In my research on treadmills, I found the SupeRun Walking Pad. This bestseller and the reasons are obvious! The price is very reasonable. It has a 2.5 horsepower engine, plenty for a walk or a run. It holds up to 300 pounds. It is portable and weighs only 40 pounds. If you are in a small space it can easily slide into a closet as it folds up. With over 2200 sales it has a 4.2 star rating. It also comes in 8 colors. Treadmills are awesome for people who can't get out and about because of the weather or aren't comfortable venturing outside.
