As an alternative to strenuous exercise (which loads the water and CO2 processing systems of space stations, and makes the place smell sweaty) the Russians experimented with vibration therapy to impact-load cosmonauts' skeletons. Not sure why they have gone back to treadmills.
It's interesting to compare radiographs of policemen and soldiers. Pretty much the same sort of person, doing the same sort of job, but constant slow walking gives coppers a characteristic heavily mineralised pelvis and femur, whilst soldiers crawl, run or drive, and have rather more "normal" bone density.
