Lateral Raises: Proper Form, Muscles Worked & Variations

Lateral raises look simple: hold a weight in each hand and lift your arms out to the sides. Yet small changes in weight, elbow position, arm path, and momentum can completely change where you feel the exercise.

Done well, lateral raises provide direct training for the lateral, or middle, portion of the deltoid. That makes them particularly useful when the goal is stronger, more developed shoulders rather than simply moving the heaviest possible load.

Lateral raises are an isolation exercise in which you lift your arms away from your body against resistance, usually until the upper arms are around shoulder height. The movement primarily targets the lateral deltoids, while the anterior deltoids, trapezius, rotator cuff, and other shoulder-stabilizing muscles contribute to the movement. ACE Fitness

What Are Lateral Raises?

A lateral raise is a shoulder abduction exercise. Shoulder abduction simply means moving your upper arm away from the body’s midline.

The classic version uses a pair of dumbbells. You begin with your arms near your sides, maintain a slight bend in your elbows, and raise the weights outward until your arms are approximately parallel with the floor.

Unlike an overhead press, the lateral raise is primarily an isolation movement. You are not extending the elbows to press a weight overhead, so the triceps contribute far less than they do during pressing exercises.

Lateral raises can also be performed using:

• Cable machines
• Resistance bands
• Lateral raise machines
• Weight plates
• One dumbbell at a time
• Incline benches for supported variations

The equipment changes the resistance profile and stability demands, but the basic goal remains the same: load shoulder abduction with an emphasis on the lateral deltoid.

What Muscles Do Lateral Raises Work?

The lateral deltoid, commonly called the side delt or middle delt, is the main muscle people are trying to train with lateral raises.

Research comparing several shoulder-raise variations has found substantial medial-deltoid activation during lateral raises. In one study involving competitive bodybuilders, the neutral-grip lateral raise produced greater medial-deltoid EMG activity than several other tested raise variations and the frontal raise. PubMed

Lateral deltoid

The deltoid is the large muscle covering the shoulder joint and is commonly divided into three functional portions:

The lateral portion is particularly important for the visual width of the shoulders.

That is one reason lateral raises are common in bodybuilding and hypertrophy programs.

Supraspinatus and rotator cuff

The supraspinatus is one of the four rotator cuff muscles. It contributes to shoulder elevation and works alongside the deltoid during arm raising.

The remaining rotator cuff muscles—subscapularis, infraspinatus, and teres minor—also play important roles in controlling and stabilizing the humeral head as your arm moves.

Biomechanical research shows that the contribution and mechanical advantage of shoulder muscles change throughout the elevation arc rather than remaining constant from the bottom to the top. PubMed

Trapezius

Your trapezius also participates.

As the arm rises, the scapula must move appropriately. The upper and lower trapezius, together with the serratus anterior, contribute to scapular movement and stability.

Some trap involvement is therefore normal.

The problem occurs when you use excessive weight and turn the exercise into an exaggerated shrug. In that situation, the movement may no longer provide the lateral-delt emphasis you intended.

Serratus anterior

The serratus anterior helps control and upwardly rotate the scapula as the arm elevates.

You may not feel it working like the deltoid, but coordinated scapular movement is part of normal overhead and arm-elevation mechanics.

How to Do Lateral Raises Correctly

The dumbbell lateral raise is the easiest version to learn because it requires only two dumbbells and enough room to raise your arms.

The American Council on Exercise recommends a neutral grip, a stable torso, controlled elevation of the dumbbells, and raising the arms to approximately shoulder level. ACE Fitness

Step 1: Choose light dumbbells

Start lighter than you think you need.

The lateral raise puts the weight relatively far from your shoulder joint, creating substantial leverage even with modest dumbbells.

A weight that seems light during a curl can feel surprisingly demanding during a strict lateral raise.

Step 2: Establish your starting position

Stand upright with your feet roughly hip- to shoulder-width apart.

Hold one dumbbell in each hand.

Keep:

• Chest comfortably upright
• Core braced
• Wrists neutral
• Elbows slightly bent
• Head aligned with your torso

Avoid aggressively pinning your shoulder blades together. Your scapulae need to move naturally as your arms elevate.

