Step exercise apparatus.

摘要

A step exercise apparatus comprises a first foot operated pulley (108), a second foot operated pulley (110) and a user selectable lever (222) adapted to operate a resiliently biased connector (182) having pins (184,186) for disengagably entering in apertures (148,150,152;158,160,162) in the pulleys (108,110) so that the pulleys (108,110) are locked together for cooperative rotative movement in an interdependent operative mode at one position of the lever (222) and the pulleys (108,110) are disengaged one from another for independent rotative movement upon withdrawal of the pins (184,186) from the apertures (148,150,152; 158,160,162) in an independent operative mode at a second position of the lever (222). <IMAGE>
