Did You Know?
Astronauts on the International Space Station exercise roughly two hours a day, six days a week, including treadmill sessions where they're strapped in with a harness, since without gravity there's nothing pulling their feet back down after each step.
Even with all that scheduled treadmill time, astronauts still lose bone density in space. The impact forces from walking in microgravity are measurably lower than walking on Earth, which seems to be part of why exercise alone doesn't fully offset the loss.
