A variable resistance exercise device provides a variable resisting force in response to a user applied force. The variable resistance exercise device includes at least one rotating force transmitting means for inputting a user applied force as a rotational force to be resisted, and at least one force transmission member for transmitting the user applied force. The user applied force is resisted by varying the viscosity of a viscosity variable fluid which surround plates rotated by the user applied force. Thus a braking force is applied to actively resist the user applied force. In accordance with the invention, a multi-configurable multi-programmable exercise device is provided which may be used in a variety of exercise modes to provide a resistive force to a user-applied force during a range of motion of a particular exercise. In a preferred embodiment of the present invention, a variable resistor resists a user-supplied force in one rotational direction only. A gear and clutch system translates a reciprocating user-supplied force, corresponding to a reciprocating range of motion, into the one rotational direction. |
