    • An exercise apparatus having right and left foot pedals with a forward end thereof pivotally supported by right and left swing arms and a rearward end thereof pivotally supported by right and left lift arms. In an alternative embodiment, a lift cable is used. A swing control member interconnects the swing arms to provide a dependent action with the rearward movement of one pedal causing the forward movement of the other, and an interconnect member interconnects the rearward end portions of the pedals to provide a dependent action with the downward movement of the rearward end of one pedal causing the rearward end of the other pedal to move upward. The swing control member and the interconnect member are operatively disconnected such that while the forward and rearward movement of the right and left pedals have dependent action and the downward and upward movement of the right and left pedals have dependent action, the forward and rearward movements and the downward and upward movements are independent of each other. A resistance device resists rearward movement of the right and left pedals.
    • 一种具有右脚踏板和左脚踏板的运动装置,其前端由左右摆臂枢转地支撑,其后端由左右提升臂枢转地支撑。 在替代实施例中,使用升降缆索。 摆动控制构件将摆臂互连以提供依赖动作,其中一个踏板的向后运动导致另一个踏板的向前运动,并且互连构件将踏板的后端部分互连以提供依赖动作, 一个踏板的后端导致另一个踏板的后端向上移动。 摆动控制构件和互连构件可操作地断开,使得在左右踏板的向前和向后运动具有依赖作用并且左右踏板的向下和向上运动具有依赖动作时,前后运动和 向下和向上的运动是相互独立的。 电阻装置抵抗左右踏板的向后运动。