Step 3: Raise your arms outward

Lift your arms away from your body while maintaining the same gentle elbow bend.

Think about moving your upper arms, rather than simply throwing your hands upward.

Your arms can travel slightly forward rather than forming a perfectly straight line directly out from your torso.

Step 4: Stop around shoulder height

For the conventional dumbbell variation, raise your upper arms to approximately shoulder height.

Your arms should end roughly parallel with the floor.

ACE’s exercise guidance similarly describes lifting until the arms are level with the shoulders while maintaining an upright torso and neutral wrists. ACE Fitness

Step 5: Lower slowly

Don’t let gravity finish the repetition.

Control the dumbbells as you return to the starting position.

The lowering, or eccentric, phase is still part of the exercise.

Step 6: Repeat without resetting your entire posture

Once the weights reach the bottom, begin your next repetition while keeping your torso controlled.

A good set should look repetitive and predictable.

If every repetition requires a larger swing, hip drive, or lean, the load is probably too heavy for the technique you’re trying to maintain.

Lateral Raise Form: The Details That Matter

There isn’t one millimeter-perfect lateral raise technique that everyone must copy. Shoulder anatomy, limb length, training experience, and individual comfort can affect the most natural movement path.

Several principles, however, are consistently useful.

Keep a slight bend in your elbows

Completely locking your elbows creates a longer lever.

A gentle bend usually makes the movement easier to control without fundamentally changing its purpose.

Keep that elbow angle relatively consistent throughout the repetition.

If you start bending your elbows dramatically as the dumbbells rise, you are changing the movement to make the load easier.

Don’t force the arms directly sideways

Many lifters feel more comfortable raising their arms slightly forward of a perfectly straight lateral line.

This places the upper arm closer to the scapular plane, which generally corresponds more naturally with the orientation of the shoulder blade.

Your body should resemble a wide “V” when viewed from above rather than necessarily forming a rigid “T.”

Keep your wrists neutral

Don’t bend your wrists simply to make the dumbbells appear higher.

Your hands, wrists, and forearms should remain comfortably aligned.

Don’t deliberately pour the dumbbells downward

An old bodybuilding cue tells lifters to imagine “pouring a pitcher” at the top of a lateral raise.

That means internally rotating the shoulder so the little-finger side of the hand rises higher.

This isn’t necessary for training the lateral deltoid.

An EMG study comparing different lateral-raise positions found that changing humeral rotation alters recruitment across the deltoid, upper trapezius, and other muscles. A neutral variation produced strong medial-deltoid activity without requiring exaggerated internal rotation. PubMed

A neutral, comfortable hand position is a sensible default.

Why Do Lateral Raises Feel So Difficult?

Many people can shoulder press relatively heavy dumbbells but struggle with a fraction of that weight during lateral raises.

That’s normal.

The difference comes partly from leverage.

During a lateral raise, the dumbbell moves farther away from the shoulder joint. As your arm approaches horizontal, the resistance creates a large external moment around the shoulder.

This explains two characteristics of dumbbell lateral raises:

The bottom feels relatively easy. When your arm hangs near your side, gravity produces relatively little rotational demand around the shoulder.

The top feels much harder. As the arm approaches horizontal, the dumbbell has a much larger moment arm relative to the shoulder.

That changing resistance curve is one of the biggest differences between dumbbell and cable lateral raises.

Common Lateral Raise Mistakes

Technique usually breaks down because someone is trying to make the exercise heavier rather than making the target muscles work harder.

Using too much weight

This is probably the most common error.

You grab heavy dumbbells, bend your knees, swing your torso, throw the weights upward, and let them fall.

The dumbbells moved—but your deltoids didn’t necessarily receive better training.

Choose a load you can control through the intended range.

Swinging your torso

A little natural body movement isn’t automatically disastrous, particularly during the final repetitions of a hard set.

Repeatedly generating momentum from the hips, however, changes the exercise.

If your torso rocks backward every time the weights rise, reduce the load.

