Individuals looking for a low-impact exercise machine as an alternative to a treadmill might want to consider an elliptical. Designed with parts that move in the shape of an ellipse, or oval, these machines can provide a full-body cardiovascular workout. Understanding the premise of an elliptical can benefit your exercise regimen
Definition
An elliptical machine is unique in that its moving parts operate in the shape of an ellipse to simulate a running stride. According to the Merriam-Webster Dictionary, the word "elliptical" refers to any object that is either shaped or moves in the shape of a geometric ellipse. An ellipse looks similar to an oval or an elongated circle. An elliptical rower or machine features two leg components that move in an ellipse when in motion. They are propelled by your leg muscles while standing on the machine.
Motion
Stand on the designated foot areas of the machine while bracing yourself with your hands and arms on a handle or brace on top of the machine's frame. You then propel your legs in a motion similar to running or riding a bicycle. The combination of muscle and gravitational forces move the foot pedals along the ellipse-shaped track within the frame of the machine, causing you to run in place.
Variations
In addition to elliptical machines that are propelled exclusively by your leg muscles, there are also full-body ellipticals that incorporate your arms. These machines feature two long arm bars similar to what a skier would hold for support. You use your arms in combination with your legs to propel the machine along its internal elliptical track.
Benefits
One of the main benefits of an elliptical machine is the low-impact nature of the workout. Your feet should not lose contact with the legs of the elliptical, making the machine ideal for patients recovering from knee surgery or other procedures, such as ankle or foot surgery.
