Elliptical trainers provide an effective cardiovascular workout that combines upper and lower body flexibility and coordination into one impact-free motion. By emulating the natural motion of your foot while supporting your heel throughout the stride, elliptical trainers are much easier on your knees and joints. In addition to feeling more natural while working out, regular use on ellipticals will increase heart and lung capacity while improving your health and burning calories. The Schwinn 431 accommodates a wide variety of users, with a full-sized 18-inch stride length and bi-directional pedaling action that lets the user pedal forward or backward depending on the targeted muscle groups. Users will also appreciate the variety of workout programs, including three heart-rate controlled programs, a calorie goal program, a time trial, a fitness test, 10 profile programs, two custom programs, and a manual option. And thanks to the Eddy Current magnetic brake resistance system, the Schwinn 431 is smooth and quiet. Other details include an backlit LCD display with such feedback programs as Recovery Mode, Results Mode, and BMI; hand-grip heart rate monitors; a water bottle holder; and bottom wheels for easy transport. The Schwinn 431 measures 59 by 26 by 68 inches (L x W x H), weighs 165 pounds, and carries the following warranties: 15 years on the frame, two years on the parts, one year on the electronics, and 3 months on the labor. A blue backlit LCD display allows you to track your progress with feedback programs such as Recovery Mode, Results Mode, and BMI. A built-in cup holder helps you stay well hydrated while exercising.
