The Extended Stride Elliptical/Stepper is compact without sacrificing its ability to deliver a thorough and effective workout. The moving handlebars add an upper body workout to your cardiovascular fitness program both in Elliptical Mode and Stepper Mode. In Elliptical Mode, you get a workout that is a unique blend of stair climbing, cycling, skiing, and walking all together in one movement. In forward motion, your quadriceps, buttocks, lower abdominal, hips and thighs are targeted. In reverse motion, your hamstrings, lower buttocks, hips, thighs, and calves are targeted. The Stepper Mode works the same muscle groups with a vertical motion.
