The single-arm dumbbell press trains each shoulder independently while demanding intense core anti-lateral flexion. Pressing one dumbbell overhead while the other side has nothing forces your obliques and deep core muscles to work overtime preventing you from leaning.
When to use it
Use to address imbalances or challenge core.
Who it's for
Intermediate lifters looking to progress their training.
Don't lean—this is the whole point of going unilateral. Keep your torso perfectly vertical throughout. If you find yourself tilting, the weight is too heavy. The core challenge should feel as demanding as the shoulder work.

Stand or sit with a dumbbell at shoulder height.
Press the dumbbell overhead with one arm.
Keep your core tight to prevent leaning.
Lower with control for optimal results.
Complete all reps before switching arms.
Requires core stability.
Great for addressing imbalances.
Don't lean to the side.
Control the weight throughout.
Use single-arm pressing to address strength imbalances between shoulders, or when you want pressing that builds core strength simultaneously. They work well after bilateral pressing when you want to continue shoulder work while challenging your core differently.
Leaning to the side.
During any pressing movement like the Single-Arm Dumbbell Press, this mistake reduces how effectively your Front shoulders can produce force. Focus on the muscle you're trying to work — if you can't feel your Front shoulders driving the movement, something is off.
Not engaging core which reduces stability and power transfer.
Losing your brace during the Single-Arm Dumbbell Press can make the rest of your position less stable. Tighten your midsection before the rep and maintain steady tension while the load moves.
Using too much weight.
Loading more weight than you can control on the Single-Arm Dumbbell Press often creates compensations that shift work away from your Front shoulders. Reduce the load until each rep follows the intended path.

These ranges illustrate ways to organize training. They are not an individual prescription. Adjust them for the exercise, your experience, and the rest of your program.
Heavier loads can be useful for developing maximum strength. The range shown is an example, and the load must match your current technique and capacity.
Muscle growth can occur across different loads and repetition ranges. This example is not a uniquely effective zone; your overall program and effort also matter.
This is an example of a longer set. A repetition target alone does not establish joint safety or whether the exercise is appropriate for you.
Example: 3 sets of 8-10 reps per arm. Rest 60s.
Background for resistance exercises: the 2026 ACSM position stand covers healthy adults, and a load-comparison review found similar muscle growth across loads in studies using sets taken to muscular failure. These findings do not validate every exercise-specific range shown here or require training to failure.
This is one example of how Single-Arm Dumbbell Press could sit inside a complete workout. Your plan may use different movements after Ely checks your assessment.
