Space Station fitness

Hello, I am Thomas Pesquet,
astronaut of the European Space Agency. On a six month mission on board the
International Space Station. In space we float all day
There are a lot of muscles
that we do not use. Specifically the back and leg muscles. We are 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!
