Arnold Press
Muscles worked
Instructions
- 1Sit on an exercise bench with back support and hold two dumbbells in front of you at about upper chest level with your palms facing your body and your elbows bent. Tip: Your arms should be next to your torso. The starting position should look like the contracted portion of a dumbbell curl.
- 2Now to perform the movement, raise the dumbbells as you rotate the palms of your hands until they are facing forward.
- 3Continue lifting the dumbbells until your arms are extended above you in straight arm position. Breathe out as you perform this portion of the movement.
- 4After a second pause at the top, begin to lower the dumbbells to the original position by rotating the palms of your hands towards you. Tip: The left arm will be rotated in a counter clockwise manner while the right one will be rotated clockwise. Breathe in as you perform this portion of the movement.
- 5Repeat for the recommended amount of repetitions.

About Arnold Press
The Arnold press is a dumbbell pressing movement popularised by Arnold Schwarzenegger. You start palms facing you in front of the shoulders, then rotate the wrists during the ascent to finish palms forward, arms extended. This rotation engages the front then the side delts in turn, giving a wider range and more complete shoulder work than the classic press. The triceps assist the lockout at the top. Control the rotation and the descent smoothly: the load will be a bit lighter than on the dumbbell press, which is normal given the increased range.

lightbulbExecution tips
- lightbulbStart with palms facing you, dumbbells at chin height
- lightbulbRotate the wrists so palms face forward at the top
- lightbulbKeep the core braced and back pressed into the bench
- lightbulbUse lighter loads than on a standard shoulder press
- lightbulbExhale on the push and inhale as you control the descent
warningCommon mistakes
- warningRotating too fast, which breaks tension on the delts
- warningArching the lower back to help push the weight up
- warningBanging the dumbbells together at the top
- warningDropping too low and straining the shoulder joint
- warningLetting the elbows drift too far behind the torso at the start
tuneVariations and alternatives
- tuneSeated Arnold press — backrest-stabilized version, the most common one
- tuneStanding Arnold press — adds extra core stability work
- tuneSingle-arm Arnold press — isolates each shoulder and fixes asymmetries
- tuneCable Arnold press — keeps constant tension through the whole range
person_checkWho it's for and level
The Arnold press suits intermediate to advanced lifters who already master the classic dumbbell press and want to add more range and rotation to their shoulder work. Beginners can try it with very light loads to learn the pattern, but should first build a solid base with the standard press. It particularly suits people who want rounder, more complete shoulders rather than pure strength gains, as well as those looking to improve shoulder rotational mobility and control. It is less suitable for anyone dealing with shoulder pain.
shieldSafety and precautions
The Arnold press involves shoulder rotation that can be uncomfortable with shoulder impingement, rotator cuff tendinopathy, or anterior shoulder pain: in those cases favor a neutral-grip or fixed-grip press instead. Warm up the shoulders with light rotations before the set and always start noticeably lighter than your standard press to get used to the path. Avoid excessively arching the lower back to help the push, which stresses the lumbar spine, and don't lower the dumbbells below ear level to avoid straining the joint. Stop the movement if you feel pinching or sharp pain.
calendar_monthWhere to place it in your program
Place the Arnold press as a main or secondary exercise in a shoulder or push session, after heavy strength work like the military press if the goal is strength, or first if the goal is hypertrophy and mind-muscle connection. Aim for 3 to 4 sets of 8 to 12 reps with 60 to 90 seconds of rest between sets, keeping 1 to 2 reps in reserve to preserve the quality of the rotation. One to two sessions per week is enough within a balanced program. Progress in small load increments once the rotation technique is smooth and free of lower-back compensation.
helpFrequently asked questions
Is the Arnold press better than the regular dumbbell press?
It adds rotation that recruits the lateral delt more, but allows less weight. Both movements complement each other.
Should I do it seated or standing?
Seated with a backrest stabilizes the torso and limits cheating, making it ideal for the shoulders. Standing demands more core work.
Should I rotate the wrists through the whole range?
Yes: the gradual wrist rotation during the ascent is the whole point of the exercise, recruiting the side delt more. Without it, you are back to a plain dumbbell press.
How much lighter should the load be compared to a regular dumbbell press?
Expect around 10 to 20% less than a standard dumbbell press. The larger range of motion and the rotation phase demand more control, so start light and add weight once the technique feels solid.
Is the Arnold press suitable for beginners?
Yes, as long as you learn the rotation with a light load before adding weight. It is a great exercise for learning to feel the front and side delts working in sequence.
Can it be done on a machine, or only with dumbbells?
The signature rotation requires free dumbbells. There is no satisfying machine equivalent, since a guided machine would lock the wrist into a fixed path.
How often should I train this exercise to progress?
One to two sessions a week is enough, worked into a broader shoulder or push program. Leave at least 48 hours of rest between sessions that heavily load the deltoids.
Does the Arnold press work the triceps?
Yes, like any vertical pressing movement, the triceps kick in mainly at the top to lock out the arms, but they stay secondary compared to the deltoids.
