Solving Space: Space Bike

This summer, we are exploring how we push human extremes in order to survive and thrive in the harsh environments of space. Exercise can be extreme on Earth, but astronauts take it to the next level in zero gravity.

Cycling in space? It’s an important part of an astronaut’s exercise routine.

Onboard the International Space Station (ISS), crew members use a stationary bike to keep fit during their long duration spaceflight missions, much like people do on the ground.

The Cycle Ergometer with Vibration Isolation System (CEVIS) on the ISS offers astronauts a low-impact, high cardio workout that serves to condition their muscles and mitigate bone loss while also keeping their heart healthy. The vibration isolation system serves to lessen the impact of exercise activities on station structures.

To use the CEVIS, astronauts simply stick their feet to the pedals and strap in with the seatbelt. Then, they can get cycling in zero gravity! With CEVIS, crew members can alter the resistance and speed to maximize their individual workout profile.

Watch NASA astronaut Doug Wheelock demonstrate how astronauts workout in the weightless environment of space using the CEVIS in the NASA clip below.
