The Arnold Press is an intermediate compound exercise that builds shoulder strength using a vertical push with rotation. By adding a rotational movement to a standard overhead press, you increase the range of motion and time under tension.
This movement primarily targets your anterior deltoid and lateral deltoid. Because it is a pressing motion, your triceps also work hard as supporting muscles to help extend the arms at the top. All you need is a pair of dumbbells to get started.
How to do it
Sit on a bench with back support and hold a pair of dumbbells in front of your face with your elbows bent and palms facing you.
- Brace your core and keep your back flat against the bench.
- Begin pressing the dumbbells overhead while simultaneously rotating your wrists outward.
- Continue the upward press and rotation until your palms face forward at the top of the movement.
- Fully extend your arms without locking your elbows.
- Lower the dumbbells slowly while rotating your wrists inward.
- Return to the starting position with your palms facing you in front of your shoulders.
Sets, reps and load
Aim for 3 sets of 8 to 12 repetitions. Rest for 60 to 90 seconds between sets to allow your shoulders to recover.
Choose dumbbells that are slightly lighter than what you would use for a standard overhead press to account for the rotational movement.
Common mistakes
- Rushing the rotation. Sync the rotation with your press so your palms face forward exactly as you reach the top.
- Arching the lower back. Press your lower back firmly into the bench and brace your core.
- Dropping the elbows. Stop the downward phase when the dumbbells are just in front of your shoulders to maintain tension.
- Using momentum. Perform the movement strictly with your shoulders and triceps without bouncing the weight at the bottom.
Make it easier or harder
Easier
- Seated dumbbell overhead press
- Alternating single-arm Arnold press
Harder
- Standing Arnold press

Before you load it up
- Pressing or reaching overhead can irritate a painful shoulder. If raising your arm overhead hurts, use a partial range or a different angle and get it checked.
