Space doesn’t just challenge the mind, it quietly reshapes the body. In the absence of gravity, muscles begin to shrink, bones lose density, and even the heart works less. To counter this, astronauts follow a strict daily training routine designed to keep them strong and functional while in orbit.

Because the body deteriorates quickly in space, astronauts dedicate about two hours each day to exercise. Beyond space missions, the technology behind these machines is influencing how we approach rehabilitation and aging on Earth, showing that the solutions designed for orbit can have lasting impact far beyond it.
