Dumbbell Arnold Press
Also known as: arnold shoulder press
Starting palms-in at chin height and rotating to palms-forward at lockout adds range a standard seated press never covers, keeping the front delts loaded through the extra travel. The rotation costs some weight, so expect to press lighter than your usual dumbbells and treat it as an 8-to-12-rep hypertrophy movement rather than a strength test.
How to do the Dumbbell Arnold Press
- Sit on a bench with back support and hold a dumbbell in each hand at shoulder level, palms facing your body and elbows bent.
- Press the dumbbells upward until your arms are fully extended and your palms are facing forward.
- Rotate your wrists as you lift, so that your palms are facing forward at the top of the movement.
- Pause for a moment at the top, then slowly lower the dumbbells back to the starting position.
- Repeat for the desired number of repetitions.
Tip: Squeeze the bar hard and keep the wrists straight over the elbows through the whole rep.

Primary
Delts · Shoulders
The front delts assist every press and take over on Bradford and behind the neck variations.
Common mistakes
- Elbows flaring wide — on horizontal presses keep the elbows at roughly 45 degrees from the torso; pressing overhead, keep them under the weight instead.
- Losing the shoulder blade position — on bench-style presses set the shoulder blades back and down and keep them there; overhead, let the shoulder blades rotate up naturally with the arms.
- Bouncing or rushing the bottom — control the bar down and pause for a beat before driving up, especially on decline and close grip variations.
- Not committing to a variation — Bradford presses, skull presses and the like are hybrids; pick a fixed range and stick with it for the whole set.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Strength | 4–5 × 3–6 | 2–3 min |
| Muscle growth | 3–4 × 6–12 | 90–120 s |
| Endurance | 2–3 × 12–20 | 60 s |
Presses are the main movement in a push session and should go first or second. Superset them with a row or pulldown for a push and pull pair using the same bench or station.

Frequently asked questions
What muscles does the Dumbbell Arnold Press work?
The Dumbbell Arnold Press primarily works the delts. It also involves the triceps and pectorals, which assist the movement and stabilise the joints.
Is the Dumbbell Arnold Press good for beginners?
It is rated intermediate, so it suits people who already train regularly. Beginners can still do the Dumbbell Arnold Press with light load and a spotter or coach watching the first few sessions; if it feels awkward, pick an easier variation from the alternatives below first.
What can I do instead of the Dumbbell Arnold Press?
If you cannot do the Dumbbell Arnold Press, try the No Back Support Dumbbell Arnold Press, the Dumbbell Cuban Press or the Dumbbell Push Press. Each of them trains the delts through a similar movement, so you can swap them in without changing the rest of the workout.
How many sets and reps should I do?
It depends on your goal. For the Dumbbell Arnold Press, a sensible starting point is strength: 4–5 × 3–6 with 2–3 min rest; muscle growth: 3–4 × 6–12 with 90–120 s rest; endurance: 2–3 × 12–20 with 60 s rest. Put it early in the session while you are fresh, before isolation work for the same muscles.
