The Arnold press begins with the palms facing the body and rotates outward while pressing overhead, engaging the shoulder through a fuller range of motion than the standard dumbbell shoulder press.
Resistance exercises can be valuable for strength and function, but technique, load, training history and individual health conditions matter. This is a more technically demanding shoulder exercise and may not be an appropriate starting point for people with current shoulder symptoms.
Exhale as you press and rotate upward, inhale as you lower and rotate back down.
Sets
2-3 sets
Reps
8-12 repetitions
Duration
Under 15 minutes
Rest
60-90 seconds between sets
Estimated completion time: Under 15 minutes for the full set of 2-3 sets, including rest between sets.
These are general, real starting points — not an automatic prescription for every user.
Return to the standard dumbbell shoulder press without the rotation, or use lighter dumbbells.
Increase the load gradually once the rotation feels controlled and comfortable, or slow the tempo further.
Primary Muscles
Deltoids
Secondary Muscles
Triceps, Upper chest
Movement Pattern
push
Master the standard dumbbell shoulder press first, since the added rotation increases the technical and shoulder-mobility demand. Choose a load you can control through the full rotating range. Stop if you feel shoulder pinching, pain, or instability.
Spine Considerations
Brace the core throughout to avoid excessive lower back arching during the overhead phase, particularly as fatigue increases.
Joint Considerations
This exercise places genuine additional demand on shoulder rotational mobility and control compared with a standard press. Stop if you feel pinching, catching, or pain anywhere in the rotation.
Suitability depends on the individual — this list isn't an absolute contraindication for everyone in these categories.
Goals
Same movement pattern, different equipment — useful if you don't have what this exercise calls for.
How often can I do this exercise?
A common starting point is 2-3 sessions per week with at least a day of rest for the same muscle group in between, but this depends on your overall programme, recovery, and goals — start conservatively and progress gradually.
What if I don't have a pair of dumbbells?
Try the regression noted above, or browse the Exercise Explorer for a similar movement using different equipment.
Is this exercise safe if I have a current injury or health condition?
This exercise carries specific cautions for some people (see "Who Should Be Cautious?" above) — suitability depends on your individual situation, so check with your doctor or physiotherapist if any of those apply to you.
Is this exercise appropriate for a beginner or intermediate exerciser?
This is classified as intermediate. If it feels too demanding at first, use the regression above and progress once it feels controlled.
