The dumbbell lateral raise is one of the most effective isolation exercises for building the lateral head of the deltoid, the muscle responsible for shoulder width and definition. It’s a staple in shoulder workouts and a key movement for anyone looking to build a strong, balanced upper body.
How to Do the Dumbbell Lateral Raise
- Start Position: Stand tall with a dumbbell in each hand, arms at your sides, palms facing inward. Keep a slight bend in your elbows.
- Movement: Raise the dumbbells out to your sides until your arms are parallel to the floor. Do not swing your body or let the weights rise above shoulder level.
- Pause and Lower: Briefly pause at the top, then lower the weights back down slowly and under control.
Form Tips
- Lead with your elbows, not your hands
- Avoid shrugging your shoulders
- Keep your core engaged and posture tall
- Use light to moderate weight to prevent cheating with momentum
Recommended Sets, Reps, and Daily Weight Guidelines
To improve shoulder size and definition:
- Beginner: 3 sets of 10–12 reps with 5–10 lb dumbbells
- Intermediate: 4 sets of 12–15 reps with 10–20 lb dumbbells
- Advanced: 4–5 sets of 12–20 reps with 15–30 lb dumbbells, adding partial reps or drop sets for more intensity
Perform this exercise 2 to 3 times per week with at least one rest day between sessions to allow for recovery.
Muscles Worked
- Primary: Lateral deltoid
- Secondary: Anterior deltoid, supraspinatus (part of the rotator cuff), upper trapezius (minimally, if form is strict)
Progression and Improvement
- Increase reps before adding weight
- Use slow negatives to increase time under tension
- Incorporate variations like cable lateral raises or leaning lateral raises for continued adaptation
Consistent use of the dumbbell lateral raise will add width and shape to your shoulders, making your upper body look more powerful and proportionate.
