Honestly... I don't think it is.
I've found that my followers like my style as much as my specific content. I've definitely got people that are only interested in the fitness stuff, and that's fine, they just won't read the other stuff I put out that doesn't interest them... I'd say maybe 70-80% of my real followers are happy with whatever topic I write about.
I honestly wouldn't stress too much about it, writing a broad range of topics might attract more visitors in the long run.
So, I've taken your advice and put a solid amount of effort into forging connections with others. It is all a work in progress but I'm getting the rhythm down! I'll gladly accept other advice if you have it. I appreciate your help.
