The Arnold press adds rotation to a standard dumbbell press—you start with palms facing you and rotate to palms forward as you press. This rotation recruits all three deltoid heads through a longer range of motion. Named after Arnold Schwarzenegger.
Start with dumbbells at shoulder height, palms facing you. As you press up, rotate your palms to face forward. The rotation should be smooth and continuous, finishing as you lock out. Reverse on the way down.
What muscles does the Arnold Press work?
Why This Exercise Works
The Arnold press is unique among shoulder pressing movements because the rotational component recruits all three deltoid heads through a single continuous movement. The exercise begins with palms facing you (supinated), which places the anterior deltoid in a pre-stretched position similar to a front raise. As you press and rotate to palms forward (pronated), the lateral deltoid progressively takes over, and the posterior deltoid assists with stabilization through the arc of rotation.
The anterior deltoid does the heaviest work during the bottom-to-mid portion of the press where the palms are transitioning. The lateral deltoid peaks in activation during the upper portion as your arms move into the overhead pressing plane. EMG analysis shows the Arnold press produces higher lateral deltoid activation compared to standard dumbbell presses, as Jeff Nippard has noted in his evidence-based shoulder training reviews. This makes it one of the few pressing movements that meaningfully targets side delts.
The rotational component also increases time under tension compared to a straight press. The longer movement arc means each rep takes more time, and the muscles are loaded through a greater range of motion. Dr. Mike Israetel has highlighted that this extended ROM is valuable for hypertrophy because more mechanical work is performed per repetition. However, the rotation demands lighter loads — most lifters use 20-30% less weight than their standard dumbbell shoulder press.
The upper portion of the trapezius assists during the overhead lockout phase, while the triceps contribute to the final pressing motion. The rotator cuff muscles — particularly the infraspinatus and teres minor — work throughout to control the humeral rotation. This makes the Arnold press a surprisingly complete upper body movement.
In MySetPlan programs, Arnold presses appear as either a primary pressing movement on shoulder days or as a secondary press after heavier overhead press or barbell work. They are programmed more frequently in hypertrophy blocks (8-12 reps) than strength blocks, reflecting their role as a muscle-building variation rather than a maximal strength exercise.

What are the best tips for the Arnold Press?
Named after Arnold Schwarzenegger.
The rotation hits all three deltoid heads.
Control the rotation throughout.
Don't rush the movement.
When to Use the Arnold Press
Use Arnold presses when you want complete deltoid stimulation in one exercise. The rotation makes them harder than standard presses, so use lighter weight. Good as a primary press or after heavier straight pressing.
What are common Arnold Press mistakes to avoid?
Rotating too early or late.
Using too much weight.
Rushing through the rotation.
Who should do the Arnold Press?
Intermediate lifters looking to progress their training.
How many sets and reps of Arnold Press should you do?
Recommendation: 3-4 sets of 8-12 reps. Rest 90s.
Muscle Growth
8-12 reps
Rest 90s-2min
Strength
6-8 reps
Rest 2-3min
Endurance

Where to Use in Your Workout
Use as your primary dumbbell shoulder press or as a secondary pressing movement after barbell overhead press. The higher time under tension makes it better suited for moderate rep ranges. Follow with lateral raise isolation work.
Sample Workout Blocks
Hypertrophy: 3x10-12 @ RPE 7-8 (90s rest) | Moderate: 4x8 @ RPE 8 (2 min rest) | Expect to use 20-30% less weight than standard dumbbell press

Variation Details
Standing Arnold Press
Perform standing instead of seated. Adds core stability demand but limits the weight you can use. Good for athletic training.
Single-Arm Arnold Press
One arm at a time. Increases core anti-rotation demand and lets you focus on each side independently. Good for fixing asymmetry.
Seated Arnold Press
Back support version that lets you isolate shoulders more. The most common variation for muscle building.
Dumbbell Shoulder Press
Standard press without rotation. Allows heavier loading for pure pressing strength.
Arnold Press vs Other Exercises
Standard dumbbell press allows heavier loads and is better for pure strength. Arnold press hits all three delt heads through the rotation and builds more balanced shoulders. Use standard presses for heavy work, Arnold presses for hypertrophy and complete deltoid coverage.
Barbell overhead press is the strongest pressing variation and best for strength progression. Arnold press offers more deltoid variety through rotation but with lighter loads. Use overhead press as your primary strength builder, Arnold press for hypertrophy variety.
Lateral raises are pure isolation for side delts. Arnold press is a compound movement that hits side delts through pressing plus rotation. Use Arnold presses for efficient compound training, add lateral raises for dedicated side delt volume.
Frequently Asked Questions About the Arnold Press
Sit on a bench with back support. Hold dumbbells at shoulder height with palms facing you. Press the dumbbells overhead while simultaneously rotating your palms to face forward. The rotation should be smooth and continuous, finishing as you lock out. Reverse the rotation on the way down, returning to palms facing you at the bottom.
The Arnold press works all three heads of the deltoid. The front delts work hardest at the bottom, the side delts engage during the rotation, and the rear delts help stabilize. Your triceps assist at lockout and your upper traps help at the top. The rotation makes it one of the most complete shoulder exercises.
Standard dumbbell press lets you go heavier and is better for pure pressing strength. Arnold press hits more of the deltoid through the rotation and builds wider-looking shoulders. Use both: standard press for heavy strength work, Arnold press for hypertrophy and variety.
Start with 20-30% less than your regular dumbbell shoulder press weight. The rotation increases time under tension and difficulty. If you press 50-pound dumbbells normally, start Arnold presses around 35-40 pounds. Focus on controlling the rotation before adding weight.
Yes, standing Arnold presses work well and add a core stability challenge. However, seated versions with back support let you isolate the shoulders better and use slightly more weight. Standing is good for athleticism, seated is better for muscle building.
For muscle building, do 3-4 sets of 8-12 reps with 90 seconds rest. The exercise works best in moderate rep ranges because the rotation benefits from controlled tempo. Going too heavy forces you to rush the rotation and lose the benefit. Keep reps clean and controlled.
Yes, the Arnold Press can be done at home with a dumbbell. It requires minimal space and is a great option for home workouts targeting shoulders.
