> To maintain that in reduced gravity would mean a lot of hours per day in resistance exercise. There's zero evidence for this at all. We have no experimental data on living in partial gravity, only microgravity(zero-G). It may be perfectly fine, it may be just as bad as no gravity, we truly don't know. There was a module for the ISS that was designed to test this but it got scrapped, a massive waste IMO, as it seems to be one of the most outstanding questions we have right now for space biology. Other big issues like radiation exposure is well understood.
