The present invention is an exercise machine providing elliptical strides in substantially lateral directions. The elliptical motion of the pedals is basically a combination of a looped motion of a loop motion means and a reciprocating motion set by a motion guide means following a predefined path. The loop motion means connects the motion of a left pedal to the motion of a right pedal so that the movement of both pedals is dependent. Substantially lateral motions of the left pedal and the right pedal follow lateral predefined paths set by a left motion guide means and a right motion guide means. The motion guide means can be a simple reciprocating arm that rotates about a pivot point on a base frame and its distal end guiding the motion of the pedal; a track that is either fixed on or moving in reference to the base frame; a linkage system, such as a four bar linkage system, pivotally fixed at two or more points on the base frame providing a point, on the linkage system, that moves in reference to the base frame and provides a specific predefined path; or a combination of any two or all of above creating a mechanism that produces a desired path for a point in the motion guide means. |
