An exercise apparatus is disclosed herein, including a frame, a rotating
assembly, two supporting rods, two swing arms, two links, and two pedals.
The front ends of the supporting rods are connected respectively to two
connecting points of the rotating assembly, and the rear end of each
supporting rod moves back and forth along a corresponding track. The
front ends of the links are connected respectively at two swing ends of
the swing arms. Each pedal is mounted at the rear end of a corresponding
link and pivotally coupled to a corresponding supporting member. The
distance between the bottom of a circular path of the connecting points
and the tracks is smaller than 10 cm. The length of the supporting rod is
smaller than two times diameter of the circular path. The longitudinal
horizontal distance between the front edge of the closed path and the
rear edge of the circular path is smaller than 20 cm. The rear ends of
the supporting rods are located between the front ends and rear ends of
the pedals.
