Begin seated on a bench, extend your arms overhead with your dumbbells having your palms face outwards.

Keeping your wrists above your elbows at all times, lower the dumbbells so that you have created a 90 degree angle at your elbows, and then rotate your arms inward toward your body with a slight twist so that your palms are now facing you out in front of your face.

Bring the dumbbells back to the sides of your head with your palms facing outwards and press them back up to the starting position before repeating.
