Ellipticals and Your Knees

People with bad knees love the elliptical trainer. As a non-impact machine, it spares your knees the pounding they get from running, but still gives a great workout. Many ex-runners whose knees gave out use the elliptical to get a vigorous workout. People whose knee problems come from arthritis or other conditions can get a workout, perhaps less vigorous, but equally enjoyable and beneficial.
