I ran into an issue. My sub-niche started off at gaining muscle, then it became two sub-niches: gaining muscle and losing fat. I'm working on a domain name that fits the combination. I know its always suggested to work on one and master it first before working on another. And I know the combination is a pretty broad and competitive niche.
Is It best for me to separate the two and just work on one for now for ex. gaining muscle and just create a domain for that, then create another domain name for losing fat later?
It seems like the two end up combining all the time when I write my content and it seems like in the long run I will need one site for both which has me a bit perturbed.
Any suggestions please.
Thanks
