ABSTRACT:
A dual function exercise machine, enabling unilateral and bilateral exercise of a limb, includes a pair of lever arms pivotally mounted adjacent to each other on a frame. Each lever arm is slidably mounted through a separate linear bearing sleeve at a point remote from the pivot point and is associated with a separate and independent stack of weights. Each weight stack is slidably mounted on guide bars of the frame. Each sleeve is pivotally connected to a selector bar which is adapted to connect a number of weights to the sleeve to provide resistance during either unilateral or bilateral exercise of a limb. In this manner, one or both corresponding limbs may be exercised with the same or different number of weights connected to each lever arm.
