Lateral shoulder raise with dumbbells seated on a stability ball

Raise the arms in the required plane to a range you can control without shrugging. Lower slowly while keeping the neck relaxed. Prioritize control over speed. Maintain useful tension through the range and deliberately reset the starting position before the next repetition.

Do not turn the final repetitions into fast or partial movements. Aim to load abdominals, shoulders and lower back without sacrificing position; at intermediate level, progress control first and then add load, repetitions or complexity. On unstable surfaces, master the position with light resistance first; stability should limit difficulty before load does.
