Apologies for the background noise, life on @Space_Station is loud! Without daily exercise on the ISS, we would lose significant muscle mass and bone density, since we don’t have the daily loading on our bodies that Earth’s gravitational environment provides. We have the ARED 🏋️‍♀️ (Advanced Resistive Exercise Device), an engineering marvel that can be configured into a large number of weight lifting exercises, a cycle ergometer 🚲 (think a stationary bike with no handlebars and no seat — not needed in space!), and a treadmill. 🏃‍♀️ I started exercise right away, and it was so cool. Complete muscle memory! Really feels like I never left. Here’s a peek into our daily exercise routine!

@Astro_Jessica @Space_Station No earthly workout could compare!

The ARED is genius - counterweights up to 600lbs simulate heavy squats/deadlifts in microgravity. The inertia isolation is critical too; without it, every squat would wobble the entire station. CEVIS (the bike) uses magnetic resistance instead of weights. Muscle memory really does carry over - that's the beauty of consistent training.

@Astro_Jessica @Space_Station This was unbelievably fascinating. Thank you so much for showing me this.

@Astro_Jessica @Space_Station Thankyou for sharing.. I’ve often wondered if there was equipment/ how/what/ … all the questions… amazing!! 👏🙌

@Astro_Jessica @ShuttleAlmanac @Space_Station The absolute coolest thing I’ve ever seen! Our Astronauts are bad asses!🔥👊

@Astro_Jessica @Space_Station Thanks for sharing this, stay safe up there. GOD watch over you.

@Astro_Jessica @Space_Station With the nextgen space stations can we spin them to create 1 G on the outer parts of the spinning station?

@Astro_Jessica @Space_Station Do you listen to music 🎵🎶 while you exercise?

@Astro_Jessica @whoisinspace @Space_Station Someone recently posted that some astronauts *gain* bone mass in space! Is there any correlation with exercise type and change in bone mass (controlling for ground exercise regimen)?

@Astro_Jessica @Space_Station you may not know the answer to this, but how does the weight lifting machine work to counteract anti-gravity?

@Astro_Jessica @Space_Station Do you sweat when exercising in space?

Free Cone Day is here! Come celebrate with us at a DQ location on today by getting a FREE small vanilla cone 🍦

@Astro_Jessica @Space_Station Nice space hair!

@Astro_Jessica @Space_Station Carbo load before and creatine after?

@Astro_Jessica @Space_Station Due to this need astronauts at the ISS are probably some of the most fittest humans in the entire world, only to be not ON the world.

@Astro_Jessica @Space_Station Amazing thank you ! « No seat on the bike » 😳

I'm always amazed/dumbfounded that they don't require long hair in a bun or at least ponytail, and surprised most do not make the decision themselves regardless. I would think you'd be more concerned about long hairs getting loose and clogging stuff up. It looks cool and fun, but isn't the safety of the ISS and other Astros far more important?

@Astro_Jessica @Space_Station Very cool. Inspires us on earth to get in our daily movement 👏👏💪🏃🙏

@Astro_Jessica @Space_Station That’s great info. I’ve been interested for years in how bone density loss was being addressed. Cheers!

@Astro_Jessica @Space_Station That’s really cool! Stay fit Jessica and keep up the great work!

It’s time to dance! Get it on tournament action with Bonus Bets from FanDuel.

@Astro_Jessica @Space_Station Hi Jessica! I was curious, has NASA ever tried resistive full body suits?

@Astro_Jessica @Space_Station Why not just build a Space station like a rotating wheel for artificial gravity? Like in 2001?

@Astro_Jessica @Space_Station I bet that Zero G would be perfect for my nasty backpain, right, Jess?

@Astro_Jessica @Space_Station I guess with weightlessness, you also have anti-gravity hair if it's longer as yours is. Excellent versatile exercise machine.

@Astro_Jessica @Space_Station You are, beautiful, the edge of the sword, a lioness, you can do 4 reps of 12, go for it, take it out of orbit. Less talk and more exercise. 😂👍👍💎

@Astro_Jessica @Space_Station Loved the expose. Does the machine allow atg squats?

@Astro_Jessica @Space_Station Can you see the city lights at night with the human eye? Or are those amazing photos and videos of cities on earth taken with special extra sensitive cameras?

@Astro_Jessica @NASASpaceOps @Space_Station None needed. That’s the sound of the station!

@Astro_Jessica @Space_Station I know this is pretty minor in the overall scheme of things but I think it would be so cool to have your hair drifting around all the time. I have long hair so I’m imagining what it would feel like for it just to float.

@Astro_Jessica @Space_Station If space has limited or no gravity, what benefit is gained by lifting 'weights' in a zero gravity environment? Who authorised lifting weights to this altitude? What is the cost benefit analysis on this?

@Astro_Jessica @Space_Station Also, because the physics of every action has equal and opposite reaction, these exercise devices have to be inertia isolated from the body of the ISS or their movements would be imparted on every part of the ISS all the way to the end of the solar panels, making them wobble.

@Astro_Jessica @Space_Station amazed at the cramped quarters and supplies stored everywhere. i always imagine disgusting smells too. i could never do this.

@Astro_Jessica @Space_Station Thanks for sharing this! 🙌🏼💪🏽🙏🏼

@Astro_Jessica @Space_Station Okay heart me out. Doing the squats, but another astronaut behind you is watching like gym videos go. But then it turns out they're looking at something real nerdy

@Astro_Jessica @Space_Station @grok does that lack of gravity affect internal organs, blood circulation, etc.?

@Astro_Jessica @Space_Station I recently saw the ISS mockup of this at the US Space and Rocket Center in Huntsville, Alabama! Now, I feel like I can almost relate 🌎

@Astro_Jessica @Space_Station What’s your PR for squats on that machine?
