Freefall: Losing Muscle Mass
http://freefall.purrsia.com/ff3700/fc03628.htm

I figure that the space ship to Mars must have some sort of gravity
mechanism. Of course, the best gravity mechanism on a space ship is to
fire the motors all the way there. That takes the six to nine month
trip to Mars and cuts it severely. A one gravity boost all the way
there could be as short as just a week of travel depending on the
current placement of Earth and Mars.

You "figure", do you? To date, I've seen no evidence of it.

Just don't forget to turn 180 degrees halfway and spend the rest
of the trip decelerating.

Only if you want to get there with zero relative velocity. And
depending on the relative positions in their respective orbits, halfway
may not be the correct place to flip your space ship.

r sit corrected. Approximately halfway, in order to arrive at your
destination at proper course and speed.

AFAIK, the astronaut training regimen has improved to the point
where German astronaut Alexander Gerst actually gained muscle mass
while on the ISS, in the absence of artifical gravity.

Altenating scientific experiments with workouts, I suppose.

Yes, although there is also an experimental component to
staying fit in space.

I was going to say "perhaps, being German, he actually /did his duty/
and /followed orders/", but I suppose that's a bit ... stereotyped.

*sigh*
