Teaching overview

Learning points

  • Astronauts have to exercise for two hours a day to counter the effects of weightlessness on their bones and muscles.
  • The ISS has three pieces of specially adapted gym equipment: an exercise bike, a treadmill and a machine that simulates weightlifting.
  • This equipment is designed to make up for the lack of gravity on the ISS. For example, the treadmill has a harness that pulls the astronaut towards it.
