• You have to be in shape to be an astronaut! In space, astronauts’ bodies can lose strength and make them feel weak when they get back to Earth.
    Watch this video to learn how astronauts work out, and how you can exercise like an astronaut using equipment in your school, gym, or home.
    • Astronauts use a TVIS (Treadmill Vibration Isolation System) to increase their endurance, so they can work for longer periods of time without feeling weak. On Earth, we can go running or use a treadmill.
    • Astronauts use an ARED (Advanced Resistive Exercise Device) to build strong muscles. Back on Earth, we can lift weights or use weightlifting machines.
    • Astronauts ride a CVIS (Cycle-Ergometer Vibration Isolation System), an unusual stationary bicycle, to help improve their cardio (heart) health. On Earth, we can go for a bike ride or use a regular stationary bike.
