The Surprising History of the Treadmill Origin

You know that whirring machine you glare at every January 2 after a regrettable fling with holiday pies? Yes, we’re talking about the treadmill.

You may view it as an instrument of personal torment invented by sadistic gym trainers. Well, you’re not far off. It’s literally an instrument of torment invented by sadistic Victorians. That’s right: the same device you use when you are rethinking the decision to have that fifth piece of pumpkin pie created to cause criminals to rethink the error of their ways.

Ancient Roots: Treading for Power, Not Six-Pack Abs

Before the treadmill became a fitness accessory (and later a glorified coat rack), it was a power source. The Romans used human-powered treadwheels to hoist heavy loads for construction projects. Picture a hamster wheel, except the hamster is a sweaty legionnaire muttering Latin curses while trying not to fall on his face. Animals also got dragged into the fun, walking tread platforms that powered everything from mills to pumps. An entire breed of dog — the Turnspit — was developed for the purpose of powering equipment in the kitchen. Exercise? No. Exploitation? Absolutely.

The Penal Treadmill: Cruelty in the Name of Reform

Fast forward to 1818. Enter Sir William Cubitt, a British engineer who decided prisons were just too darn comfy. His solution? Strap convicts onto a giant wooden wheel and make them walk. Forever. This “treadwheel,” as it was called, wasn’t meant to tone glutes. It was meant to break spirits while pretending to instill discipline. Think StairMaster, but with more weeping.

The penal treadmill often had dozens of prisoners climbing in shifts, generating enough power to grind grain or pump water—though sometimes the effort was hilariously wasted because no one bothered to connect the wheel to anything useful. Prisoners climbed the equivalent of 5,000–14,000 vertical feet a day. That’s like hiking Mount Everest weekly, only with less oxygen and fewer Instagram likes.

The treadmill became so infamous that “treadmill” itself entered the English language as shorthand for pointless drudgery. By the late 19th century, even lawmakers admitted this was cruel and unusual punishment, so the British outlawed penal treadmills in 1898. Naturally, this did not stop humans from rebranding the same idea as “fun” a few decades later.

The Medical Makeover: From Punishment to Prescription

Enter the 20th century. Doctors realized that forcing people to walk in place might reveal something about their hearts besides how much they hated the idea. In 1952, Dr. Robert A. Bruce and Wayne Quinton built the first motorized treadmill for cardiac stress testing. Known as the Bruce Protocol, it basically asked: “How long can you keep walking uphill before your heart taps out?” This wasn’t about getting beach-ready; it was about not dropping dead in the middle of your next beach trip.

Running into Living Rooms: The Birth of Home Treadmills

In 1968, Dr. Kenneth H. Cooper wrote Aerobics, convincing people that jogging was good for them (and bad for their knees). William Staub, an engineer, thought exercise should be cheap and accessible. His PaceMaster 600 became the first affordable home treadmill. Soon treadmills were everywhere—gyms, basements, and that one aunt’s spare bedroom that smells faintly of mothballs and regret.

The treadmill evolved with flashy upgrades: incline settings to simulate hill climbs, digital readouts to remind you how little progress you’ve made, and safety keys to prevent dramatic wipeouts. By the 1980s, the treadmill was a status symbol of self-improvement—or self-loathing, depending on how many miles you managed before face-planting.

Modern Marvels: Space, Science, and Sadism

By the 21st century, treadmills had gone truly cosmic. NASA built vibration-isolated treadmills for the International Space Station so astronauts could run without shaking the entire spacecraft like a martini. Nothing says space exploration like strapping yourself to a bouncy harness and jogging so the toilet doesn’t rattle loose.

Then there are anti-gravity treadmills, which use air pressure to reduce body weight and help with rehab or elite training. Underwater treadmills? Also real. Omnidirectional treadmills? Welcome to the world of VR gaming, where you can finally run away from zombies while still safely contained in your mom’s basement.

Closing Thoughts: The Eternal Jog

From Roman cranes to Victorian torture, from medical labs to your neighborhood gym, the treadmill has always been less about where you’re going and more about the fact you’ll never actually get there. It’s the perfect metaphor for modern life: lots of effort, buckets of sweat, and the sneaking suspicion that the only real winner is the guy who invented the “Quick Start” button. Next time you step onto one, just remember: you could be climbing Mount Everest without ever leaving your basement. Congratulations?
