An exercise machine includes a base on which a swiveling frame is pivotally mounted. The swiveling frame is provided at one end with a seat, and at another end with a leg-supporting frame pivoted therewith by a position controlling seat. The base is further provided with a backrest frame pivoted therewith by an adjustment seat. The leg-supporting frame and the backrest frame can be adjusted to be positioned at a specific angular position so as to provide a user of the exercise machine with the damping force of a desired magnitude.
