"Sometimes one has to work on one's mental fitness."
I'd like to know if it would be correct to replace "one's" with "his" or "her."
Using "his" suggests you're talking about someone else, as in the following:
"The problem with having a husband is that sometimes one has to work on his mental fitness."
If you start with "one's", you're pretty much stuck with it for the rest of the sentence.

If the respective referents of 'one' and 'his' agree in gender, number, and person, go ahead. In certain nonlinguistic contexts it is possible.
What about "Sometimes one has to work on their mental fitnesses." ?
