This is how NASA astronauts work out while in space

How does a NASA astronaut work out with no gravity?

Gravity is an incredibly important thing. Mainly, it keeps us from floating about while we're walking around, grounding us to the earth. As such, it plays an important role in how we move our body, including working out. Gravity is everything when it comes to exercising, all of our movements see us working against it, and using it, our body weight and any weights we are holding to return to our original state. So when it comes to astronauts, who need to be in peak physical condition, a workaround without gravity is needed to be able to stay in shape while outside of the Earth's gravitational pull.
