Use an elliptical trainer in order to simulate jogging, without the impact on your knees! Elliptical cross training, at its best, gives you a great workout with little impact. Unlike running or cycling, you'll feel your workout in your glutes, quads and calves rather than your knees, hips and feet, because elliptical cross training offers a cardio-efficient, non-impact motion that also involves upper body movement. Treadmills are built to provide a fluid, natural motion and a superior cardio workout in the comfort and convenience of your own home.
