Many people find it difficult to visit a gym for their daily workout sessions and hence prefer to work out at home. This is the reason they use treadmills, as it is an easy and fast way to get in the daily exercise. However, a treadmill also requires regular maintenance. The machine will have a longer life only if you take care of it on a regular basis. The maintenance is not very expensive and you can do it on your own. However, replacing the parts when they wear out is necessary.
