CSA Presents: The Hadfield Shake – Exercise on the ISS
100 Comments


Weightlessness is cool. It lets you do things you just can’t do anywhere else. You can fly and float and turn. But it doesn’t come for free. Without constant load on your body, you can get incredibly lazy. Your muscles will start dissolving. Your bones will start getting reabsorbed back into your body. So to stay strong to go out on a space walk and fight the space suit, or so you’re strong enough to walk around when you get home again, we have to exercise. We have to demand that our bodies stay strong. And we do that in various exercise equipment here on the Space Station, including T2, Treadmill Number 2, the Terminator, right here on Space Station. Time to exercise. (MUSIC) So… make sense? That’s how we exercise in space, keeping ourselves strong and fit and ready for whatever might happen. Bye.

  1. greenwich. He explains it in a vid as a compromise between ground-crontrol Houston and Japan (?) ^^ and alle these other ground controlls on earth (6 or so)

  2. It'll just pool up on the cut but since space weakens the immune system, it would take longer to clot, longer to heal and increases the chance of infection.

  3. The "Terminator" I understand. But the gigantic muscle-building machine… Wouldn´t an elastic band suffice? 🙂

  4. Chris Hadfield you are a Canadian hero. Thank you for being such an incredible overachiever. I could not think of a better role model for young people. I love all your videos but I cant help but think this one would have been better if done as a Body Break commercial. To your continued success and safety Sir.

  5. You should always be careful when tying your shoelaces in space, too loose when exercising and you might step on them and fall.

  6. He's a bad role model because he makes me want to be an astronaut even though I'm too old and stupid. 🙁 At least Niki Manaj gives me attainable goals!

  7. See the towel video, it would be just like that. The blood would gather on the cut like jelly, getting bigger and bigger.

  8. Are there any muscle groups that, despite the Agency's best efforts, you are unable to exercise? Do you find that when you come back to Earth certain parts of your body are dis-proportionally weak? Perhaps some internal stabilization muscles?

  9. It's a resistance machine: not heavy but hard to pull.
    Like pulling on a bungee cord as opposed to lifting a dumbbell.

  10. They use spring retention to provide force, against which they pull/push, simulating weightlifting. In space there may be no gravitational potential energy however there remains elastic potential energy.

  11. It is absorbed into the walls and through a purifying process it is a part of their water supply and life support

  12. (with the understanding that I'm not even REMOTELY attached to the space program)
    In other videos they talk about the water recycling system of the ISS recovering water that evaporates from towels and the like. I would presume that the exercise areas have a slightly higher than average air flow, and that the water recycling system takes the evaporated sweat, extracts impurities, and returns it to the potable water system.
    I'm GUESSING urine is probably processed the same way, but *shrug*

  13. How does the weight lifting machine work if everything is weightless! Is there like a mechanism that pushes against you?

  14. The blood will dry as normaly so the bleeding stops. And you can probaly just pick up the floating blood. My guess 🙂

  15. All of the exercise equipment provides resistance in lieu of gravity by using springs, elastic bands, or hydraulics. The treadmill you see is holding Chris down with a pair of giant rubber bands that hook onto that vest.

  16. A wonderful video, with an impeccable edition and music.
    And Chris Hadfield is the new Chuck Norris!

  17. Can someone please find out what this song is? I've looked through every comment and so far no one has got it right…..

  18. No, it is transferred trough their ventilation system and is taken to a purifier where it is turned back to water.

    Nice try at using complicated words to sound smart though.

  19. I wonder if they have ever considered adding a spinning artificial gravity section to the ISS? Or maybe to the next space station that is supposed to go up in the 20's.

  20. whats the song name?

    he uploads them through a satellite

    to become an astronaut you need to:
    know how to read and write in your spoken language
    have 20/20 vision
    know mathematics and have an engineering degree
    have past flight experience and a few other things
