An exercise device includes a frame having a set of guide links pivotally supported thereupon. Each guide link supports a foot engaging link at one end thereof. The guide links are reciprocated back and forth by a set of intermediate links which engage a set of cranks which rotate about a second pivot point. A control link joins the foot link to the intermediate link and operates to vary the angle between the guide links and the foot links, as the guide links reciprocate. This device provides a very natural running and stepping action for a user who is positioned on the foot links.

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.
