Exercise apparatus with elliptical foot motion

摘要

An exercise apparatus includes a frame; left and right first cranks rotatably mounted on the frame; left and right second cranks rotatably mounted on the frame; left and right rails rotatably interconnected between respective first cranks and respective second cranks; left and right foot supports movably mounted on respective rails; left and right rocker links pivotally mounted on the frame and operatively connected to respective foot supports; and left and right drawbar links movably interconnected between respective cranks and respective rocker links. The resulting assembly constrains the rails to move through respective circular paths relative to the frame, and constrains the foot supports to move back and forth relative to the rails.
