Sit upright on a bench holding a barbell with a narrow grip behind your head. Keeping your upper arms steady, lower the bar toward the back of your neck by bending at the elbows, then extend back up by contracting your triceps. Maintain a controlled motion and avoid excessive shoulder movement to focus on triceps activation.
