Exercise seems to have little effect on bone loss, but it does reduce muscle shrinkage and generally improves an astronaut's sense of well-being it may also be essential to a mission: astronauts can move around inside the iss with very little effort, but spacewalks - or even installing heavy equipment within the station - involve heavy work.
