National Space Biomedical Research Institute (NSBRI) scientist Benjamin D. Levine, MD, talks about the need to maintain fitness during space missions. The microgravity experienced in Earth orbit and the low gravitational fields on the Moon and Mars will have negative effects on astronauts' muscles, bones, and cardiovascular systems.

Without good stress, muscles atrophy and bones demineralize. How can astronauts maintain fitness during space missions? What are the best exercises?
