Fitness instructors are equivalent to teachers, who guide students in the process of fitness, so they will be strict with students. When the wife becomes a student of a fitness instructor, it is not easy for the fitness instructor to play the role of a coach, and it is impossible to be strict with her, so the fitness effect naturally cannot be achieved. Therefore, it is more conducive to practicing fitness effects to switch to other coaches, which is not concerned by husband and wife and has no psychological burden.
