Dumbbell Arnold Press
Description
The dumbbell Arnold press, named after Arnold Schwarzenegger, is a shoulder press variation that adds a rotation to the bottom and top of the lift. Starting with palms facing your body and rotating to palms facing forward at lockout, the movement recruits all three heads of the deltoid in a single rep — front, side, and rear — making it one of the most complete single-exercise shoulder builders.

Dumbbell Arnold Press Instructions
- Sit on a bench set upright with back support, or stand. Hold a dumbbell in each hand at shoulder level with palms facing your body (like the top of a bicep curl).
- Your elbows should be in front of your body and the dumbbells held close to your shoulders.
- Brace your core and pull your shoulders back.
- Begin pressing the dumbbells overhead. As you press, rotate your wrists outward so that at lockout, your palms face forward.
- At the top, your arms should be fully extended overhead with palms facing forward — the same finish position as a standard shoulder press.
- Reverse the movement by lowering the dumbbells while rotating your palms back toward your body.
- Finish the descent with palms facing your body and elbows in front of your torso.
- The rotation should be smooth and continuous throughout the press, not abrupt at the top or bottom.
