Any human who spends enough time in a low-gravity environment — such as a future habitat on the moon — will experience bodily changes as their muscles atrophy, their bones lose mass and their control over their whole body itself declines. This is why astronauts who spend time beyond Earth's atmosphere must exercise on their missions. Without physical fitness, they’ll struggle to function on even a basic level when they return to Earth’s gravity.
Now, researchers from the University of Milan have devised a new form of exercise to keep future moon-dwellers' bodies in shape. It involves running along the inside of a Wheel of Death.
