Space Gym
Physical fitness is an important part of being an astronaut. / Astronauts must be healthy enough to perform tasks while in space, / such as taking a space walk to repair an external piece of equipment. / In space, muscles, including the heart, can lose strength and endurance / as they don’t have to interact with gravity. / Astronauts use athletic equipment modified for this special environment to maintain their physical fitness. / For example, a special running machine is used to increase their endurance, / so they can work for longer periods of time without getting tired. / They also pull against vacuum cylinders, / which lack air, to create resistance and work their muscles. /
