What's an Elliptical Trainer?

The elliptical trainer is a relatively new piece of aerobic exercise equipment, but it's here to stay. Most commercial gyms have them and they get a lot of use. An elliptical is also a great piece of home fitness equipment. Something of a cross between a bike and a treadmill, it gets its name from the elliptical, or egg-shaped, motion of the pedals. Ellipticals can be used by anybody from a deconditioned beginner to a pro athlete.
