Abstract
A multipurpose gymnastic apparatus comprises a frame unit, a pulley unit, and a load carrying unit. The frame unit is composed of a ladder frame having a front end on which a dual-purpose pushing and rotating device is mounted, a chair set and a leg stretching device. The pulley unit comprises a plurality of independent ropes running through the pulleys and having free ends connected with the pushing and rotating device and the leg stretching device. The load carrying unit is capable of being lifted and lowered by the ropes. The pushing and rotating device comprises two wheel fitting members, two arresting pieces, and a protective rod. The ropes running on the two fitting members can be actuated by the two arresting pieces to permit a chest building exercise to be done while the ropes can be pressed against by the protective rod to permit an arm building exercise to be done.
