Abstract
Weightlifting apparatus, especially for performing curling exercises, includes a rectangularly shaped frame having weights mounted on opposite extremities thereof. Gripping handles are secured to and disposed within a pair of spaced apart rings which are rotatably mounted within the frame. A cable trained around and interconnecting the rings synchronizes the rotation of the handles. A spring interconnecting the rings applies a biasing force resisting rotation of the handles.
