How to Fix Rounded Shoulders: Do Stretches Actually Work?
Strengthen the muscles of your upper back. A 2024 meta-analysis of 23 studies found strengthening exercise produced large improvements in posture, while stretching alone had no measurable effect. Programs that improve rounded shoulders typically run 6 to 12 weeks, about three sessions a week, with rows and other pulling and shoulder blade exercises at the core.
That goes against the usual advice to stretch your chest and wait. Below is what causes rounded shoulders, why strengthening beats stretching, a simple routine you can add to your training, and what research says about pain, posture braces and how long the fix takes.
What Causes Rounded Shoulders?
The usual explanation is a muscle imbalance: the small chest muscle under your pecs (pectoralis minor) shortens, while the muscles between and below your shoulder blades get weaker. The shoulders then roll forward. It often comes with a forward head and a rounded upper back, a pattern sometimes called upper crossed syndrome.
A 2024 systematic review in BMC Musculoskeletal Disorders describes the rhomboids, trapezius and serratus anterior as the most important stabilizers of the shoulder blade. It notes that these muscles tend to weaken in upper crossed syndrome, and cites the classic view that a shortened pectoralis minor and a weak middle trapezius can produce rounded shoulders.
Long hours at a desk, on a phone or behind the wheel are often blamed, though the research on causes is far thinner than the research on fixes. The practical point is the same either way: the muscles that pull your shoulders back need more work.
Does Stretching Fix Rounded Shoulders?
Not on its own. The best current evidence shows that stretching, whether done once or regularly for weeks, doesn't change posture in a measurable way. Strengthening does. If you only have time for one, spend it on upper back exercises rather than doorway chest stretches.
The 2024 meta-analysis in Sports Medicine Open pooled 23 studies with 969 healthy participants. Neither acute stretching nor long-term stretching had a significant effect on posture. Long-term strengthening produced large improvements and was clearly superior to stretching, with the biggest effects in the upper and middle back and neck.
The authors concluded that moderate-certainty evidence "does not support the use of stretching" to treat muscle imbalance, and that programs should focus on strengthening the weakened muscles. Stretching can still feel good and may help you get into position. In a 2015 study of 15 young men, stretching the pectoralis minor right before a shoulder blade exercise reduced rounding more than the exercise alone within that session.

Which Exercises Help Fix Rounded Shoulders?
Exercises that train your middle and lower trapezius, rhomboids and serratus anterior. In practice, that means rows, face pulls, band pull-aparts, prone Y raises and the push up plus. Do them two to three times a week for sets of 10 to 20 controlled reps, squeezing your shoulder blades back and down on each one.
The 10 to 20 rep range isn't arbitrary. One of the trials in the 2024 Sports Medicine Open review trained people with forward shoulders three times a week for six weeks, using 3 sets of 10 to 20 reps for the trapezius and rhomboids. Here's a simple routine built around the same muscles:
| Exercise | Main muscles | Sets ร reps |
|---|---|---|
| Chest-supported or cable row | Middle trapezius, rhomboids | 3 ร 10 to 15 |
| Face pull | Rear shoulders, middle trapezius | 3 ร 12 to 20 |
| Band pull-apart | Rhomboids, rear shoulders | 3 ร 15 to 20 |
| Prone Y raise | Lower trapezius | 2 ร 10 to 15 |
| Push up plus | Serratus anterior | 2 ร 10 to 15 |
You can add these to the end of an upper-body session or run them as a short standalone workout. Pull ups and chin ups also train the upper back; our guide on pull ups vs chin ups covers both.
How Long Does It Take to Fix Rounded Shoulders?
Most studies that improved rounded shoulders ran for 6 to 12 weeks, with about three sessions a week. Some people notice they sit and stand taller within a few weeks, but plan on two to three months of consistent work for a lasting change you can see in photos.
A 2026 meta-analysis of 28 randomized trials in BMC Sports Science, Medicine and Rehabilitation included 901 people with upper crossed syndrome. Most programs lasted 6 to 12 weeks, commonly three sessions a week, at 20 to 70 minutes per session. Corrective exercise produced large improvements in the forward shoulder angle, the forward head angle and upper back rounding.
The routine above takes far less time than an hour. Ten to fifteen minutes added to two or three workouts a week covers the same muscles. Take a side-on photo before you start and again every four weeks, in the same spot and lighting, so you can see whether it's working.
Do Rounded Shoulders Cause Shoulder Pain?
Not as clearly as you might think. Research hasn't found a strong link between upper back rounding and shoulder pain, and correcting posture doesn't reliably reduce pain. Posture does affect how far you can lift your arms, though, which matters for overhead pressing and other lifts.
A 2016 systematic review in Manual Therapy found moderate evidence of no difference in upper back rounding between people with and without shoulder pain. It also found strong evidence that people can raise their arms further when sitting or standing upright than when slouched.
The 2026 meta-analysis reached a similar conclusion from the other direction. Corrective exercise clearly improved posture, but its effects on pain, function and muscle strength were inconclusive. If you have ongoing shoulder or neck pain, see a physiotherapist or doctor instead of assuming posture is the cause.
Should You Stop Bench Pressing If You Have Rounded Shoulders?
No. The research on fixing rounded shoulders points to strengthening your upper back, not to avoiding chest work. Keep pressing, but make sure your weekly pulling volume at least matches your pushing volume, and add the shoulder blade exercises above.
A simple way to balance your program is to pair every pressing exercise with a pulling one. If you bench press, follow it with a row; if you overhead press, add a pull up or face pull. Our guide on how to get bigger shoulders shows how to train the rear delts too. You'll train your back hard enough to support good posture without giving up the lifts you enjoy. For pressing technique that keeps your shoulder blades set, see how to increase your bench press.
FAQ
Do posture correctors fix rounded shoulders?
They may help you hold a better position while you wear them. In one small study, a shoulder brace worn during an exercise reduced rounding within that session. But lasting changes in the research came from strengthening programs over weeks, so treat a brace as a reminder, not a fix.
Can rounded shoulders be fixed permanently?
They can be improved a lot. Trials lasting 6 to 12 weeks found large changes in shoulder posture. Like any training result, though, the improvement depends on keeping the work up. Leaving the upper back exercises in your routine is the easiest way to keep your new posture.
Do face pulls fix rounded shoulders?
They help, because they train the rear shoulders and middle trapezius, two of the muscles that pull your shoulders back. Face pulls work best as one part of a routine that also includes rows and lower trapezius work, rather than as the only exercise.
Is it bad to have rounded shoulders?
Not necessarily. Rounded shoulders aren't strongly linked to shoulder pain in research. But slouching does limit how far you can raise your arms, and many lifters simply prefer how they look and feel when standing taller, which is reason enough to train the upper back.
