Why does the fitness instructor take the Muay Thai certificate?

Self-defense is the common need of all mankind, and it is of course more ideal for a fitness instructor to know Muay Thai.

Fitness is to be healthier and more temperamental. Muay Thai is a comprehensive sport, which requires not only strong physique, but also strong fighting ability. Ordinary people only practice their own bodies, but can't reach the skills of self-defense. Muay Thai is fierce and suitable for self-defense. As a fitness instructor, if you can master this skill, you can attract more customers.
