Without daily exercise on the Space Station, 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!".
