Hello, my friend. I have been working out in the gym for two years. As far as I know, there are more girls taking yoga, and Latin dance is more popular. Personal education mainly depends on your personal marketing ability. With more students, you will naturally earn more. Appearance is of course important, but it is not necessarily a beauty, nor is it a beauty contest. The most important thing is good health and professional skills in this field. Besides, if you do this, you will succeed.
