Chris Hadfield -- CSA Astronaut, ISS Commander and the human explainer for all things space-related -- answers another question with his latest video: how do astronauts exercise with that zero gravity and all? Turns out, they do a lot of the same stuff we do: running on a treadmill, deadlifts, squats and more.
The difference is that their exercises require being carefully tied down by a harness. Plus, astronauts have to work out two hours everyday to maintain bone and muscle mass.
In the video, you can see the T2 treadmill and the ARED (Advanced Resistive Exercise Device). But what about... sweat? [CSA YouTube]
