Stand erect with a dumbbell on each hand (palms facing your torso), arms extended on the sides.
>>Lift the dumbbells by elevating the shoulders as high as possible while you exhale. Hold the contraction at the top for a second. Tip: The arms should remain extended at all times. Refrain from using the biceps to help lift the dumbbells. Only the shoulders should be moving up and down.
>>Lower the dumbbells back to the original position.
>>Repeat for the recommended amount of repetitions.
