An exercising apparatus for training the muscles of a human body includes a frame supporting a crank on a shaft which is attached to a pair of identical disks. The disks define several cam paths along which a cable is guided whose other end is connected to a stack of weight plates. By guiding the cable about the various cam paths, each muscle can be exercised in each phase of motion according to its capability in view of the respectively changing moment arms.
