Abstract: A chest peak contractor preferably includes a platform, a pair of stanchions, a pair of vertically adjustable telescoping poles and a pair of armature hand assemblies. The pair of stanchions extend upward from opposing sides of the platform. Each stanchion is sized to receive one of the vertically adjustable telescoping poles. A top of each telescoping pole is terminated with a pivoting joint. Each armature device handle assembly is mounted to a top of the respective telescoping pole. Each armature handle assembly preferably includes a handle, a proximal axle support tube, an armature crossbeam, a distal hanger, a pair of backstop rails, a ring bolt backstop, an axle, and a weight holder. The handle is rotatably retained in the pivoting joint. An end of the handle is secured to the proximal axle support tube.

Abstract: One embodiment of an exercise device for the chest wherein to a base two large rotating sheaves are placed in a horizontal plane, turned by poles in the vertical plane to which rotating handles are attached. A cord attached to a pulley wraps around each sheave as the poles are rotated from a position of from behind the back to in front of the chest of the exerciser (or vice versa). The sheaves are placed in horizontal planes above or below the exerciser. Thus two functions of the chest, transverse adduction and medial rotation of the arms are multiplexed into one movement.

Abstract translation: 用于胸部的锻炼装置的一个实施例，其中对于基部，两个大的旋转滑轮放置在水平面中，所述水平平面由旋转手柄附接到的垂直平面中的极转动。 随着杆从背后的位置旋转到锻炼者胸部的前方（或反之亦然），连接到滑轮的绳索缠绕在每个滑轮周围。 滑轮放置在锻炼者上方或下方的水平面上。 因此，臂的胸部，横向内收和内侧旋转的两个功能被复合成一个运动。
