Pressing one dumbbell while the other hand stays empty makes your obliques fight the sideways pull for the whole set, turning a shoulder exercise into serious trunk work. Expect your per-arm weight to drop below half of what you press with two dumbbells. Its sibling with an opposite-arm hold steadies the torso; this version deliberately does not.
How to do the Single Arm Dumbbell Shoulder Press
- Stand with your feet shoulder-width apart and hold a dumbbell in one hand at shoulder level, palm facing forward.
- Engage your core and press the dumbbell straight up overhead, fully extending your arm.
- Pause for a moment at the top, then slowly lower the dumbbell back to shoulder level.
- Repeat for the desired number of repetitions, then switch to the other arm.
Tip: Take a breath and brace before unracking, then press up and slightly back so the bar ends over the middle of the foot.
Muscles worked
Primary
Delts · Shoulders
The front and side delts drive the weight off the shoulders and should carry the load all the way to lockout; the burn builds across the whole shoulder cap.
Secondary
- Triceps — The triceps take over in the top half to lock the elbows, and a weak lockout usually means they need direct work.
- Upper Back
Common mistakes
- Leaning back into an incline — if the lower back arches hard, the chest is doing the work; squeeze the glutes, brace the abs and keep the ribs down.
- Pressing around the head — the bar should travel straight up, so pull the chin back to let it pass, then push the head through at the top.
- Stopping short of lockout — finish with the arms straight and the bar stacked over the shoulders and hips, shoulders shrugged slightly up at the top.
- Elbows drifting behind the bar — keep the elbows slightly in front of the bar at the bottom, with the wrists stacked straight above them.
Where it fits in a workout
Overhead presses go first in a shoulder session or second after bench in a push day. Superset them with a pulldown or pull-up for a vertical push and pull pair.
