Dumbbell upright shoulder external rotation

Stand with your feet shoulder-width apart and hold a dumbbell in each hand with your palms facing your body. Raise your arms out to the sides until they are parallel to the ground, keeping your elbows slightly bent. Rotate your arms externally, bringing the dumbbells up towards your head while keeping your elbows in the same position. Pause for a moment at the top, then slowly lower the dumbbells back to the starting position. Repeat for the desired number of repetitions.
