The arrangement has a carrier (2) via a shaft coupling coupled to an electric motor (1) manoeuvred by the person training to rotate clockwise and counterclockwise dependent upon whether the load is to increase or lessen. When an outgoing shaft on the electric motor is made to rotate clockwise a threaded wt. carrier is screwed down into the wt. magazine (4) and several weights. are screwed into the wt. carrier which increases the load. When the outgoing shaft on the electric motor rotates counterclockwise the wt. carrier is screwed upwards out of the wt. magazine and the load reduces. After the load is adjusted, the person training draws in a main wire (8) anchored in a wire force distributor (7) which distributes the force in a main wire to two wires applied to the uppermost wt. plate in the wt. magazine. |
