How to perform Arnold Dumbbell Press
- Sit 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.
- Now to perform the movement, raise the dumbbells as you rotate the palms of your hands until they are facing forward.
- Continue lifting the dumbbells until your arms are extended above you in straight arm position. Breathe out as you perform this portion of the movement.
- After 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.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Shoulders (primary): raises and rotates the arms and drives everything overhead.
- Triceps (secondary): straightens the elbow to lock out every press and pushdown.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the ribs down and the glutes tight so the lower back doesn't arch to 'help' the weight up.
- Each side works on its own, so match the depth and speed of both arms and don't let the stronger side take over.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Breathe out on the effort and in on the return, keeping one steady rhythm across the set.
Common mistakes
- Pressing with the lower back arched instead of a braced, stacked torso.
- Letting the dumbbells drift apart or clang together at the top instead of controlling the path.
- Chasing weight jumps before the current load feels solid on every rep.
