An elliptical cross trainer having a double-recessed crank in match of a load-coupling mechanism installed at the external side of a crank support. In this way, the gap of two pedal planks arranged parallel to each other can be reduced, thereby achieving the natural opening space of both human feet. Meanwhile, a hanging support together with suspension arm is connected with two pedal planks such that the pedal planks can create an optimal exercise path corresponding to the exercise pace of both human feet.
