Lateral raise setup
Stand tall, dumbbells at the sides, arms slightly bent (15-20 degrees of elbow flexion). Brace the core, shoulders pulled down and back, neck neutral.
Some lifters benefit from a slight forward lean (5-10 degrees) which keeps the side delt under tension at the bottom of the rep.
The raise
Lift the dumbbells out to the sides, leading with the elbows. The hands stay slightly below elbow height through the rep. Rise until the upper arms are roughly parallel to the floor.
Lower under control. Don’t let the dumbbells crash back to the start position.
Why technique matters more than load
The lateral raise is one of the most form-sensitive isolation exercises. Heavy weight executed with bad form (yanking the dumbbells up with shrugs and trap engagement) trains the traps, not the side delts.
Light weight, slow tempo, full range, and eccentric control produce 10x the side-delt development of heavy sloppy reps.
Common faults
Shrugging during the raise: traps engage and pull the shoulders up. Fix: keep shoulders pulled down throughout, lighter weight if shrugging happens automatically.
Internally rotated arms (palms facing forward): can cause shoulder impingement. Fix: thumbs slightly forward and up, hand position like pouring water out of a jug.
Going above parallel: traps take over above shoulder height. Fix: stop at the parallel position; further range is not better.
Programming
The lateral raise is the workhorse side-delt exercise. Most lifters under-train side delts relative to front and rear, producing a “narrow shoulder” appearance even with developed chest and back.
For hypertrophy: 4-6 sets of 12-20 reps at RPE 8-10. Side delts respond well to high frequency (3-5 sessions per week) and high volume.
Mechanical drop sets work well: heavy strict lateral raises, then leaning lateral raises (more range), then cheat reps to extend the set.
When to swap
Lifters with shoulder discomfort can swap to cable lateral raise (constant tension through the range, more forgiving on shoulder position) or to Egyptian lateral raise (one arm at a time holding a stable post for a deep stretch position).