Shrugging excessively

Some trapezius involvement is normal because the shoulder blades participate in arm elevation.

But deliberately shrugging the shoulders toward your ears can shift the character of the exercise.

Think about raising your upper arms rather than trying to lift your shoulders.

Raising the weights too quickly

Fast repetitions make it easier to use momentum.

Try a smooth lifting phase followed by a controlled lowering phase.

You don’t need an artificially slow tempo. You simply need enough control that you’re moving the weights rather than throwing them.

Dropping the dumbbells

The repetition isn’t finished when you reach the top.

Control the descent.

Research examining lateral-raise variations has observed muscle activity during both concentric and eccentric phases, reinforcing that both portions are legitimate parts of the movement. PMC

Turning it into a front raise

If your hands travel too far forward, the exercise gradually becomes more like a front raise.

That increases the emphasis on the anterior deltoid.

A frontal raise has been shown to produce considerably more anterior-deltoid activity than several lateral-raise variations. PubMed

A small forward angle is fine; lifting straight forward is a different exercise.

How Heavy Should You Go on Lateral Raises?

There is no universal “good” lateral raise weight.

A useful load is one that challenges your shoulders while allowing you to maintain your chosen technique.

That could mean very light dumbbells for one person and considerably heavier weights for an experienced lifter.

Instead of comparing dumbbell numbers, ask:

Can I control the weight without swinging?

Can I maintain a consistent elbow position?

Can I lower the dumbbells under control?

Am I actually challenging my shoulders?

If the answer is yes, the load is probably appropriate.

If you need momentum from the first few repetitions, it is likely too heavy for strict lateral raises.

Lateral Raises Sets and Reps

Lateral raises are usually better suited to moderate and higher repetition ranges than maximal-strength training.

You don’t need to perform three-rep lateral raises simply because low repetitions work well for exercises such as squats or bench presses.

For general muscle-building work, a practical starting point is:

These aren’t rigid rules.

Muscle growth can occur across different loading ranges when sets provide sufficient effort and overall training is appropriately programmed.

The broader resistance-training evidence also emphasizes total training volume and consistency rather than one magical repetition range. The 2026 American College of Sports Medicine position stand recommends tailoring load and volume to the goal and notes that hypertrophy benefits from higher weekly training volume. ACSM

How close to failure should you train?

You don’t have to reach absolute muscular failure on every set.

The 2026 ACSM review reports that training to momentary muscle failure is not consistently necessary for outcomes in average healthy adults. ACSM

For practical lateral-raise training, finish many sets when you feel you have only a few technically sound repetitions remaining.

As you gain experience, you can occasionally take isolation exercises closer to failure while still maintaining reasonable control.

How Often Should You Do Lateral Raises?

For many people, training the shoulders more than once per week works well.

ACSM’s updated resistance-training guidance emphasizes training major muscle groups at least twice weekly as part of a consistent program. ACSM

However, frequency and weekly volume are related.

If you’re performing a large amount of shoulder work during each session, you may need more recovery. If each session contains only a few lateral-raise sets, distributing those sets across multiple days may be comfortable.

Remember that your deltoids also receive work during:

• Overhead presses
• Bench presses
• Incline presses
• Rows
• Rear-delt exercises

Your program should therefore consider total shoulder training, not lateral raises in isolation.

Dumbbell Lateral Raises vs Cable Lateral Raises

Both variations train shoulder abduction, but they don’t feel identical.

Dumbbell lateral raises

Dumbbells are inexpensive, accessible, and easy to progress.

Their main characteristic is a highly variable resistance curve.

The exercise is relatively unloaded near the bottom because gravity is pulling almost parallel to the arm. The challenge rises considerably as the arm approaches horizontal.

Cable lateral raises

A cable can maintain meaningful resistance earlier in the movement because the cable pulls from the side rather than straight down.

ACE’s single-arm cable lateral raise uses a waist-height pulley and instructs the lifter to raise the arm until it is parallel with the floor before slowly lowering it. ACE Fitness

Neither is universally superior.

You can use whichever allows comfortable, progressive training—or include both.

