Cable Lateral Raises vs Dumbbell: Which Is Better for Growth?

Cable lateral raises and dumbbell lateral raises train the same main muscle, the lateral deltoid, but anyone who has tried both knows they don’t feel quite the same.

With dumbbells, the first part of the raise is relatively easy, then the exercise gets harder as your arm moves away from your body. A cable can load the shoulder earlier in the movement, depending on where the pulley is set and where you stand.

It’s easy to assume that makes cables better for building your side delts. The research so far tells a more balanced story.

A 2025 study directly compared the two exercises and found similar lateral-delt growth after eight weeks. So instead of asking which one wins, it’s more useful to look at how each version loads the shoulder, and which one fits your training better.

Cable vs dumbbell lateral raises: quick comparison

Why do cable and dumbbell lateral raises feel so different?

You’ll often hear that cables provide constant tension. That’s part of the picture, but it doesn’t explain everything.

A dumbbell is always pulled straight down by gravity. When your arm hangs close to your side, the weight is also close to the shoulder joint, so the torque at the shoulder is relatively low. As your arm rises, the leverage changes and the raise becomes harder.

This is often described as an ascending resistance profile: the movement becomes more demanding as your arm moves farther from your body.

A cable lets you change the direction of resistance. With a low pulley and the right body position, the shoulder can already be working hard near the start of the raise. That creates more of a descending resistance profile, with more resistance while the delt is in a lengthened position.

In practice, that’s why a cable lateral raise can feel “on” almost immediately, while the bottom of a dumbbell raise often feels much easier.

The mechanical difference is real. The bigger question is whether it produces more muscle growth.

Do cable lateral raises build more muscle than dumbbells?

So far, there’s no clear evidence that they do.

A 2025 study published in Frontiers in Physiology followed 24 resistance-trained men and women for eight weeks. Each participant trained one arm with cable lateral raises and the other with dumbbell lateral raises. Range of motion and other variables were matched, and participants trained twice a week with sets taken to momentary failure.

By the end of the study, lateral-delt muscle thickness had increased in both conditions, by roughly 3.3% to 4.6%. The researchers found no clear hypertrophy advantage for either version.

That’s worth noting because cable lateral raises look appealing on paper: they can load the delt more in a lengthened position, which has received plenty of attention in hypertrophy research. But in this direct comparison, that mechanical advantage didn’t translate into clearly greater growth.

Keep two limits in mind. The study lasted just eight weeks, which is useful for short-term changes but not long enough to tell whether one variation pulls ahead over months or years. The participants were also experienced lifters, so results may differ in beginners.

For now, the study shows that both versions can work well over an eight-week block. It doesn’t prove their long-term results will always be identical.

Why do cable lateral raises often feel harder?

This catches a lot of people out.

You switch from a 7 kg dumbbell to what looks like a lighter cable setting, start your first set, and somehow the cable feels harder.

That doesn’t mean you suddenly got weaker. The numbers simply aren’t directly comparable.

Cable resistance depends on the machine, pulley setup, cable angle and your position relative to it. You may also be dealing with meaningful resistance much earlier in the rep, instead of the relatively easy start you get with a dumbbell.

So there’s little value in trying to match your dumbbell weight when you switch to cables. Pick a resistance that lets you control the movement cleanly and build from there.

Lateral raises are also one of those exercises where small jumps aren’t actually small. Going from a 6 kg dumbbell to an 8 kg dumbbell is a 33% increase.

If that jump turns a lateral raise into a full-body swing, progression doesn’t have to mean adding weight straight away. An extra rep or two, cleaner technique, better control through the range of motion or a smaller load increase can all move the exercise forward.

What a 30-day shoulder challenge added to the comparison

A recent YouTube challenge from Browney, a fitness creator with more than 12 million subscribers, offered a more everyday look at the same question.

In “5 Guys Train Shoulders Every Day, This Is What Happened,” published in August 2026, Browney invited four other participants, including his dad, to spend 30 days trying different approaches to shoulder training.

Across the challenge, lateral raises were done with dumbbells, resistance bands, cables and even improvised heavy objects when regular equipment wasn’t available.

By the later stages, after training lateral raises with several forms of resistance, Browney returned to cable lateral raises and said he preferred them for the constant tension and the stretch at the bottom of the rep.

He also noticed something practical while using the Speediance cable system: even when he moved quickly, the cable stayed under tension rather than going slack.

That fits the resistance-profile difference above. The research suggests both versions can produce similar short-term growth, but they don’t necessarily feel interchangeable in a workout.

For some lifters, the continuous resistance of a cable simply feels better. Others prefer the simplicity of picking up two dumbbells and getting to work.

Cable or dumbbell lateral raises: which should you use?

If you want the simplest setup, want to train both arms together, or simply prefer free weights, dumbbell lateral raises are a solid choice.

If you prefer resistance earlier in the movement and train at home, a smart cable system like Gym Monster 2 gives you that cable feel, with small, precise load increments, without a full-size cable machine.

You don’t have to choose one forever. Cables one day and dumbbells another is perfectly reasonable.

The research gives you freedom here: both can grow your side delts. The rest comes down to which version you can perform well, progress over time and actually enjoy.

FAQs

Are cable lateral raises better than dumbbells for muscle growth?

Current direct evidence doesn’t show a clear advantage. In an eight-week study of trained lifters, both produced comparable increases in lateral-delt thickness.

Why can I use less weight on cable lateral raises?

The resistance isn’t directly comparable. Pulley setup, cable angle and resistance earlier in the movement can make a lighter cable setting feel harder than the same number on a dumbbell.

Should I do both cable and dumbbell lateral raises?

You can, but you don’t have to. Both train the lateral delts effectively. Rotating them between sessions or training blocks is an easy way to use each without overcomplicating your program.
