Patent ID: 8066621

Claim:
An apparatus comprising: a frame; a first member having at least one pivot point rotatable in relation to the frame about the at least one pivot point; a second member coupled to the first member and moveable in relation to the first member; a user interface coupled to the first member and engageable with the at least a portion of the human body, such that the first and second member confine movement of the user interface to locations defined by a three dimensional arcuate surface a resistance system coupled to the frame and; a lead coupled to the user interface and coupled to the resistance system, the lead to extend from the resistance system a first distance as the user interface moves the first distance from the start location in a fore direction, the lead to extend from the resistance system the first distance as the user interface moves the first distance from the start location in a left direction, and the lead to extend from the resistance system the first distance as the user interface moves the first distance from the start location in a right direction, where the left and right direction are perpendicular to the fore direction.
