An isolation arm exercise performed using a single handle attached to a low cable pulley with a preacher bench for support. The working arm is positioned face-down on the pad while the cable provides constant resistance as the elbow flexes in a reverse (pronated) grip curl. The movement emphasizes strict control with minimal shoulder involvement, targeting the forearm and brachialis more heavily than a standard curl, followed by a slow and controlled lowering phase to maintain continuous tension throughout the range of motion.
