ABSTRACT:
A compact exercise device includes a pair of crank arms pivotably supported on a frame for rotation about a pivot axis. Each crank arm engages a respective intermediate link at its first end. A second end of each intermediate link travels on a guide member so that as the crank arms rotates, the first end of each intermediate link traces an arcuate path, and the second end of each intermediate link traces a reciprocating path. The device includes a pair of foot links, each foot link is coupled, through a first end thereof, to a respective one of said intermediate links at a point between the first and second ends thereof; a second end of each foot link engages another guide member which directs it along a preselected path of travel, as the intermediate link is moved by the crank arm. The device provides a range of foot and leg motion simulating a natural running and stepping action.
