1. A dual-function treading exerciser comprising:
- a lower body exerciser and an upper body exerciser, said upper body exerciser including;
a frame joined to the lower body exerciser;
a movable handle assembly including a pair of pulling devices mounted on said frame, and a rotary shaft journalled substantially vertically on said frame, each of said pulling devices including, a pulley disposed on said frame, a pull cord wound on said pulley, a handgrip fastened to an end of said pull cord and movable rearwardly to unwind said pull cord from said pulley, and a biasing unit for biasing said pull cord to wind around said pulley when said cord is pulled rearwardly and is subsequently released;
a flywheel assembly mounted on said rotary shaft, said flywheel assembly including a flywheel and a pair of magnetically conductive rings disposed respectively and on opposite sides of said flywheel;
a unidirectional bearing disposed between said rotary shaft and each of said pulleys so as to rotate said rotary shaft synchronously with said pulleys only when said pulleys rotate in a direction in which said pull cords are unwound from said pulleys; and
,a magnetic resistance device disposed adjacent to said flywheel assembly so as to provide resistance to rotation of said flywheel assembly.
