Hello, I am Thomas Pesquet, astronaut with the European Space Agency. On a six-month mission on board the International Space Station. In space we float all day. There are lots of muscles that we do not use. Specifically, the back and leg muscles. We have to do two hours of sport every day. to counter muscle and bone loss. Today I will show you our exercise facilities in space. On the station there are various ways to do sport. This machine is called CEVIS. It is quite simply the 'space' version of a stationary bike. It has a vibration isolation system so that your movements and efforts during exercise do not affect the Space Station itself, or disrupt the experiments in microgravity. And now, we're ready to go! The other machine that we use daily on the Station is our treadmill, called T2. It is actually a very simple treadmill. But for us to be able to use it here, it is a little bit different. This machine too is isolated from the Station walls due to the vibrations and is connected to computers that allow us to track our performance and send the collected data directly to Earth to be used there. Each of us has a personalised harness because we obviously need a force that pulls us towards the surface of the treadmill. Which happens with these elastic buckles. And now, off I go on my daily run On board the International Space Station. Finally, the last machine on the Station, the one we prefer. It is called ARED, it's a monster, with its two pneumatic cylinders, it can create up to 272 kg of force. And this is useful for us to train all the muscles of our upper body, as well as our arms, back, abdomen, and chest. But also the leg muscles when we do squats and exercises like that. One of the advantages of this machine, next to the fact that it keeps us in shape, is that from here, you've got an astonishing view just below our legs. This is the Cupola which allows us to gaze at the Earth. So it is without a doubt the gym with the best view in the world!
