Maintaining our bodies in good physical shape is important. Medical space research has pioneered many methods and devices for monitoring and keeping astronauts healthy and strong in the weightless environment of space.
Some of these technologies are already being used on Earth for health care and many other space technologies are also finding uses in the fitness domain. For instance, solutions based on space technologies are helping the disabled to participate in sports at competitive levels and assisting them to enjoy a better quality of life. An exercise machine for astronauts is being developed into a portable home fitness device and if your skis seem better then it is probably because of space technology.
