AN EXERCISER WITH COMBINED STEPPING AND TWISTING FUNCTIONS INCUDES A BASE FRAME (20), A PAIR OF ELONGATED PEDAL MEMBERS (24) AND TWO LINKAGES (37). EACH OF THE PEDAL MEMBERS (24) HAS A FRONT END CONNECTED PIVOTALLY TO THE FRONT END PORTION OF THE BASE FRAME (20). A ROTARY SEAT (30) IS CONNECTED PIVOTALLY TO THE FRONT END PORTION OF THE BASE FRAME (20) ABOUT A VERTICAL AXIS EXTENDING THROUGH THE FRONT END PORTION OF THE BASE FRAME (20). AN UPRIGHT HANDLE (33) EXTENDS ALONG THE VERTICAL AXIS AND IS CONNECTED TO THE ROTARY SEAT (30). EACH OF THE LINKAGES (37) INTERCONNECTS THE ROTARY SEAT (30) AND THE FRONT END OF A CORRESPONDING ONE OF THE PEDAL MEMBERS (24) IN ORDER TO PERMIT ROTATION OF THE ROTARY SEAT (30) AND THE UPRIGHT HANDLE (33) WHEN THE PEDAL MEMBERS (24) ARE PIVOTED ALTERNATELY ON EITHER SIDE OF THE BASE FRAME (20).FIGURE 1
