A method and system for exercising areas of the body such as the neck, the wrist, the ankle, and the torso which require a wide range of motion and effective resistance over this range. A first member can rotate in relation to a frame and a user interface (second member) is moveable in relation to the first member. As a user pushes on the user interface in any of an X-Y direction the user interface travels in a controlled arcuate three-dimensional motion. The user interface is attached to a lead (rope or cable) which holds the user interface at a rest position and also provides a force on the user interface in the opposite direction of the users force. The lead is attached to an adjustable resistive system and/or a damping system that resists the movement of the sliding assembly. The lead spools in and out of from a central location through a fairlead. Many mechanical configurations can be utilized to allow the user interface to travel in an arcuate path in the direction which it is pushed. It is preferable that the path of the user interface corresponds to the rotation of the users push point about his bone socket or vertebra pivot. One way to implement the arcuate path is to place the pivot(s) of the mechanical members on the same plane (X and/or Y plane) as the users joint to be exercised. Other mechanical configurations can be implemented which act as though (virtual pivot points) they have a pivot point on the X-Y plane but in fact the pivot points do not have to be on the X-Y plane. The force exerted by the user can measured over the entire range of motion using a strain gauge or a pressure gauge and position sensors. The fairlead and resistive system is placed on a third member which allows the fairlead to be moved thus changing the rest position of the user interface and the start location for the exercise. The location of the user interface in relation to the pivot points can be adjusted and thus the path traveled by the user interface can be modified.
