Abstract:
An exercise device to simulate various types of stepping and striding motions, comprising:a frame defining a rear pivot axis, the frame configured to be supported on a floor; a first and second foot link, each foot link including a first end portion and a second end portion and a foot support therebetween; a coupling system associated with the first end portion of each foot link for coupling the first end portion of each foot link to the rear pivot axis so that the first end portion of each foot link travels in a closed path relative to the rear pivot axis; a guide associated with the frame and operative to engage and direct the second end portions of the foot links along preselected reciprocating paths of travel as the first end portions of the respective foot links travel along their paths of travel, so that when the exercise device is in use and when the second end portion of the foot link travels forwardly from a rearmost position the heel portion of the user's foot initially rises at a faster rate than a toe portion thereof, and when the second end portion of the foot link travels rearwardly, from a foremost position, the heel portion of the user's foot initially lowers at a faster rate than the toe portion, said guide including a roller assembly for rollably supporting the second end portions of the first and second foot links; and a lift mechanism for raising and lowering the roller assembly relative to the rear pivot axis.
