Common Dumbbell One Arm Shoulder Press Mistakes

Leaning away from the working arm to get the dumbbell moving, which bends the spine sideways under load.

Squeeze the glute on the pressing side and keep both hips level. If a lean is needed to finish the rep, the weight is too heavy.

Pressing the dumbbell up in front of the face instead of over the shoulder joint.

Finish every rep with the wrist, elbow, and shoulder stacked and the dumbbell sitting directly above the ear.

Stopping the descent at chin level so the delt never reaches a full stretch.
