Stationary exercise device

An exercise device comprising:

• a frame configured to be supported on a floor, said frame having a first and a second pivot axis defined thereupon;
• a first and a second guide link, each guide link having a first and a second attachment point defined thereupon, each guide link being pivotally attached, through its first attachment point, to said frame at the first pivot axis thereof;
• a first and a second foot link, each foot link being pivotally attached to a respective one of said first and second guide links through the second attachment point thereof;
• a first and a second crank arm, each being pivotally attached to said frame at said second pivot axis so as to be rotatable thereabout;
• a first and a second intermediate link, each having a first end mechanically coupled to a respective one of said guide links, and a second end mechanically coupled to a respective one of said crank arms, so that rotation of said first and second crank arms about said second pivot axis causes said respective first and second guide links to pivot about said first pivot axis;
• and
• a first and a second control link, each having a first end mechanically coupled to a respective one of said foot links, and a second end mechanically coupled to a respective one of said intermediate links, each of said control links being operative to vary an angle defined between its respective foot link and its associated guide link, as said guide link pivots about said first pivot axis.
