Dumbbell Arnold Press

How to do it

1. 1

   Sit or stand tall holding a dumbbell in each hand at shoulder height — elbows bent, palms facing toward you.

2. 2

   Breathe out as you press the dumbbells up and rotate your palms to face forward at the top — arms fully straight overhead.

3. 3

   Breathe in as you lower them back down and rotate your palms back to face you.

4. 4

   That's one rep — the rotation is the key part. Repeat.

Where you should feel it: The fronts and sides of your shoulders.
