We’ve already written an article about how skinny guys can build broader shoulders over on Bony to Beastly, including a bunch of neat information about genetics, aesthetics, and hypertrophy training in general.

In this article, I want to talk about how a more intermediate lifter can build broader, wider shoulders. Lifters often have a fairly easy time building bigger front delts from bench pressing and overhead pressing, but it’s common for guys to have trouble building bigger side delts, which is what will make their shoulders broader, giving them a greater shoulder-to-waist ratio.

So in this article, let’s talk about the three best lifts for building bigger side delts and how to get the most growth out of them.

Before/after illustration of a man building broader shoulders and bigger side delts.

Introduction

There are quite a few lifts that work our shoulders, ranging from the close-grip bench press (for our front delts) to the chin-up (for our rear delts). And that’s great, but these lifts help us build bigger shoulders, not necessarily broader shoulders.

If we’re talking specifically about building broader, wider shoulders, then we’re talking about the side delts, and there are only a few lifts that work the side delts:

  • The Overhead Press (Main Compound Lift)
  • The Upright Row (Secondary Assistance Lift)
  • The Lateral Raise (Tertiary Accessory Lift)

There are several variations of each lift, and each has some nuance to it. Furthermore, the shoulders are a tricky joint, and not everyone will be able to perform all three movements without aggravating their shoulders (i.e. shoulder impingement). So we don’t necessarily want to use all three. Not yet, anyway. Rather, we want to find the best lifts for you as an individual.

The good news is that our shoulders have tremendous potential for growth, and of all your measurements, your shoulder circumference will likely see the biggest improvement as you bulk up. In my own case, I went from having 39″ shoulders to 52″ shoulders.

The Overhead Press

The overhead press is done by pressing a weight vertically overhead. It can be done from a standing or seated position with either dumbbells or a barbell (or even a kettlebell or log). The standing variations tend to be best for our spines and torsos, but for building broader shoulders, all variations are great.

The overhead press is the big compound lift that’s dedicated to bulking up the fronts and sides of our shoulders, along with our upper chests, upper traps, and serratus anterior muscles.

As you can see, it’s a big lift that engages a ton of overall muscle mass. The fact that it bulks up our upper chests, shoulders, and traps makes it a great lift for improving the muscularity of our entire shoulder girdle, making it perhaps the single best lift for improving our appearance. It also, of course, trains our side delts. It will help us build broader shoulders.

Picking the Best Variation

The catch with the overhead press is that it requires quite a strong core and quite a lot of shoulder mobility to press a weight overhead without arching in the lower back and letting the ribs drift up. When that happens, especially if you’re lifting a heavy barbell, it raises the risk of hurting the lower back. It’s quite a safe lift when done correctly, but not everyone can do it correctly. At least not right away.

If you’re having trouble doing the standing overhead press, you could do them seated, but that can actually put more pressure on our spines—specifically the tail bone—since the load isn’t being buffered by our lower bodies anymore. Still, some people find that it helps.

A better solution, we’ve found, is to use the half-kneeling dumbbell overhead press. We can stimulate a similar amount of growth in our shoulders, but the load is much lighter, reducing the risk of hurting our lower back. The kneeling split-stance also makes it easier to do the lift with good posture. After a bit of practice, most people can then shift to doing the standing overhead press—again, using just a single dumbbell at a time.

When dumbbell overhead pressing becomes easy, you can progress to the barbell. Or not. Dumbbells are just as good. It’s entirely up to you.

Hypertrophy Rep Range

In general, anywhere from 4–40 reps can be good for hypertrophy training, with 5–30 reps being slightly more practical, and 6–20 reps being the easiest of all.

More specifically, the barbell overhead press is a big compound lift that suits heavier sets of 5–10 reps. Interestingly, though, many people find that going above ten reps is easier on their front delts and traps but harder on their lateral delts, which in this case, is exactly what we want. This gives us a few options:

  • 3–5 sets of 5–10 reps: to treat the overhead press as a big compound lift that bulks up our shoulder girdle overall. Afterwards, we can focus specifically on our side delts with upright rows and lateral raises.
  • 2–4 sets of 10–15 reps: use the overhead press as a lighter lift that emphasizes our side delts. And if you’re already doing the bench press, especially with a closer grip, then your front delts will be taken care of anyways.
  • Three pyramid sets of 5, 8, and 12 reps: if you use pyramid sets, doing a heavy set followed by progressively lighter sets, you can get the best of both worlds. It won’t necessarily yield more overall growth, but it may yield more balanced muscle growth. This will also let you see which rep range you prefer.

If you’re using dumbbells, slightly lighter sets of 8–15 reps tend to work better. That way you aren’t wasting too much effort swinging the weights into position and balancing them as you press them upwards.

