Abstract: An exercise device includes a base, a first platform and a second platform. Both platforms move between a forward position and a rearward position along each own path relative to the base. The exercise device includes a flexible member operatively coupled with the first and second platforms. Furthermore, a resistance mechanism is coupled with the flexible member and configured to resist movement of at least one of the first platform and the second platform. The resistance mechanism includes a disc positioned parallel to the base and is configured to allow the disc to rotate relative to a vertical axis of the base. In addition, the flexible member is configured to allow the disc to rotate reciprocally in response to movement of the first platform or second platform.
