Get a total body workout at home with this Body Trac glider. The ball-bearing roller system and adjustable hydraulic cylinder resistance arms mimic the smooth motion of rowing on the water--an efficient, low-impact workout that utilizes all major muscle groups, including the back, legs, arms, abs, and buttocks. A fitness monitor tracks workout time, strokes during workout, total strokes on the machine, and calories burned to help keep you on track. In scan mode, the monitor rotates from one function to the next, displaying each for six seconds. From Stamina Products.
