1. A stationary exercise apparatus, comprising:
- (a) a frame having a base, a side portion, a front, and a back;
(b) first and second supporting members, each supporting member having a first end portion and a second end portion, the first end portions of the first and second supporting members respectively coupled to the frame to rotate about a first axis;
(c) first and second swing members, each swing member having an upper portion and a lower portion, the lower portions of the first and second swing members respectively pivotally joined to the second end portions of the first and second supporting members, the upper portions of the first and second swing members respectively pivotally connected to the side portion of the frame at points that define a swing axis;
(d) first and second control links respectively pivotally connected to the first and second supporting members, each control link having a first end portion, a second end portion, and a central portion, wherein the first end portions of the first and second control links are movably coupled to the frame, the central portions of the first and second control links are respectively joined to the first and second supporting members so that the second end portion of each control link extends upwardly above the supporting members; and
(e) first and second pedals respectively coupled to the second end portions of the first and second control links, the first and second pedals moving along a closed path while the first ends of the first and second supporting members are being rotated about the first axis and the second ends of the first and second supporting members are reciprocating with the lower portions of the first and second swing members.
