(WO9749460-A1)      The device comprises a frame which has a pivot axis defined on it. The frame is configured to be supported on a floor. The device has two foot links. Each foot link has two ends with a foot supporting portion located between them. A coupling system associated with the first end of each foot link, pivotally connects the first end of each foot link to the pivot axis to allow the first end to travel in an arcuate path relative to the pivot axis. A guide is supported by the frame and is operative to engage and direct the second ends of the foot links along preselected reciprocating paths of travel as the first ends of the respective foot links travel along arcuate paths of travel.    When the exercise device is in use and when the second end of one of the foot link travels forwards from a rearmost position the heel portion of the user's foot initially rises at a faster rate than a toe portion of it. When the second end of the foot link travels rearwards, from a foremost position, the heel portion of the user's foot initially lowers at a, faster rate than the toe portion. The control system selectively automatically changes the elevation and angular orientation of the guide relative to the frame to alter the path travelled by the foot supporting portion of the two links.    ADVANTAGE -   Simulates range of stepping motions. Jogging and running are simulated without imparting shock to user's body joints as in excercise treadmills.
