Home treadmills are very popular fitness machines that have improved dramatically over the last 20 years. They come in a wide variety of shapes, sizes, and price ranges, so most people can find a suitable home treadmill regardless of their budget.

The history of treadmills, though, goes back farther than you might think. Would you believe that the first treadmills appeared in 1875? It's true, and they have been evolving and changing ever since.

The Beginnings of Home Treadmills

The first "home" treadmills were invented for use by animals, not people. They came about as farmers found themselves needing agricultural equipment that was portable enough to be used in different locations around their land and powerful enough to perform the job for which they were intended.

The solution was a machine powered by the motion of an animal walking. Treadmills were constructed for many different purposes and in many different sizes, depending on the animal that was going to provide the power. For example, there were butter churners that functioned with a sheep (or even a dog)providing the power via a treadmill. Other larger machines included threshing machines used in the fields and powered by horses or mules.

So how did treadmills get from the farm to the family room? The first inklings of this transformation occurred in 1952 when a doctor at the University of Washington, located in Seattle, invented a treadmill that could be used for medical purposes. Specifically, the medical treadmill was used to test patients for heart and lung disease, and evaluate the severity of their conditions.

In the 1960's the fitness equipment industry began to blossom, and home treadmills were among the first machines developed and promoted by several manufacturers. Each promoted themselves as having the best treadmill on the market, but the reality was that each different machine inevitably had its own strengths and weaknesses. Some of the earliest manufacturers included Finland's Tunturi as well as Aerobics, Inc. in the United States. Interestingly, the National Aeronautics and Space Administration (NASA) contributed a great deal to the technology and mechanics of treadmills because they saw treadmills as an excellent way for astronauts to stay fit while in space for extended periods of time. NASA developed several versions that were used aboard the orbiting Skylab station in the 1970's.
