An elliptical trainer (also cross trainer or simply elliptical) is a stationary exercise machine used to simulate walking or running without causing excessive pressure to the joints, hence decreasing the risk of impact injuries.

Elliptical trainers offer a non-impact cardiovascular workout that can vary from light to high intensity based on the resistance preference set by the user.

An elliptical trainer is designed to provide a cardiovascular workout rather than build muscles. Though elliptical trainers are considered to be minimal-impact, they are an example of a weight-bearing form of exercise. An elliptical cross trainer is comparable to a treadmill in its exertion of leg muscles and the heart. Ellipticals produce an intermediate range of leg motion between that of stationary bikes and treadmills
