An isolation arm exercise performed on a preacher bench using a cable machine and a single rope attachment with a neutral (hammer) grip. The working arm is supported against the angled pad while the cable provides constant tension as the elbow flexes to curl the rope upward. The movement emphasizes strict control with minimal shoulder involvement, followed by a slow and steady lowering phase to maintain continuous tension through the arms and forearms across the full range of motion.
