ABSTRACT:
An exerciser includes a base frame, a rotary plate, a driven rod and an elastic cord. The base frame has an upright rod, a transverse rod and two U-shaped clamping members. A plurality of adjusting pulleys are mounted to the upright rod. Each of the end portions and the intermediate portion of the transverse rod has a pulley. The rotary plate has a circular portion and an eccentric portion. The circular portion is mounted rotatably to a pivot shaft of the upright rod and has a plurality of positioning holes. The eccentric portion has left and right pulleys rotatably mounted to its rear side face. The driven rod has an upper end connected rotatably to the pivot shaft, a positioning pin extending slidably through the driven rod and extendible into one of the positioning holes in order to position the driven rod relative to the rotary plate at a selected angle, and a transverse bar connected to a lower end of the driven rod. The elastic cord has two ends which are connected respectively to the end portions of the transverse rod. The elastic cord passes over the right pulley of the rotary plate, under the pulleys of the transverse rod and over the left pulley of the rotary plate under tension.
