Stand next to a bench, feet shoulder-width apart. Hold a dumbbell with a neutral grip. Hinge at the hips, keeping your back straight, and place a hand on the bench for support. Raise the dumbbell laterally to shoulder height, maintaining a slight bend in your elbow. Pause, then slowly lower.
Maintain a straight back. Lift with your shoulder, not your arm, to target the rear deltoid. Control the movement; avoid momentum. Engage your core for stability. Keep your head aligned with your spine.
