Dumbbell One Arm Shoulder Press
Description
The dumbbell one-arm shoulder press is a unilateral vertical pressing exercise where you press a single dumbbell overhead one arm at a time. Training one arm at a time exposes and corrects left-right imbalances, trains core anti-lateral-flexion stability, and allows greater focus on each pressing rep.

Dumbbell One Arm Shoulder Press Instructions
- Stand with feet shoulder-width apart, holding a dumbbell in your right hand at shoulder level, palm facing forward.
- Place your left hand on your hip or extend it out for balance.
- Brace your core hard. Keep your torso upright — do not lean away from the dumbbell.
- Press the dumbbell straight up overhead until your arm is fully extended.
- At the top, the dumbbell should be directly above your right shoulder.
- Lower the dumbbell under control back to shoulder level. Pause briefly before the next rep.
- Complete all reps on the right side, then switch to the left.
- Resist the temptation to lean away from the weight. The anti-lean is what trains the core.
