PURPOSE: A tool for three dimensional anaerobic exercise of the upper back is provided to safely and diversely exercise the upper back and maximize the growth of muscle of the upper back by using various resistant systems. CONSTITUTION: The tool for three dimensional anaerobic exercise of the upper back exercises the upper back along the three-dimensionally twisted movement caused by angular movement of a handle(3) using the distance between a handle link(1) and a sub link(2). The handle link(1) is disposed at both sides of the upper part of a base frame. The sub link(2) is fixed onto the base frame at a distance from the handle link(1) by a ball joint(6). Over the handle link, a handle side lever of L-shape having a plurality of handles is disposed. A tangent line at the center of the three-dimensionally twisted movement caused by the angular movement of the handle(3) forms 60 to 120 degrees to a chest support pad.
