ABSTRACT:
A multi-functional exercise device includes a base plate having opposed first and second end portions and an intermediate portion between the first and second end portions. An upright hollow housing has a bottom end mounted on the base plate at an intermediate section of the first end portion of the base plate so as to form two tread sections on the base plate on two sides of the housing, and a top end which has a top plate mounted thereon. The top plate is formed with a passage unit for access into an interior of the housing. The base plate is formed with an elbow-receiving depression at the intermediate portion thereof. The elbow-receiving depression is located between the two tread sections and immediately adjacent the housing. A driving unit includes a horizontal shaft which is disposed inside the housing and which is mounted rotatably on the base plate, a driving rope having a first end portion attached to the shaft and a second end portion extending out of the housing through the passage unit, a hand-gripping member secured to the second end portion of the driving rope, and a biasing unit for biasing the shaft to rotate so as to wind normally the driving rope on the shaft. A damping unit is disposed inside the housing and is associated operably with the shaft. The damping unit provides resistance to damp rotation of the shaft.
