While millions of gym-goers worldwide view the treadmill as an essential cardio machine for fitness and endurance, the origins of the device are rooted in nineteenth-century prison discipline. Originally dubbed the “everlasting staircase,” the machine was conceptualized not for personal wellness, but as a deliberate mechanism of physical strain and penal servitude designed to wear down convicts serving sentences of hard labor.
The 1818 Invention of the ‘Everlasting Staircase’
The penal treadmill was engineered in 1818 by Victorian civil engineer Sir William Cubitt. Unlike the motorized flat-belt conveyors found in modern health clubs, Cubitt’s design consisted of a massive rotating cylinder fitted with external steps. The apparatus enabled multiple prisoners to tread alongside one another simultaneously, continually climbing steps that shifted downward beneath their body weight.
The daily regimen enforced upon inmates was grueling. Prisoners were frequently ordered to walk on the penal treadmills for an average of six hours each day. Under this rigid routine, convicts were granted only an average of 12 minutes of rest for every hour spent stepping on the wheel. A modern visual simulation produced by Zack D. Films illustrates the grueling nature of the contraption, showing mechanics that bear a closer resemblance to a contemporary stair-climber than a standard running track.
Ideology and the Psychological Toll of Hard Labor
Although some versions of the apparatus were connected to machinery to grind grain or pump water, others served no productive economic function at all. According to academic Vybarr Cregan-Reid, the apparatus was viewed during the Victorian era as an ideal disciplinary instrument specifically configured to exhaust inmates through relentless exertion.
Speaking to BBC Radio 4, Cregan-Reid detailed the philosophical thinking that underpinned the machine’s widespread adoption:
“They were invented to solve a problem,” he told BBC Radio 4. “It came out of the Enlightenment… this idea that punishment should be fair and appropriate, and it should teach the criminal to behave in a certain way.”

Oscar Wilde and the Abolition of the Penal Treadmill
The punishment was routinely assigned to prisoners sentenced to hard labor, including famed Irish poet and playwright Oscar Wilde. Following his conviction in 1895, Wilde was sentenced to two years of hard labor, during which he was subjected to the treadmill. As highlighted by Cregan-Reid, the severe physical and mental toll of this sentence caused irreparable damage to Wilde’s health; the writer died only a few years after his release from prison. Public support for the device gradually deteriorated, leading to the official abolition of the penal treadmill across the British prison system in 1902.
Why This Matters
The history of the treadmill highlights the shifting cultural boundaries between punitive physical discipline and voluntary health regimens. Originally engineered during the Industrial Revolution to enforce uniform, quantifiable punishment, the mechanics of forced step-climbing eventually transitioned into personal conditioning and cardiovascular science decades after its penal retirement. Understanding its history provides critical context on nineteenth-century penal reforms and the physiological strain associated with continuous step-based exercise.
Frequently Asked Questions
Who invented the original treadmill and when?
The penal treadmill was invented in 1818 by British Victorian engineer Sir William Cubitt as a method of enforcing hard labor in prisons.
How much time did Victorian prisoners spend on the treadmill each day?
Inmates were required to walk on the rotating wheel for an average of six hours per day, receiving roughly 12 minutes of rest for every hour completed.
When was the treadmill officially banned in prisons?
The penal treadmill was officially abolished as a method of prison punishment in 1902, several years after its use contributed to the declining health of inmates like author Oscar Wilde.
