i miss the nautilus super forearm machine they had at my college. It would do forward and reverse wrist curls, and pronation/supination twisting motion all on one machine...you could switch so quickly from one to the other and superset all 4 exercises and by the time you were done on it your forearms would be so swelled with blood and the veins popping out all over you would feel like fuckin popeye.
That machine was awesome, I wish they had one at my gym.
