How to Do Lateral Raises: Build Wider Shoulders

If you want wider shoulders, you need lateral raises. This isolation exercise directly targets the medial (side) deltoid—the muscle that creates shoulder width and that coveted V-taper.

But lateral raises are butchered more often than almost any other exercise. Too much weight, too much momentum, and terrible form turn what should be a precision movement into a full-body swing.

Here's how to do lateral raises correctly.

Why Lateral Raises Work

The lateral raise isolates the medial deltoid in a way compound movements can't match. While overhead pressing works shoulders, it emphasizes the anterior (front) deltoid. The medial deltoid needs direct work for maximum development.

Muscles worked:

• Medial deltoid (primary): The side of your shoulder
• Anterior deltoid: Assists, especially if you lean forward
• Supraspinatus: Rotator cuff muscle, initiates abduction
• Traps: Can take over if form breaks down

The Basic Lateral Raise

Setup

1. Stand with feet shoulder-width apart
2. Hold dumbbells at sides, palms facing in (neutral grip)
3. Slight bend in elbows—lock this angle in
4. Slight forward lean from hips (10-15 degrees)
5. Core engaged, shoulders down

Execution

1. Raise arms out to sides
2. Lead with elbows, not hands
3. Stop when arms are parallel to floor (shoulder height)
4. Pause briefly at the top
5. Lower under control to starting position

Key Form Points

At the top:

• Arms parallel to floor
• Elbows slightly bent
• Hands at or slightly below elbow height
• Shoulders down, not shrugged

Throughout:

• Same elbow bend maintained
• No swinging or momentum
• Controlled in both directions
• Focus on the side delt doing the work

The "Pouring Water" Cue

A common cue is to rotate your hands as if pouring water from a pitcher at the top of the movement. While this does increase medial delt activation slightly, it can also cause shoulder impingement in some people.

Better approach: Keep a neutral or thumbs-slightly-up position. If pouring works for you without discomfort, use it. If it causes shoulder pinching, skip it.

Common Lateral Raise Mistakes

1. Going Too Heavy

The #1 mistake. Using too much weight forces momentum and reduces delt activation.

Fix: Use weight you can control through the entire range with good form. Ego has no place here—lateral raises are not a strength exercise.

2. Swinging the Weight

Using body momentum instead of shoulder muscle.

Fix: Stand still. If you need to swing, the weight is too heavy. Consider seated lateral raises to eliminate momentum.

3. Shrugging Shoulders

Traps taking over the movement.

Fix: Keep shoulders down and back. Think "long neck" throughout the movement.

4. Raising Too High

Going above shoulder level shifts emphasis to traps.

Fix: Stop when arms are parallel to floor, or just below.

5. Leading with Hands

Makes the movement feel like you're lifting to the front.

Fix: Lead with elbows. Imagine someone pulling your elbows up and out.

6. Straight Arms

Stresses the elbow joint unnecessarily.

Fix: Maintain a slight, fixed bend in elbows throughout.

7. Rushing Reps

Fast reps reduce time under tension.

Fix: Slow and controlled. 2 seconds up, 2-3 seconds down.

Lateral Raise Variations

Seated Lateral Raises

Eliminates lower body momentum.

How to do it:

1. Sit on bench with back supported
2. Dumbbells at sides
3. Same raising motion as standing
4. No swinging possible

Best for: Strict form, those who tend to cheat.

Cable Lateral Raises

Constant tension throughout the movement.

How to do it:

1. Stand sideways to low cable
2. Grab handle with far hand (crossing behind body) or near hand
3. Raise arm out to side
4. Same shoulder-height endpoint
5. Lower under control

Advantage: Tension at the bottom of the movement where dumbbells have none.

Leaning Lateral Raises

Increases range of motion and tension.

How to do it:

1. Hold pole or rack with one hand
2. Lean away at angle
3. Dumbbell hangs from far hand
4. Raise to shoulder height
5. The lean increases stretch at bottom

Best for: Greater range of motion, increased time under tension.

Machine Lateral Raises

Guided movement pattern.

