You’ve probably spent hours hammering away at overhead presses, hoping your T-shirts will start fitting better. It makes sense, right? If you want big shoulders, you lift heavy stuff over your head. But for a lot of guys—and girls—that heavy pressing just ends up building thick triceps and a sore lower back while those "cannonball" delts stay stubbornly flat. Getting broader is actually a game of geometry, not just raw power.
The truth is that how to get broader shoulders isn't about your total strength on a bench press. It’s about the lateral head of the deltoid. That’s the middle bit of the muscle that literally pushes your silhouette outward. If you ignore that specific sliver of muscle, you’ll look thick from the side but narrow from the front.
Honestly, most people train shoulders like they’re trying to move a fridge. They use momentum, they shrug their traps to their ears, and they wonder why their frame hasn't widened an inch in six months. We need to talk about why that happens and how to actually fix the "narrow" look without wrecking your rotator cuffs.
The Science of the "V-Taper" and Medial Delts
If we look at the anatomy, the shoulder is a three-headed beast: the anterior (front), lateral (side), and posterior (rear) deltoids. Most of us have overdeveloped front delts because they help out with every single chest press or push-up you’ve ever done.
To look wide, you need to prioritize the lateral deltoid. This muscle doesn't respond well to ego lifting. Studies by researchers like Dr. Bret Contreras have shown that the lateral deltoid is most active when the arm is moved away from the body in the frontal plane. This is why the lateral raise is the king of width, even though it feels "lighter" than a heavy press.
But here’s the kicker. Most people do lateral raises wrong. They swing the weights. They use their upper traps to yank the weight up. When your traps take over, your shoulders stop growing. You’re basically training to have a thick neck, not wide shoulders. You have to keep the scapula depressed. Think about pushing the dumbbells out toward the walls, not up toward the ceiling.

Stop Obsessing Over the Overhead Press
Don't get me wrong. The Military Press is a legendary lift. It builds massive overall force production. But if your goal is purely aesthetic width, it’s often overrated. Why? Because as you press upward, the front deltoid takes the lion's share of the load.
The lateral delt—the one that makes you broad—is only a secondary mover in a vertical press. If you want to know how to get broader shoulders, you have to stop treating the press as your only "main" lift.
Try switching your focus to "high-volume isolation." The lateral deltoid is composed of a mix of fiber types, but many lifters find they respond best to higher rep ranges, think 15 to 25 reps. This creates the metabolic stress and "pump" that triggers sarcoplasmic hypertrophy. Heavy weights are for bones; high tension is for round shoulders.
The Rear Delt Secret
Narrow shoulders often look that way because they’re slumped forward. This is usually due to "computer posture" and overdeveloped chest muscles. If your rear delts are weak, your shoulders roll inward, making you look like a caveman.
Training the posterior deltoid (the back of the shoulder) pulls the humerus back into its socket. It creates a 3D effect. When someone looks at you from an angle, the rear delt provides that "shelf" look. Exercises like face pulls or reverse cable flies are non-negotiable. If you aren't doing them twice a week, you're leaving width on the table.
Mechanical Tension vs. Mind-Muscle Connection
It sounds like "bro-science," but the mind-muscle connection is actually backed by EMG data. If you can't feel your side delts working during a movement, they probably aren't.
Try this: stand with your arms at your sides. Without holding any weight, raise your arms to a "T" position. Stop when your hands are level with your shoulders. Now, squeeze. Feel that burn on the very tip of your shoulder? That is the target. If you feel it in your neck, your traps are stealing the gains.
You’ve got to be disciplined. Drop the weights. Most men should be doing side raises with 15 or 20-pound dumbbells, not 50s. If you’re swinging, you’re failing.
Specific Movements That Actually Work
Let's get into the weeds. Not all exercises are created equal for width.
1. Cable Lateral Raises (Behind the Back)
Cables are superior to dumbbells for one reason: constant tension. With a dumbbell, there is zero tension at the bottom of the movement. With a cable, the muscle is under load for the entire range of motion. Doing them behind your back forces a slightly different recruitment pattern that hits the lateral head hard.
