The lateral raise isolates the lateral (side) deltoid — the muscle that builds shoulder width and that capped, 3D look. It is a small movement that requires strict form over heavy weight.
Muscles worked
Primary: Lateral deltoid.
Secondary: Anterior deltoid, Trapezius.
Equipment: Dumbbells · Difficulty: Beginner.
How to do the lateral raise
- Stand holding a light dumbbell in each hand at your sides, palms facing in.
- With a slight bend in your elbows, raise the dumbbells out to the sides.
- Lead with your elbows and stop when your arms reach shoulder height (roughly parallel to the floor).
- Pause briefly at the top.
- Lower under control back to your sides. That is one rep.
Common mistakes to avoid
- Going too heavy and swinging the weights up with momentum — the side delts are small; use lighter weight and strict form.
- Shrugging the traps up to assist; keep the shoulders down.
- Raising the arms above shoulder height, which hands the work to the traps.
