I don't think too many people generally like female coaches, because female coaches may not be to most people's taste compared with male coaches. Generally, men choose male coaches to have more topics, because two people can exchange ideas about fitness with each other, and maybe they can't talk about their private affairs so openly with female coaches.
In the same situation, women's choice of female coaches is not like girlfriends. It is a teacher-student relationship and will not be so hot. Under the same circumstances, male coaches will be more interested in women. I think a handsome coach is very happy to take classes with himself, but this situation is of course limited to teaching and there can be no physical contact. My statement is also limited to the teacher-student relationship between two people.
Compared with female coaches, I think male coaches covered in muscles will be more attractive. In fact, there are very few women in the fitness coaching industry now, and there are some cases, so I think it's really normal for people not to take this profession as magic all the time, and most of them are boys as coaches.
To sum up, I think if I have to choose a male coach or a female coach, I will definitely choose a male coach, not that the female coach is not good, but that the male coach is more to my taste.
