Treadmills are the most popular of all the fitness equipment in use in the US today. The National Sporting Goods Association estimates that treadmill sales last year topped $750 million. That's big business. It is estimated that around 8% to 9% of the population own a treadmill. You do the math, but to me that's around 20 million people. That's a lot of treadmills that have been bought, and a lot of treadmills which may soon become used treadmills for sale. Refurbished treadmills are big business. Because treadmills can be so expensive there are many who can not afford to buy a new one. Although treadmills are some of the most popular items of fitness equipment in the US, they don't appeal to everyone. Some people can find that they use a treadmill for a while and decide that they prefer some other form of exercise. Sometimes it not another piece of indoor exercise equipment, it's just that they prefer to exercise outdoors. 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. Basic Components The basic components of home treadmills are important to understand and consider before you decide which brand and model to purchase. These basics are the foundation for the durability, reliability, and usability of your treadmill. Motor - The size of the treadmill's motor is important because it will affect overall performance of the machine. A motor that is too small will not provide sufficient power and will breakdown more quickly than a motor that is the correct size for the type of use your treadmill will receive. Belt - The belt should be durable and not prone to excessive wear. A two-ply or greater belt is best, because a single ply belt will simply wear out and need replacement too quickly. The belt should also be large enough to accommodate the length and width of your stride. Deck - The deck is important because it flexes when your foot strikes it, cushioning the impact and helping to prevent injuries like shin splints, back strain, and foot problems. Look for a deck that is at least ¼-inch think and provide the lowest impact possible. Display panel and controls - The display panel and controls should be easy to read and operate. Push button controls are best because they are easiest to use while you are in motion. The display should have large numbers and be able to show critical information like your speed, the incline you are using, the amount of time you have been on the treadmill, and the equivalent distance you have covered.
