own gym and fitness studio.

This is my suggestion and I forgot to adopt it.
