Elliptical cross training empowers you to feel exhilarated, rejuvenated and satisfied with every workout. Unlike running or cycling, you'll feel your workout in your glutes, quads and calves rather than your knees, hips and feet.They are low impact. In other words, even persons with problems with their hips, knees,feet, or spine can use elliptical trainers. • They offer you a chance to get a full body workout. The majority of elliptical machines do not simply work your lower body: they have handles so that you can be working out your upper body at the same time.
