ABSTRACT:
An arm curl exercise apparatus is provided. The arm curl exercise apparatus includes a selectable weight mechanism and an inpact lever mechanisms operatively connected thereto. A pair of four bar linkage mechanisms are connected to the free end of the input lever. A pair of handles are rotationally connected to the forward most bar component of the four-bar linkage mechanisms such that the handles follow the same pivoting movement as the forward most bar component, when the four bar linkage mechanisms are pivoted. When utilizing the rotatably mounted handles the user is able to maintain the proper biomechanical alignment of the joints while choosing from a variety of grips. The paths through which the four-bar linkage mechanisms travel enable the handles to travel along a slightly curvilinear upwardly converging and downwardly diverging path which simulates as natural a human musculoskeletal arm curl motion as possible.
