An upper body exerciser having a frame which supports a rotatable head that has an axis of rotation. The head has two end plates with radially extending slots in which cross rods are reciprocably radially movable. A track mounted to the frame below the axis of rotation provides a sloping support for cross-rods below the axis so that a person hanging from such a rod moves the cross rod down and draws the next one toward him in a sequence simulating a "monkey bar" movement.
