An elliptical trainer is cardio machine that is similar to a treadmill. The difference between an elliptical machine and a treadmill is that an elliptical emulates a run or a walk with the foot pads moving with the exerciser. Instead of walking on a platform like a treadmill, the elliptical foot pads move with the runner, which reduces the amount of stress on the knees and joints.
Function
An elliptical machine is used as a cardio workout device. It's beneficial for people who are unable to exercise outdoors, and it's common in gym environments. A cardio workout can be a part of a fat-loss regimen, and an elliptical can be an integral part of that process. The elliptical machine emulates a regular run outdoors, except the runner does not have the impact on the bones and joints. Therefore, the elliptical is beneficial for people with injuries or those who are overweight.
Workouts
An elliptical facilitates a low-impact run or jog, and it can be a tool for a walker. Some ellipticals also have arm extensions where you move your arms along with the run. This helps tone your arms and chest while burning more fat. You can set the resistance, so you can burn more fat and challenge your cardiovascular system.
Features
An elliptical normally has a computer layout at its control panel. Aside from the arm extensions and the foot platforms, the elliptical has a similar control panel to a treadmill. The elliptical has a display that shows how many calories you have burned, and it tells you the distance traveled in miles. Some ellipticals have metal sensors where you can place your thumbs or hands to calculate your heart rate. The control panel often has a place for a water bottle.
Types
The types of ellipticals are based on price. A cheaper elliptical is less sturdy, and it does not have as many options on the control panel, such as preprogrammed workouts. A cheaper elliptical may not have frames that support the runner, and some of them do not have the arm handles that increase the cardio output. More expensive ellipticals have all the options, but they can cost several thousands of dollars.
Time Frame
A good elliptical workout lasts about 30 minutes. Some exercisers increase the workout time to 45 minutes to an hour. An elliptical can burn off hundreds of calories after a long workout. Exercisers should practice 30 minutes a day, three times a week at minimum.
