The Smooth 5.25 (est $1000) is a standout in its price range. The display panel is highly readable, and it folds up to save space. The Smooth treadmill has six programs and a heart-rate monitor on the handgrip. At 52" x 20", the Smooth's belt is shorter than those on more expensive models, and it has a comparatively low 275-pound capacity. However, this treadmill is backed by a lifetime warranty on the frame and motor, and five years on all other parts, with one-year in-home labor coverage.
