structure when folded.
[0028] For the operation of the abdominal exerciser of the present
invention, reference had to FIGS. 2 to 5A, 5B and 5C. The first and
second support frame 31, 35 of the framework 30 are extended
outward. The protruded engaging blocks 33, 37 of the first and
second clutching members 32, 36 are used to restrict the first and
the second support frame 31, 35, as shown in FIG. 5C. When the
first and second supporting frame 31, 35 have been extended to a
certain angle, the extension will be stopped and the abdominal
exerciser can be set on the floor, as shown in FIG. 2. The user can
sit onto the seat pad 13 and the legs of the user will hook at the
leg-hooking rod 24 of the leg-hooking module. Based on the length
of the leg, the length of the leg-hooking rod 24 can be adjusted by
