Dumbbell Arnold Press
Stand with your midsection firm and back straight. With a dumbbell in each hand have your arms bent and your palms facing the front of your shoulders.
Raise the dumbbells upwards, bringing your elbows out to the sides, rotating your hands so your palms are facing frontwards and so your arms are extended above you.
Lower the dumbbells down again to starting position, rotating your hands so that your palms are facing your shoulders.
