ABSTRACT:
A gymnastic apparatus comprises a base, a treading member, a handle rod, a seat rod, a first linking member, and a second linking member. The base has a support frame mounted thereon. The treading member has a rotary shaft pivoted to the support frame, two pedal rods fastened respectively to both ends of the rotary shaft, and two pedals pivoted respectively to the free ends of the two pedal rods. The handle rod is provided at the top end thereof with two hand grips and pivoted at the bottom end thereof to the base. The seat rod is pivoted at the bottom end thereof to the base and is provided at the top end thereof with a seat cushion. The first linking member is disposed between the rotary shaft of the treading member and the handle rod such that the rotational motion of the rotary shaft is caused to link with the angular displacement motion of the handle rod. The second linking member is located between the handle rod and the seat rod such that the handle rod is caused to link with the angular displacement motion of the seat rod.