The Upright Row

Upright rows are a great compound accessory lift is one of the very best lifts for building broader shoulders and for improving our overall aesthetics. However, they’re also finicky and surprisingly controversial, with some people finding them uncomfortable and the more fearful experts advising against ever doing them.

The upright row works the forearms, upper arms (elbow flexors), upper back (traps), and shoulders (side and rear delts). The limiting factor is often our side delts or traps, and so they tend to get the best growth stimulus.

Even just looking at this image, it’s easy to see why many bodybuilders swear by the upright row for improving the aesthetics of their physiques. But it’s also an atypical movement pattern, and some of the more cautious lifters worry that it might hurt their shoulders.

Are Upright Rows Dangerous?

Upright rows are infamous for causing pain and inflammation in our shoulder joints (shoulder impingement), especially when we try to force a technique that doesn’t feel natural. However, these issues rarely sneak up on us. Rather, it’s like water torture, where repetitively doing a lift that’s slightly painful cause damage to accumulate.

If upright rows grind your shoulder joints or cause sharp pain, you can either adjust your technique or stop doing them, preventing the inflammation from ever progressing into a problem.

But if upright rows don’t hurt your shoulders, then there’s no reason to think they’re doing any damage. In fact, our bodies adapt to weight training by growing both stronger and tougher, and that includes our muscles as well as our joints and connective tissues. If we can find a way to do upright rows in a way that feels good, that area should grow more robust.

Min-Maxing Technique

All of our shoulder joints are a little different, and so there’s no single correct way to do upright rows. Start with a shoulder-width grip, but experiment going both narrower and wider. Pull as high as you can comfortably pull, focusing on raising your elbows out to the sides, but stop before you feel any grinding in your shoulder joints. Some people can only bring the barbell to shoulder height, and that’s fine, but many people can go a bit higher. With a bit of experimentation, most of us can find a way to make upright rows feel great on our shoulder joints and muscles.

Since everyone benefits from slightly different grip widths and ranges of motion, one common issue with the upright row is being so inconsistent from workout to workout that it’s hard to progressively overload our muscles. When you find a grip width and pull height that works for you, make a note of it and stick with it for at least a full training phase (3–6 weeks). Then, provided that you’re being consistent from workout to workout, feel free to vary your technique from phase to phase. That might help spur on a new wave of muscle growth, and it will give our shoulder joint a break from experiencing the exact same strain over and over again, allowing it to fully recover and adapt.

Hypertrophy Rep Range

The upright row is a small compound lift that suits moderately heavy sets of 8–15 reps. If you’re having trouble finding a comfortable technique, erring on the higher side of that rep range can help, but if the lift feels comfortable, feel free to drops as low as eight reps per set. 2–4 sets per workout often works well.

The Lateral Raise

Min-Maxing Technique

The lateral raise is done by grabbing some dumbbells, kettlebells, or weight plates and raising our arms out to the sides, sort of like an ostrich might flap his wings. Most people can do these to parallel or slightly above, and that’s great. Some people can use an even larger range of motion without pain, and that’s fine, too. Just make sure that you cut the range of motion before your shoulder joints starts cracking and popping.

Illustration of a man doing dumbbell lateral raises.

The lateral raise can be done with straight arms or, better, with slightly bent arms. And it can be done while standing straight or while bending slightly at the waist. There’s no one correct way to do it, it just needs to be done in a way that feels good on our shoulders let’s our side delts do the work.

On that note, it’s okay to drive the weight up with a bit of momentum, provided that you’re generating that momentum from your shoulders and traps. The lateral raise is easy at the beginning, hard at the end. If we accelerate the weight up, the beginning gets harder and the end gets easier. It flattens the strength curve. That’s great.

After you drive the weight up, it’s important that you lower it back down slowly and under control. Some of the muscle growth comes from lifting the weight up, but some also comes from lowering it back down. If you’re trying to build broader shoulders, best to build muscle on the way up and on the way down. To do that, you don’t need to count to three or anything, just make sure that you’re resisting gravity instead of just letting the weight fall. A second or two is fine.

Finally, if your thumbs are leading the movement upward (shoulders externally rotated) then it’s your front delts that are doing most of the lifting. The front delts are the bigger muscles. They’re stronger. You’ll be able to lift more weight that way. But we’re doing lateral raises for our side delts. Keep your pinkies high!

Whatever technique and tempo you choose, just make sure that you’re consistent with it from rep to rep and from workout to workout. When your range of motion falls short, that’s momentary muscle failure, and you may want to end your set. Or maybe not. With a small lift like this, going past failure isn’t always the worst thing. But you should at least know on which rep you hit failure, even if you decide to do a few cheat reps after that.

Similarly, every workout your goal is to outlift yourself. To do that, you need to know how much you lifted the last workout and for how many reps. If your form is inconsistent, that becomes impossible—you can find yourself using more momentum or cutting the range of motions short to create an illusion of strength gains. But illusory strength gains do not yield broader shoulders.

