The ProForm 10.0 ZE Elliptical is the most popular ProForm elliptical that comes at a great price. Its adjustable stride lengths let you choose from 13, 15, or 18 inches so you can get different elliptical patterns and target different muscles. With an iFit card reader, you can add even more interactive workouts for a wide variety and refreshing pick every time you work out. Very few ellipticals fold up like treadmills. The ProForm 10.0 ZE Elliptical is one that does. It lets you save floor space, so if you don't have plenty of room, you can always fold it up when you're done and store it easily. In addition to the iFit workouts, you get 8 built-in workouts designed by a professional trainer to maximize calorie burning and weight loss. This elliptical automatically adjusts the resistance throughout your workout. Slip-resistant, over-sized foot pedals allow you to change into different foot positions and gives you the stability when exercising. A blue-tinted LCD window with priority display lets you track your workout progress as you exercise. A 5x7-inch workout matrix displays your workout graphically and lets you choose which readings to appear on the display so you'll have the information you want right when you want it. Heart Rate grip sensors are built right into the stationary handlebars so you can monitor whether you are within your target heart rate. An iPod dock lets you rock to your favorite tunes. Keep yourself cool and comfortable with its built-in fan while you work out.
