Abstract:
1. An exerciser for the sake of training the abdominal muscle group, wherein the operator is induced to twist his upper and lower bodies in opposite directions; and wherein the exerciser includes a coupling mechanism and a rotating disc mechanism for the lower limb of the operator to stand thereon and engaged with a first bevel gear of the coupling mechanism so as to be rotatable in a lateral direction, a rotating handlebar mechanism for the upper limbs of the operator to hold thereon and engaged with a second bevel gear of the coupling mechanism rotatable in the lateral direction, and the coupling mechanism further comprising an intermediate bevel gear engaged with the first and the second bevel gears for synchronically and reversely coupling the rotating disc mechanism and the rotating handlebar mechanism such that application of a rotational force to either the rotating disc mechanism or the rotating handlebar mechanism induces a synchronized reverse rotation in the other of the rotating handlebar mechanism and the rotating disc mechanism.
