Water used for therapy should be considered?

Can the atrophy of the body be prevented by the use of swimming?
Never saw a fish out of shape yet. Perhaps an alternative system that
used high pressure air to simulate water resistance might be worth
pursuing? Obviously you are not going to put an olympic pool in space
with our limited experience, however enough water to "swim", allowing
the arms and legs to vigorously exercise might be worth considering as
a policy?

I would think a high pressure air system would be pretty noisy. The
dangers or space flight are just not worth the costs invovled?
Considering the only available destinations, I fail to see how manned
space flight can be any better than unmanned. Between radiation and
flying debree, space craft are disposable, people should not be?

The tensile load on the pressure hull would be outrageous.

Maybe some spacecraft might have a double-walled hull with 2 meters of water
in between for radiation protection. Of course you'd have to bring your
scuba gear (and rebreather if you didn't want to gradually displace your
radiation shielding).

But I offer that up semi-facetiously. In all likelihood, such a shield
would be ice rather than kept liquid.
