An exercise device is intended for developing arm and wrist, and is composed of a joint seat, a joint housing, a bearing member, an elastic element, two handlebars, and two torsion-resisting elements. The joint seat, the joint housing and the bearing member are fastened coaxially and pivotally in conjunction with the elastic element. The joint seat and the joint housing are provided with a handlebar fastened therewith. The torsion-resisting elements are located in the handlebars such that one end of the torsion-resisting element is retained by the joint housing or the joint seat, and that another end of the torsion-resisting element is retained by the handlebar.
