This compact elliptical trainer earned The Best designation from The Hammacher Schlemmer Institute because it provided the smoothest operation with minimal noise. It provides plenty of clearance for the knees under desks when the desk’s underside to the floor measures at least 25" and its rubber stopper bar keeps it from sliding while its oversized, grippy pedals provide plenty of surface area contact for most footwear. It provides eight levels of resistance using a manual tension knob, starting slow and increasing performance over time, and its display shows stride count, miles, and calories. The Best model also was the most well-built of other tested models. Can also be used while sitting in a favorite chair or sofa. With built-in handle. 23" L x 17 1/2" W x 10" H. (25 lbs.)
