Single-Arm Dumbbell Overhead Press
- Beginner
- Dumbbell
Pressing one dumbbell at a time turns an ordinary overhead press into an offset-load exercise. You hold the dumbbell at shoulder height with the palm forward and the elbow under the wrist, brace the abs and glutes, then press overhead and lower under control. Working each side separately finds and fixes strength differences a barbell hides, and the standing single-arm version stays approachable enough for beginners. Single-arm pressing also raises core involvement, and the deltoids, triceps and trapezius do the moving.
How to do the Single-Arm Dumbbell Overhead Press
- Stand with your feet shoulder-width apart holding one dumbbell.
- Bring the dumbbell to shoulder height with your palm facing forward and your elbow under your wrist.
- Brace your abs and squeeze your glutes so your ribs stay down.
- Press the dumbbell overhead by extending the elbow and flexing the shoulder.
- Finish with your biceps close to your ear and the arm almost straight.
- Lower under control to shoulder height, complete the reps, then switch arms.
Muscles worked
- Primary:
- Shoulders
- Secondary:
- Triceps, Core, and Traps
Why train it
- One arm at a time exposes and corrects strength differences between shoulders.
- The offset load makes the trunk resist side bending on every rep.
- Needs one dumbbell and no rack, so it fits small and home setups.
Common mistakes
- Leaning away from the working arm, which turns the press into a side bend.
- Letting the elbow drift out from under the wrist, which leaks force before the press starts.
- Dipping the knees to start the rep, which makes it a push press and cuts the shoulder work.
- Pressing the dumbbell out in front of the head, which shortens the range and stalls the lockout.
