When it comes to building your shoulders, there are a few staple exercises that come to mind. Dumbbell lateral raises are one of the most popular shoulder exercises, due to their proven benefits in developing lean muscle mass and strength. Designed to stimulate the mediolateral head of the deltoids, the lateral raise is one strength training movement that can isolate your shoulders for a well-defined physique. We are going to break down the perfect form for dumbbell lateral arm raises, their benefits, and the muscles worked.

What Is Lateral Raise 

The lateral raise is a foundational isolation exercise that targets the anterior (front) and lateral (side) heads of the deltoid muscle. Often performed with dumbbells or cables, this movement is ideal for sculpting wider shoulders and enhancing upper body symmetry.

When incorporated with other deltoid exercises, rear delt, or shoulder exercises such as push press, and front raise the lateral raise can be a great accessory lift to help develop the anterior and lateral deltoid in your training split.

According to McAllister et al., Journal of Strength and Conditioning Research, pressing movements underemphasize the lateral deltoid, highlighting the need for isolation work like lateral raises to achieve balanced growth.

Dumbbell Lateral Raise: Muscles Worked

The lateral raise primarily targets:

• Lateral Deltoid

• Anterior Deltoid

Secondary and stabilizer muscles engaged include:

• Trapezius

• Rhomboids

• Erector Spinae

• Core musculature

• Triceps (long head)

• Wrist Extensors

• Adductor Magnus

EMG research by Boettcher et al., Journal of Shoulder and Elbow Surgery confirms that lateral raises create some of the highest levels of middle deltoid activation among all shoulder exercises.

Benefits of the Dumbbell Lateral Raise

1. Core Stability

Though it's primarily a shoulder movement, the lateral raise requires postural strength and spinal stability.

• Improves balance and coordination

• Reinforces upright posture

• Strengthens core engagement in functional movement

2. A Well-Defined Physique

To build capped shoulders and a classic V-taper, targeting the lateral delts is essential. Lateral raises isolate this region to:

• Widen shoulder profile

• Enhance symmetry

• Improve aesthetics for both physique athletes and everyday lifters

3. Functional Strength & Athletic Performance

Your shoulders are involved in nearly every upper body movement. Strengthening them enhances performance in:

• Pressing exercises (bench, overhead press)

• Throwing sports

• Cross-functional training

Kibler et al., American Journal of Sports Medicine emphasize that exercises like lateral raises can enhance glenohumeral stability, reducing injury risk and improving overhead mechanics.

How to Perform the Dumbbell Lateral Raise

Step-by-Step Instructions

1. Start in a Standing Position
   Grab a pair of dumbbells and stand tall with your feet shoulder-width apart.

2. Set the Arms
   Let the dumbbells hang by your sides with palms facing your body, arms slightly bent.

3. Engage and Raise
   While maintaining a tight core, lift the dumbbells out to the sides. Keep a slight forward tilt (as if pouring water from a jug).

4. Reach Parallel
   Raise until your arms are level with your shoulders, not higher.

5. Pause at the Top
   Briefly hold the contraction.

6. Lower with Control
   Return the dumbbells to your sides slowly to maintain tension.

7. Repeat
   Perform 10–15 reps, 3–4 sets.

Pro Tip: Avoid swinging or shrugging—lateral raises are most effective with light-to-moderate weight and slow, controlled tempo.

Lateral Raise Variations for Maximum Gains

Dumbbell vs. Cable: Which is Better?

• Dumbbells: Convenient and effective for most settings

• Cables: Provide constant tension throughout the lift, especially effective in peak contraction and eccentric loading

In a study by Andersen et al., European Journal of Applied Physiology, cable lateral raises showed superior EMG activation due to consistent mechanical resistance.

Try These Alternatives:

• Seated Lateral Raise – Greater deltoid isolation

• Cable Lateral Raise – Smooth tension curve

• Leaning Dumbbell Raise – Extended time under tension

• Resistance Band Raise – Joint-friendly with elastic feedback

• Reverse Lateral Raise – Rear deltoid focus

Time Under Tension and Hypertrophy

Lateral raises can significantly benefit from eccentric tempo manipulation. Slowing down the lowering phase (3–4 seconds) increases:

• Metabolic stress

• Muscle fiber recruitment

• Hypertrophic response

A 2019 review in Sports Medicine concluded that controlled tempo training leads to greater hypertrophy, especially when focused on eccentric overload.

Common Mistakes to Avoid

• Too Much Weight
  Leads to momentum-based lifting and reduced activation.

• Lifting Above Shoulder Height
  Over-recruits traps and decreases deltoid isolation.

• Shrugging or Bending Wrists
  Keep shoulders low and wrists neutral.

• Poor Tempo
  Rushing the movement kills time under tension.

Advanced Programming Tips

Mechanical Drop Sets

Start with strict lateral raises, then shift to partials or cheat reps to finish the set strong. This extends time under tension and forces the delts to fatigue fully.

Pre-Exhaustion Supersets

Perform lateral raises before overhead presses to pre-fatigue the delts and improve their contribution to compound lifts.

A study by Brennecke et al., JSCR found that pre-fatiguing muscles increased their activation in subsequent multi-joint lifts.

Where to Add Lateral Raises in Your Routine

• Frequency: 2x/week is ideal

• Volume: 3–4 sets of 10–15 reps

• Best Placement: After compound shoulder exercises or in supersets

• Sample Superset:

  • A1: Seated Lateral Raise – 12 reps

  • A2: Cable Front Raise – 12 reps

  • Rest 60 sec – Repeat 3 rounds

Nutrition Tips for Shoulder Development

Building rounded delts takes more than reps. Fuel your gains with:

• Protein: 1.6–2.2 g/kg/day

  • 👉 Swolverine Whey Isolate

  • 👉 Swolverine Plant Protein

• Carbohydrates: Needed for high-rep training volume

• Healthy Fats: Support hormones and recovery

  • 👉 Swolverine Krill Oil

Supplements to Boost Shoulder Growth

• Creatine Monohydrate
  Increases power and performance
  👉 Creatine

• POST Workout Recovery
  Pea protein, Carb10™, glutamine, coconut water for muscle recovery
  👉 POST

• Greens + Reds
  Inflammation support and micronutrients
  👉 Greens + Reds

Final Takeaway: Why Lateral Raises Belong in Every Upper Body Program

The lateral raise is not just another shoulder movement—it’s a staple for building aesthetic, powerful, and injury-resistant delts. By incorporating it into your training, focusing on tempo, and avoiding common errors, you’ll create the muscle tension and activation needed for long-term gains.

Train smart, pair it with effective programming and proper nutrition, and let your shoulders do the talking.
