Treadmills Were Once Used for Torture 😨

The first treadmills weren't for fitness. They were for punishment. Prisoners walked for hours, turning a giant wheel that ground corn or pumped water. It was endless, 10 hours a day, just to exhaust the inmates. Some even died from the effort. By the late 1800s, people realized it was too brutal, and the treadmill was banned from British prisons. But in the 1960s, it reappeared as exercise equipment.
