Abstract
An embodiment of the present invention provides an elliptical trainer including structures featuring a first amplitude, a second amplitude, and a third amplitude. By the driving of cranks and the combination of the three amplitudes, the elliptical trainer's pedals move along a closed ellipse path. In addition, the first amplitude is more than twice or three times of the third amplitude, resulting in a wide adjustment range of the stride of the pedal. Accordingly, the elliptical trainer is applicable to users of various heights.
