The Dumbbell Single Arm Z Press is an effective shoulder exercise that targets your deltoids while engaging your core for stability.
- Start seated on the floor with your legs extended in front of you.
- Hold a dumbbell in one hand at shoulder height, palm facing forward.
- Press the dumbbell overhead while keeping your core tight and back straight.
- Lower the dumbbell back to the starting position and repeat.
How to perform the Dumbbell Single Arm Z Press
- Set up. Set up in a stable, balanced starting position appropriate for the Dumbbell Single Arm Z Press using your dumbbell.
- Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your deltoids.
- Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.
Coaching cues
- Move with intent — every rep should feel deliberate, not rushed.
- Drive force through your deltoids rather than momentum.
- Keep your breathing steady: exhale on the hard part, inhale on the reset.
Common mistakes
- Using too much weight and losing positional control.
- Cutting the range of motion short and missing the target muscle.
- Letting your spine round or hyperextend instead of staying neutral.
