The dumbbell seated one arm Arnold press is a single-arm overhead shoulder exercise that works the deltoids by rotating the dumbbell from a front-rack position to a full press, with the triceps assisting the lockout. Performed seated with one arm at a time, it lets you focus on each shoulder individually for balance and full range of motion.
Dumbbell Seated One Arm Arnold Press: So führst du sie aus
- 1Sit on a bench with back support, plant both feet on the floor, and brace your core with your chest up and spine tall.
- 2Hold a single dumbbell at shoulder height in front of you with your palm facing your body and your elbow tucked in.
- 3Keep your free hand resting on your thigh or the bench to stay stable, and avoid leaning toward the working side.
- 4Press the dumbbell upward while smoothly rotating your wrist so your palm turns to face forward.
- 5Continue pressing until your arm is fully extended overhead, with the dumbbell stacked over your shoulder.
- 6Pause briefly at the top without locking the elbow harshly or shrugging the shoulder up.
- 7Lower the dumbbell under control, reversing the rotation so your palm faces your body again at shoulder height.
- 8Complete your reps on one side, then switch the dumbbell to the other arm and repeat.
Technik-Tipps
- Move through the rotation smoothly and continuously rather than pausing halfway, so the turn and the press blend into one motion.
- Keep the dumbbell tracking over your shoulder at the top instead of drifting forward or behind your head.
- Brace your core and keep your back against the pad to stop your torso from twisting toward the working arm.
- Use a controlled tempo, especially on the way down, to keep tension on the shoulder through the full range.
- Start lighter than you would for a strict press, since the rotation makes the shoulder work harder through a longer path.
Häufige Fehler
- Leaning or twisting toward the working arm to help push the weight up, which removes load from the shoulder and strains the lower back.
- Using momentum or a leg drive to launch the dumbbell, which cheats the rep and reduces tension on the deltoid.
- Rushing the rotation so the palm-turn happens too late or too early, which makes the movement jerky and stresses the shoulder joint.
- Shrugging the shoulder up toward the ear at the top, which shifts work to the traps and crowds the shoulder joint.
- Going too heavy and shortening the range of motion, which limits the shoulder development the full movement is meant to build.
Häufig gestellte Fragen
What muscles does the dumbbell seated one arm Arnold press work?
It works the shoulder muscles (deltoids) as the primary movers, with the triceps assisting to extend the arm at the top of the press. The seated position keeps the focus on the working shoulder.
Why do it one arm at a time instead of both?
Pressing one arm at a time lets you focus on each shoulder individually, which helps even out strength differences between sides and lets you concentrate fully on the rotation and range of motion.
What is the difference between the Arnold press and a regular shoulder press?
The Arnold press adds a rotation, starting with your palm facing you and turning it to face forward as you press. A regular shoulder press keeps the palm facing forward the whole time, so the Arnold press moves the shoulder through a longer path.
Is the dumbbell seated one arm Arnold press good for beginners?
Yes, with a light dumbbell. Beginners should master the smooth rotation and a controlled tempo before adding weight, and the seated, single-arm setup makes it easier to learn the movement one side at a time.
How many sets and reps should I do?
Three to four sets of 8 to 12 reps per arm is a sensible default for building the shoulders. Use a weight you can control through the full rotation on every rep without leaning or swinging.
