ABSTRACT:
A resistance arrangement of a waist-twisting machine, wherein the waist-twisting machine having a bottom base, a foot-rotating disc, and a handrail frame. The operation of the foot-rotating disc imparts a motion to a lateral post coupled with the handrail frame such that the hands and the feet rotate in opposite direction. Two driven arms are pivotally attached to the bottom base, and a plurality of elastic elements are interposed between the driven arms. Moreover, a bumping post is positioned between the driven arms for limiting the driven arms to a proper return position. One of the driven arms corresponding to the exercise direction will be extended outwards by a contact roller at the bottom of the lateral post when the lateral post is moved by an external force. At that time, another driven arm that is not moved will stay there to act as a fixing end. Accordingly, the elastic elements may be pulled to produce an expected exercise resistance.