2. The Lu Raise
Named after Chinese weightlifter Lu Xiaojun, this involves taking a light weight and raising it in a full arc until your hands meet above your head. It’s a massive range of motion. It forces the entire shoulder complex to stabilize. It’s brutal.
3. Wide-Grip Upright Rows
Be careful with these. A close grip can wreck your wrists and shoulders. But a wide grip—hands outside shoulder width—is a secret weapon for width. Keep the bar close to your body and pull with your elbows. Stop at chest height. Don't go to your chin.
4. Face Pulls with an External Rotation
When you pull the rope toward your forehead, don't just pull back. Try to "tear the rope apart" and rotate your thumbs toward the wall behind you. This hits the rear delts and the rotator cuff. A healthy shoulder is a shoulder that can grow.
Nutrition and the "Illusion" of Width
You can’t build muscle out of thin air. To get broader, you need a slight caloric surplus. You need protein—about 0.8 to 1 gram per pound of body weight. But there’s a trick.
Broadness is a ratio. It’s the ratio of your shoulders to your waist. If you have a "dad bod" or carry a lot of belly fat, your shoulders will always look narrow, no matter how much you lift. This is why bodybuilders focus so much on a tight midsection.
Sometimes, the fastest way to look like you have broader shoulders is actually to lose five pounds of fat from your waist. It creates an optical illusion. The wider the V, the more impressive the frame.
The Frequency Trap
Most people train shoulders once a week on "Shoulder Day." That’s usually not enough for a stubborn muscle group. The deltoids recover relatively quickly compared to the hamstrings or the back.

Try hitting your side delts 3 times a week. You don't need a full workout every time. Just add 3 or 4 sets of lateral raises at the end of your other workouts. This increased frequency keeps protein synthesis spiked in those specific fibers.
Real-World Examples: The "Otter" vs. The "Fridge"
Look at swimmers. They have notoriously broad shoulders. Why? Is it because they lift heavy? Not really. It’s because of the constant, repetitive lateral movement of the arms against resistance (water). They are essentially doing thousands of lateral raises every single day.
Compare that to a powerlifter who only does heavy overhead presses. They might have more "thickness," but the swimmer often looks "broader" in a t-shirt. We want to bridge that gap. We want the power of the press with the frequency and isolation of the swimmer's movement.
Avoiding Injury
Nothing kills progress like a labrum tear or impingement. Your shoulders are the most mobile joints in your body, which also makes them the most fragile.
- Warm up: Use light bands.
- Avoid "Internal Rotation" under heavy loads: If an exercise makes your shoulder feel like it's pinching, stop.
- Balance your pushes and pulls: For every set of pressing you do, do two sets of pulling (rows, face pulls).
Summary of Actionable Steps
Getting wide isn't about luck. It's about targeting the right spots with enough volume to force growth. Here is how you actually execute this:
- Prioritize Lateral Raises: Move these to the beginning of your workout when you have the most energy. Use cables whenever possible for constant tension.
- Lighten the Load: If you can’t hold the weight at the top of a lateral raise for a one-second pause, it’s too heavy. Stop ego-lifting.
- Hit the Rear Delts Twice a Week: Use high reps (15-20) to pull your posture back and create that 3D roundness.
- Increase Frequency: Train the side delts 3 times a week. Small doses of high-quality volume are better than one massive, exhausting session.
- Clean Up the Diet: Shrink the waist to make the shoulders pop. A 32-inch waist makes 20-inch shoulders look massive; a 40-inch waist makes them look average.
- Mind the Traps: Keep your neck relaxed. If you find yourself shrugging, you're turning a shoulder exercise into a trap exercise.
Consistency is boring, but it’s the only thing that works. You won't wake up tomorrow with a superhero frame. But if you spend the next twelve weeks focusing on the lateral head and keeping your form surgical, your shirts are going to start feeling very tight in all the right places.