Best Lateral Raise Variations

Changing the equipment or body position can make lateral raises easier to perform, harder to cheat, or simply more comfortable.

Dumbbell lateral raise

This is the standard version and the best starting point for most people.

Stand upright, raise the dumbbells outward, and lower them under control.

It requires minimal equipment and teaches the fundamental movement.

Single-arm cable lateral raise

Using one arm at a time allows you to focus on each shoulder independently.

It also makes it easier to adjust your body position relative to the resistance.

Cable resistance remains present at positions where a dumbbell may provide relatively little challenge.

Machine lateral raise

A lateral raise machine provides a fixed movement path and removes much of the balance requirement.

ACE’s machine variation uses pads positioned above the elbows, with the lifter raising the upper arms before slowly returning to the starting position. ACE Fitness

Machines can be especially useful when you want to train close to fatigue without worrying about stabilizing two dumbbells.

Seated lateral raise

Sitting reduces your ability to generate momentum from your lower body.

That makes the seated version useful if you repeatedly turn standing lateral raises into full-body swings.

Expect to use less weight.

Leaning cable lateral raise

Holding a stable structure and leaning slightly away from a low cable changes the relationship between your arm and the cable.

This can make the exercise feel different through the lower and middle portions of the range.

It is useful as a variation rather than a mandatory upgrade.

Resistance-band lateral raise

Stand on a resistance band and hold an end in each hand.

The resistance increases as the band stretches, making the upper portion progressively harder.

Bands are convenient for home workouts and travel.

Lateral Raises vs Shoulder Press

These exercises shouldn’t necessarily compete for a place in your workout because they serve different purposes.

The shoulder press is a compound movement involving the shoulder and elbow joints. The anterior deltoids and triceps contribute substantially, while the lateral deltoids also participate.

The lateral raise is much more focused on shoulder abduction.

Research comparing common upper-body exercises has found strong medial-deltoid activity during both shoulder presses and lateral raises, while the exercises create different overall muscular demands. PMC

For balanced programming, they can complement each other.

Lateral Raises vs Front Raises

The key difference is direction.

With lateral raises, the arms primarily travel outward.

With front raises, they travel forward.

That seemingly small difference changes which part of the deltoid receives greater emphasis.

Research comparing the movements found greater anterior-deltoid activation during the frontal raise, while lateral-raise variations produced greater emphasis on the medial deltoid. PubMed

If your program already includes bench presses, incline presses, and overhead presses, your anterior deltoids may already receive considerable training.

Direct lateral-delt work can therefore fill a different role.

Should You Do Lateral Raises Before or After Shoulder Presses?

For most general hypertrophy programs, lateral raises fit naturally after compound pressing exercises.

A typical sequence might be:

1. Overhead press
2. Chest or upper-body compound exercise
3. Lateral raises
4. Rear-delt exercise
5. Additional accessory work

This lets you perform your heavier compound exercise while fresh and then directly train the lateral deltoids afterward.

There are exceptions.

If lateral-delt development is your highest training priority, performing lateral raises earlier may allow you to give them more effort.

Exercise order should reflect your priorities rather than an arbitrary gym rule.

How to Progress Lateral Raises

Progress isn’t limited to grabbing a heavier dumbbell every week.

Dumbbell jumps can be surprisingly large relative to the loads used for lateral raises. Moving from 10-pound to 15-pound dumbbells, for example, represents a 50% increase.

Instead, progress gradually.

Suppose you perform:

3 sets of 10–15 repetitions.

You might begin with:

• Set 1: 13 reps
• Set 2: 11 reps
• Set 3: 10 reps

Over subsequent sessions, try to accumulate more good repetitions.

Eventually you may reach:

• Set 1: 15 reps
• Set 2: 15 reps
• Set 3: 15 reps

Then increase the resistance slightly and rebuild your repetitions.

You can also progress by improving control, expanding a comfortable range of motion, or adding appropriate weekly volume.

The goal is progressive overload without sacrificing the movement you’re trying to train.

Why You Feel Lateral Raises in Your Traps

Feeling your trapezius during lateral raises does not automatically mean you’re performing them incorrectly.