How to do it:

1. Sit in lateral raise machine
2. Pad against upper arm or forearm
3. Raise against resistance
4. Lower under control

Advantage: Easy to maintain form, good for beginners or going to failure.

Behind-the-Back Cable Lateral Raises

Different angle of resistance.

How to do it:

1. Cable at low position, stand sideways
2. Grab handle from behind your body
3. Raise arm out to side
4. Cable provides unique resistance angle

Best for: Variety, hitting muscle from different angle.

Lying Lateral Raises

Eliminates all momentum.

How to do it:

1. Lie on side on incline bench
2. Hold dumbbell with top hand
3. Raise toward ceiling
4. Lower under control

Best for: Strict isolation, high reps.

Programming Lateral Raises

For Muscle Building (Hypertrophy)

• 3-4 sets of 12-20 reps
• Moderate to light weight
• Focus on squeeze and control
• 60-90 seconds rest

As a Finisher

• 2-3 sets of 15-25 reps
• Light weight
• Chase the burn and pump
• Minimal rest

In a Superset

Pairs well with:

• Front raises (anterior delt)
• Face pulls (rear delt)
• Overhead press (compound)

Weekly Frequency

• 2-4x per week
• Side delts recover quickly
• Can be trained frequently with moderate volume

Sample Shoulder Workout

Balanced Shoulder Day:

1. Overhead press: 4 x 6-8
2. Lateral raises: 4 x 12-15
3. Face pulls: 3 x 15
4. Front raises: 3 x 12

Side Delt Focus:

1. Lateral raises: 4 x 12
2. Cable lateral raises: 3 x 15
3. Machine lateral raises: 2 x 20
4. Overhead press: 3 x 8

Quick Add-On (any workout):

1. Lateral raises: 3 x 15-20

Tips for Maximum Side Delt Activation

Mind-Muscle Connection

Focus on feeling your side delt lift the weight. Don't just move dumbbells—feel the muscle work.

Pause at the Top

Hold the top position for 1 second. This eliminates momentum and increases time under tension.

Slow Negatives

Take 3 seconds to lower. The eccentric portion builds muscle too.

Use Partials

When you can't do full reps, continue with partial reps in the upper range to extend the set.

Drop Sets

Complete a set, immediately reduce weight, continue to failure. Excellent for side delts.

Keep Traps Out of It

Consciously keep shoulders down throughout. If traps take over, you're missing the point.

Light Weight, Big Gains

Lateral raises are not about lifting heavy. The side delt is a small muscle that responds to:

• Higher reps (12-20+)
• Perfect form
• Full range of motion
• Mind-muscle connection
• Frequency over intensity

Leave your ego at the door. The person doing strict lateral raises with 15 lb dumbbells will build better shoulders than the person swinging 40s.

Lateral Raises and Shoulder Health

Done correctly, lateral raises are joint-friendly. But issues can arise:

Potential problems:

• Impingement if raising too high or with excessive internal rotation
• Rotator cuff stress with bad form or too much weight
• Neck tension if traps constantly take over

Prevention:

• Stop at shoulder height
• Maintain neutral or thumbs-up position
• Use appropriate weight
• Include rotator cuff work in your routine

Common Questions

What weight should I use? Start light. If you can't do 12+ strict reps, it's too heavy. 10-25 lbs is normal for most people.

How high should I raise? To shoulder height (arms parallel to floor). Higher involves more trap.

Thumbs up or down? Neutral (thumbs forward) or slight thumbs-up is safest. Thumbs down can cause impingement.

Cables or dumbbells? Both have value. Dumbbells are hardest at the top; cables provide constant tension. Use both.

How often can I train side delts? 2-4x per week is fine. They're small muscles that recover quickly and respond to frequency.

Why don't my shoulders get wider? Usually not enough volume, too much weight with poor form, or not enough frequency. Sometimes genetics limit width, but most people can improve significantly.

The Bottom Line

Lateral raises are essential for building shoulder width. The key is using light enough weight to control the movement, leading with your elbows, and keeping your traps out of it.

Don't rush. Don't swing. Don't go too heavy. Strict reps with moderate weight and full range of motion will build the side delts you want.

Control the weight. Feel the muscle. Build wider shoulders.
