Got you. So we would need to do the experiment to try resistance training in low/no gravity to see whether it would work or not. It would seem like the obvious

  Oh, it's definitely something we should try. We need a lot more experiments. The only thing we know for sure is that moving around in 1g is generally enough for our bodies. Especially once you throw in a bit of deliberate exercise. We also already know from our space stations that 0g is bad for you, and even exercise can only mitigate some of the damage. But that's already the limit of our definite knowledge. But we don't know where the boundaries are, and whether the transition is smooth. Eg I would suspect 0.01g to be still pretty bad, and 0.99g to be indistinguishable from earth for our bodies. But would 0.9g be enough? Probably yes, but who knows? What about 0.5g? Is it bad? Is it 50% as bad as 0g? Would 0.2g give you 80% of the benefits of 1g? We don't know.

    Possibly dumb question, but if you wore weighted vests (for example) to match the same force due to gravity on earth for that individual, would that be equivalent to existing on earth without the vest? Ignoring e.g. the difference in exact distribution of the weight.

      There are some differences, eg how your organs sit inside your body. Perhaps your liver works best in 1g? We can make some educated guesses, but honestly we don't know! No one has run experiments.
