Yes, you can get wider shoulders if you have rounded shoulders, but it requires focusing 80% of your effort on your back and side delts, not pressing more weight. If you've been hammering overhead presses and front raises only to see your posture worsen and your shoulder width stay the same, you're not weak-you're just solving the wrong problem. Your rounded shoulders are a structural issue, and until you fix the foundation, any new muscle you build will just sit on a collapsed frame, making the rounding more obvious.
Rounded shoulders are caused by an imbalance: your chest and front delts are too tight and strong relative to the muscles in your upper back (rhomboids, rear delts, and mid-traps), which are weak and overstretched. Every time you do a bench press, push-up, or even a poorly executed overhead press, you reinforce this imbalance. You're essentially strengthening the muscles that pull your shoulders forward and inward. Trying to build wider shoulders in this state is like trying to build a taller building on a crumbling foundation. It won't work, and it's a fast track to shoulder pain and impingement.
The visual effect of “width” doesn’t come from the front of your shoulder; it comes from the medial (side) deltoid. This is the muscle that creates the “cap” on the shoulder, making you look broader in a t-shirt. But if your shoulders are rolled forward, this muscle is poorly positioned to grow and is visually hidden. The first step isn't to build more muscle-it's to pull your shoulders back into the correct position so the muscle you *do* build is actually visible.
Your body is a system of levers and pulleys. Rounded shoulders mean the pulleys in the front (your chest and front delts) are winning the tug-of-war against the pulleys in the back. To fix this, you must strengthen the muscles that pull your shoulders back and open up your chest. This is where the 2:1 Pull-to-Push Ratio comes in. For every single set of a pushing exercise you do (like a bench press or overhead press), you must perform two sets of a pulling exercise (like a row or face pull). This is non-negotiable for the first 12 weeks.
Think about your current routine. Most people naturally do the opposite. A typical chest day might have 12 sets of pressing and maybe 3-4 sets of a token row at the end. That's a 1:4 pull-to-push ratio, which actively creates rounded shoulders. Reversing this is the single most powerful change you can make.
Here’s the simple math:
This isn't just about posture. A strong upper back creates a stable shelf from which you can press more weight safely. By prioritizing your back, you not only fix your rounded shoulders but also build the foundation to become much stronger on your presses later on. Neglecting this is the #1 reason people get stuck with narrow, painful shoulders for years.
This isn't a quick fix; it's a structural rebuild. You have to earn wider shoulders by first fixing the postural debt you've accumulated. Follow this plan for 12 weeks without deviation. The goal is to first pull the shoulder girdle back into place, then build the medial delt for width.
Your only goal for the first month is to bombard your upper back with volume. During this phase, you will cut your total pressing volume (all chest and shoulder presses) by 50%. If you normally do 12 sets for chest, you now do 6. This feels wrong, but it's essential to allow your back muscles to catch up.
Now that your posture is improving, we can focus on directly building the medial deltoid. This is where you'll start to see a change in width. The key here is perfect form and light weight. Your medial delts are small muscles; they don't need a 45-pound plate to grow.
With a stronger back and activated medial delts, you can now re-introduce pressing volume, but in a smarter way. Continue to maintain the 2:1 pull-to-push ratio.
Notice how the pulling sets (8 total) still outnumber the pushing sets (6 total), maintaining a healthy ratio while allowing for strength and size gains everywhere.
Progress isn't just about what you see in the mirror. For this issue, it's about how you feel and stand. Here is a realistic timeline.
You do not need to stop bench pressing, but you must treat it as an accessory, not a primary goal, for the first 12 weeks. Reduce your volume by 50% and ensure you are doing at least double the volume for your back on the same day.
For the medial deltoid, higher reps are superior. Aim for 12-20 reps per set on exercises like lateral raises. The medial delts are a slow-twitch dominant muscle fiber, responding better to longer time under tension and metabolic stress than to extremely heavy weight.
The most common mistake is using momentum and shrugging with the traps. To fix this, use a lighter weight (10-20 lbs is plenty), lean your torso forward about 15 degrees, and think about pushing the weights out to the side walls, not lifting them up.
During the 12-week correction phase, you should train your back directly 3-4 times per week. This can be a few sets of face pulls and band pull-aparts at the end of every workout. Train your medial delts directly twice per week on your upper body days.
Stretching your pecs is just as important as strengthening your back. The single best stretch is the doorway pec stretch. Stand in a doorway, place your forearms on the frame with elbows slightly below shoulder height, and gently step through until you feel a stretch in your chest. Hold for 30-45 seconds.
