Stand up straight with your arms by your sides.
Hold a weight in each hand.
With your arms straight, lift them directly away from you, out to the side.
When your arms are at approximately 30 degrees away from your side, hold them in this position.
Keeping both arms at the same angle, shrug your shoulders up towards your ears.
Control the movement as you lower your shoulders back down, and then repeat.
Ensure your arms stay at the same angle away from the sides of your body throughout.
