An elliptical machine simulates the non-impact walking stance by being a stationary exercising machine. The elliptical machine’s most striking feature is that it provides a weight bearing for both the legs. The standard ellipticals operate with the upper body by using the handles and the lower body by employing pedals.

These days many treadmill users are switching to using the elliptical machine as it appeals the trainer because it has a low impact on the joints and still ensures a brisk workout.

An elliptical machine works ultimately for cardiovascular strength and helps to burn calories to improve the aerobic capacity. An elliptical machine is said to deliver a ‘non-impact conditioning’ as it allows the body to emulate a jogging motion without causing a serious strain on the trainer’s joints which occurs more on a treadmill.

An elliptical machine is equipped with moveable handles and a cross training ability which allows the trainer to exercise the upper body properly (pectoralis major, triceps, biceps and deep core muscles).
Reverse stride is another unique option that an elliptical machine offers. It allows the trainer to stride in reverse, which activates the muscle groups of lower-body muscles (gluteus maximus, quadriceps, and hamstrings). It also proves to be a fun activity in the middle of a workout.

The perceived output on ellipticals is low. One can set the program accordingly. This essentially means that the trainer is asked to rate their perceived output. So, it typically operates based on the actual output of their heart rate. This is a strategic method of burning almost the same number of calories with lesser effort.
Elliptical works not just for the upper and lower body, as the trainers to go forward and backward – its simultaneous target is the other group muscles.

In terms of losing fat, the ellipticals deliver almost the same intensity of workout as compared to when people use the stair climber or a treadmill. A 12-week regular exercise regime with nutritional food diet would bring in the change you envisioned.
