What is a nordic track elliptical?

A Nordic Track Elliptical is a type of cross-trainer - an exercise machine that mimics the movements of walking, jogging, or even cross-country skiing. These types of exercise machine have th benefit of reducing the stress from impact on the joints that can sometimes be experienced on more traditional treadmill-style machines, making them safer for people with hip, back and knee injuries, for example. The Nordic Track is a well-established brand, and a number of models are available through their website, ranging in price from $579 to over $1,000.
