<p>A variable resistance exercise device (10) provides a variable resisting force (14) in response to a user applied force. The variable resistance exercise device includes at least one rotating force transmiter (16) for inputting a user applied force as a rotation force to be resisted, and at least one force transmission member (24) for transmitting the user applied force. The user applied force is resisted by varying the viscosity of a viscosity variable fluid (41) which surround plates (40) 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 resistance resists a user supplied force in one rotational direction only.</p> |