Muscles Worked by the Lateral Raise

The lateral raise is often thought of as a side deltoid isolation lift, and there’s some truth to that—it does work our side delts. However, as with all other side delt lifts, the lateral raise also works our upper traps.

Our upper traps tilt our scapulae up, and our side delts raise our arms out to the sides. This same thing happens in the overhead press and the upright row. There’s no getting away from it. And that’s good. After all, our upper traps improve our general strength and appearance even more than our side delts do. The more we can bulk up our traps (and neck muscles) the stronger we’ll be and the better we’ll look.

Illustration showing that having bigger trap muscles (and a bigger neck) looks better.

Even so, some people try to do lateral raises in a way that takes the traps out of the lift, but not only are they likely to fail, but they’re just going to make the lift less comfortable, worse for building overall muscle mass, and less great for improving their appearance. A better approach is to simply make sure that you can also feel your side delts working.

Fortunately, there’s no possible way for our traps to raise our arms out to the sides. All our traps do is shrug our shoulders up (tilting our scapulae). That’s part of the movement, but the main part of the movement is raising our arms out to the sides, and our side delts are the only muscle that can do that.

The good news about lateral raises is that they’re easy to set up, easy to do, easy on our shoulders joints, and easy to recover from. This makes them a great lift for beginners, and a great lift for people with cranky shoulders.

Hypertrophy Rep Range

The lateral raise is a small isolation lift that suits lighter sets of 10–30 reps. If you’re having trouble feeling your side delts working, you might want to use sets of 20-30 reps to work on your mind-muscle connection. But if everything is going smoothly, sets of 10–15 reps tend to work great. 2–4 sets per workout often works well.

Drop Sets of Lateral Raises

The lateral raise is a smaller lift that isn’t very metabolically taxing. We can string sets together with minimal rest periods without much risk of our central nervous system or cardiovascular fitness becoming our limiting factor. This makes it a great lift for doing drop sets with.

To do drop sets, start with a weight you can do 10–30 reps with, do a set, strip off around 30% of the weight—you don’t need to be precise—and then immediately do another set. Keep stripping off the weight as many times as you like, perhaps even until you’re flapping empty arms.

If you’re doing lateral raises with fixed-weight dumbbells, for example, you might jump from 25 to fifteen to ten to five-pound weights.

Side Delts That Won’t Get Sore

The trickiest thing about building broader shoulders is that the side delts are small muscles that are hard to feel working and that rarely get sore, even when you’re training them properly and even as they’re growing.

Lateral raises and upright rows done in higher rep ranges (15–30) should allow you to feel your side delts working if you min-max your technique and practice building a mind-muscle connection. But remember that only your shoulders can raise your arms out to the side. So if you make sure that your front delts aren’t doing the work, your side delts will be forced to do it.

The even bigger problem is that side delts are quite resistant to delayed onset muscle soreness, which can make it hard to figure out if you’ve trained them hard enough. So it’s not necessarily a problem if you feel any muscle soreness in your side delts. In fact, to get them sore, you may need to do an absurdly high training volume—perhaps too high. A better way of gauging progress in the short term is to see if you’re getting a little bit stronger from workout to workout. In the longer term, you can see if your shoulder circumference is increasing from month to month.

Summary

A good hypertrophy training routine should already include some bench pressing and overhead pressing, which is great for building up our front delts. And it should include some chin-ups and rows, which are great for building up our rear delts. To build broader shoulders, though, we need to build bigger side delts. Unfortunately, the big compound lifts aren’t always the best for bulking up our side delts, and so they often lag behind.

Before/after illustration of a man building broader shoulders and bigger side delts.

The three best lifts for bulking up our side delts are:

  • The overhead press, especially when doing for ten or more reps.
  • The upright row, although we need to make sure they feel comfortable on our shoulder joints.
  • The lateral raise, which is perhaps the single best lift for speeding up side delt growth.

If your routine already includes some overhead pressing, you could try adding in a set of twelve after you finish your heavy sets.

If you can find a way to comfortably do upright rows, you can do a few sets of 8–15 reps per week, adding even more volume for your side delts.

But most of all, if your side delts are lagging behind, then lateral raises are the way to catch them up. It’s normal to feel your traps working, but if you have trouble feeling your side delts doing their share, then it’s worth spending some time doing lateral raises in higher rep ranges (20–30 reps) and working on building a mind-muscle connection. If you can do that, then feel free to move into lower rep ranges afterwards (10–20 reps).

The good news is that once you get good at doing lateral raises, they’re so quick and easy to recover from that you could even add a few quick drop sets to the end of every workout, boosting your side delt training volume much higher with just a few extra minutes of lifting per week.
