Patent ID: 8388504

Claim:
A weight training machine comprising a frame and a moment arm weight resistance mechanism, the moment arm weight resistance mechanism comprising: a) a cantilevered moment arm pivotally attached to the frame at a pivot point; b) an adjustable weight attached to the moment arm; c) a weight adjusting drive for adjusting the adjustable weight along the moment arm; d) an actuating means operatively connected to the moment arm weight resistance mechanism, wherein the weight on the moment arm creates a moment about the pivot point, wherein the degree of weight resistance can be controlled by a user by movement of the adjustable weight along the moment arm, wherein the moment arm weight resistance mechanism is variable for providing increased or decreased amounts of weight resistance and can be varied by a user during an exercise motion, and wherein moving the actuating means causes the pivoting of the moment arm about the pivot point thereby actuating the moment arm weight resistance mechanism.
