ABSTRACT:
A dual-direction pulley system is disclosed in conjunction with an exercise machine. The pulley system provides resistance to a pivotally mounted actuator lever when the lever is rotated clockwise and when the lever is rotated counterclockwise. In a preferred embodiment the dual-direction pulley system provides resistance for a seated leg curl/extension exercise machine such that a user can perform leg curls and leg extensions from a single seated position.