Your scapula must participate when you raise your arm, and the trapezius contributes to scapular movement.

But if your traps dominate every repetition, check three things.

First, reduce the weight.

Second, stop consciously shrugging the dumbbells upward.

Third, concentrate on moving your upper arms outward while keeping your torso relatively still.

Internal shoulder rotation may also alter muscle recruitment. In the EMG study of competitive bodybuilders, internally rotated lateral raises produced greater upper-trapezius activity than several other tested variations. PubMed

Why Don’t You Feel Lateral Raises in Your Side Delts?

A lack of burning or soreness doesn’t prove an exercise isn’t working.

However, if you consistently feel lateral raises everywhere except your shoulders, technique may be worth reviewing.

Try:

Reducing the weight. Heavy weights often encourage momentum.

Slowing the lowering phase. Don’t allow the dumbbells to fall.

Keeping the elbows consistent. Avoid turning the movement into an upright row.

Using cables or a machine. Different resistance profiles sometimes make it easier to identify the target movement.

Performing one arm at a time. This lets you focus on positioning and control.

Muscle sensation can be useful feedback, but progression and consistent technique matter more than chasing an intense “burn.”

Can Lateral Raises Build Bigger Shoulders?

Yes, lateral raises can contribute to shoulder hypertrophy when they are combined with sufficient training effort, volume, recovery, and nutrition.

They are especially useful because they directly train the lateral deltoid.

But one exercise does not build a complete shoulder.

A well-rounded program typically includes movements covering different functions of the deltoid and shoulder complex, such as:

• Overhead pressing
• Lateral raises
• Rear-delt work
• Rows
• Appropriate rotator-cuff work

ACE’s 2026 evidence-based shoulder-training guidance similarly emphasizes combining exercises that address the different portions and functions of the deltoids rather than relying on a single movement. ACE Fitness

Are Lateral Raises Safe for Your Shoulders?

For healthy adults, lateral raises can be a normal resistance-training exercise when performed with an appropriate load and comfortable technique.

Pain, however, shouldn’t be treated as something you must push through.

If lateral raises produce sharp, persistent, or worsening shoulder pain, stop the exercise and determine why.

Potential modifications include:

• Reducing the load
• Using a smaller comfortable range of motion
• Moving the arms slightly forward
• Trying a cable or machine
• Using a neutral grip
• Training one arm at a time

ACE’s dumbbell lateral-raise instructions also describe slight external rotation as the arms approach shoulder level rather than maintaining pronounced internal rotation throughout the lift. ACE Fitness

Anyone recovering from a shoulder injury, surgery, rotator cuff problem, or other diagnosed shoulder condition should follow guidance from an appropriate healthcare or rehabilitation professional rather than relying on generic exercise instructions.

A Simple Lateral Raise Workout

You don’t need a complicated shoulder routine to make the exercise productive.

A straightforward hypertrophy-focused session could include:

Overhead press: 3 sets
Dumbbell lateral raises: 3 sets of 10–15 reps
Cable lateral raises: 2–3 sets of 12–20 reps
Rear-delt exercise: 3 sets of 12–20 reps

This is only an example rather than a universal prescription.

Your ideal volume depends on how frequently you train, what other pressing and pulling exercises you perform, your experience, recovery, and training goals.

ACSM’s 2026 resistance-training recommendations emphasize this individualization and note that consistency is more important than unnecessarily complex programming. ACSM

How to Get More From Lateral Raises

Lateral raises don’t reward ego lifting particularly well.

They reward repeatable technique.

Use enough resistance to challenge your shoulders, but not so much that every repetition becomes a swing. Keep a comfortable bend in the elbows, let the arms travel through a natural path, raise them to roughly shoulder height, and control the return.

Dumbbells are an excellent starting point, while cables and machines provide useful alternatives when you want a different resistance profile or greater stability.

Most importantly, treat lateral raises as what they are: a focused shoulder isolation exercise. Combine them with progressive resistance training, adequate recovery, and other complementary upper-body movements, and they can be an effective tool for developing stronger, more muscular shoulders.
