Muscles worked
Instructions
- 1Stand with a dumbbell in each hand. Raise the dumbbells to your shoulders with your palms facing forward and your elbows pointed out. This will be your starting position.
- 2Extend one arm to press the dumbbell straight up, keeping your off hand in place. Do not lean or jerk the weight during the movement.
- 3After a brief pause, return the weight to the starting position.
- 4Repeat for the opposite side, continuing to alternate between arms.

About Alternating Dumbbell Shoulder Press
The alternating dumbbell shoulder press is a variation of the standard dumbbell press where one arm presses at a time while the other stays fixed at shoulder height. This split-timing forces the torso to resist the rotational force created by the unilateral press, adding an anti-rotation core challenge to a classic pressing movement. It's a great tool for building trunk stability alongside the deltoids and triceps, while also surfacing and helping correct strength differences between the two sides of the body.

helpFrequently asked questions
Why alternate instead of pressing both arms together?expand_more
Alternating adds a core stability challenge and helps surface strength asymmetries between the arms.
Is this harder than the standard dumbbell press?expand_more
Yes, the core works harder to resist rotation, which makes the exercise more demanding at the same load.
