A standing isolation arm exercise performed with a dumbbell using a neutral (hammer) grip, working one arm at a time. The movement involves curling the dumbbell upward by flexing the elbow while keeping the upper arm close to the torso and minimizing shoulder involvement. This standing variation allows for natural body stability demands while maintaining strict form, and it emphasizes controlled lifting followed by a slow eccentric phase to maintain constant tension through the arms and forearms across the full range of motion.
