This is the low-profile elliptical trainer that fits under a desk and provides the same lower body motion as a full-sized machine. Ideal for multi-tasking while working out, the trainer’s non-slip pedals provide stable footing during both forward and backward elliptical movement, keeping hands free for performing office tasks or engaging in at home activities. It features eight different levels of tension enabling one to modify his or her exercise routine from a leisurely pace of low-resistance to an intense marathon of leg pumping action. The trainer connects via Bluetooth to an iPhone (5 and up, including 8 and X) or Android (4.4 and up) and uses a free app to monitor number of strides, distance, exercise time, and calories burned. A six-hour charge of its Lithium-Ion battery using the included micro-USB cable or included AC adapter provides three months of power for the Bluetooth connection. Includes two chair wheel stoppers that keep a desk chair secure when exercising. Assembly required. Black or Silver. 23 1/4" L x 17 1/2" W x 9 3/4" D. (27 1/2 lbs.)
