    • A chest press exercise machine has a self-aligning pivoting user support on a main frame and an exercise arm which is linked to the pivoting user support to translate movement of the exercise arm into movement of the user support. A user support pivot pivotally connects the user support to the main frame. A connecting link is movably associated with the user engagement device or exercise arm and at least one of the main frame, user support, or user support pivot. A user-activated positioning device controls positioning of the exercise arm in an exercise ready position at the start of an exercise. The user support pivot is positioned so that part of the combined weight of the user and user support is positioned on both sides of the gravitational centerline throughout the exercise movement and a portion of the combined weight passes through the centerline to redistribute the weight as the exercise arm is moved.
    • 胸部按压锻炼机具有在主框架上的自对准旋转使用者支撑件和与枢转使用者支撑件相关联的运动臂,以将运动臂的运动转换成使用者支撑件的运动。 用户支撑枢轴将用户支撑枢轴连接到主框架。 连接链接可移动地与用户接合装置或运动臂以及主框架,用户支撑或用户支撑枢轴中的至少一个可移动地相关联。 用户激活的定位装置在锻炼开始时控制锻炼臂在锻炼就绪位置的定位。 定位用户支撑枢轴,使得用户和使用者支撑的组合重量的一部分位于整个运动运动中的重力中心线的两侧,并且组合重量的一部分通过中心线重新分配作为锻炼的重量 手臂被移动
