When you exercise, do you use a treadmill? Have you thought about purchasing one? I have. Right for me its cost prohibitive. However, I do think that the folks over at Treadmills Guru have the right idea. There are so many makes and models of treadmills. There are so many different types of treadmills. One really needs a good guide to purchasing the best one both economically and physically. Treadmills Guru gives several good examples of price and a level of fitness that you want to accomplish. They also give you help with the accessories for treadmills as well.
So if a treadmill is what you are interested in, give the Treadmill Guru a look see before you purchase one.
