The technology of the elliptical machine can be defined as a way to incorporate the numerous mechanisms and linkages to try to create the preferred pattern of movement of a pair of feet in the fitness industry. This type of preferred movement is intended to imitate the natural path of the hip joints, knee, and ankle that are experienced when running, jogging, striding, or walking.

Basically, the technology of the elliptical machine is made up of a crank arm. Like that on the pedal crank of a bicycle, that is attached to a bar at one end and revolves around an axis at the other end. When the crank rotates the opposite end of the bar rotates in a linear pattern. Because one end of the bar moves linearly while the other end rotates in a circular motion, the points between the two ends of the bar move in an elliptical pattern. The points of the bar that are one end of the bar move in flatter and thinner ellipses which are closer to a straight line and those that are closest to the crank move in more circular and wider circular ellipses which are closer to a circle.

The most obvious benefit of the technology of the elliptical machine is that there is practically no impact on the back and lower limbs. The foot pedal and the foot are in constant contact, unlike a treadmill where the foot of the user is continually raised from the running surface and then strike the surface when it returns. This fitness machine effectively eliminates all impact.

Stair stepper exercises machines also have an impact force. While the foot is in constant contact with the foot pedal, the foot pedal reverses direction virtually instantaneously. Basically, the foot pedal moves in one direction must stop and then must move in the opposite direction. The force that is needed to reverse this movement of the machine causes impact to the lower bodys joints.

This fitness machine incorporates a mechanism that moves in a continually smooth motion which doesnt have the effects of this reversal of direction. The exercise that a person gets on this fitness machine is weight bearing as opposed to an exercise bike and will actually inhibit the onset of osteoporosis.

Also, while cycling is a safe way to improve cardiovascular conditioning that is well recognized. This fitness trainer provides a more functional pattern of movement. Because this fitness trainer simulates the pattern of natural walking, they are great for the upper body component of exercise. There are numerous other types of exercise equipment that either as a result of their pattern as in cycling, or mechanical structure as in the treadmills, isnt as adaptable to a total body workout.
