About
Stand with your feet about shoulder-width apart.
Hold a light dumbbell in each hand with your palms facing up or slightly forward at your thighs.
Brace your core and keep your chest up.
Raise both dumbbells out to the sides in a wide arc.
Continue the arc until the dumbbells meet above your head.
Lower the dumbbells back down using the same wide arc with control.
Repeat for the desired number of repetitions.
