Why “Perfect Posture” Isn’t the Goal

Sit up straight. Pull your shoulders back. Stop slouching.

Most of us have heard some version of this our entire lives. We’ve been taught that there’s such a thing as good posture and bad posture, and that sitting or standing the “right” way is better for our bodies.

There really isn’t one perfect position your body is supposed to stay in. At A Life in Balance, we’re much more interested in what happens when you move than how straight you’re sitting or where your shoulders are. Your posture should be able to change as you reach, bend, walk, exercise, or breathe.

As Dr. Paula explains, “Posture is not a position to hold. It’s a strategy to interpret.”

Your posture gives us clues about how your body has learned to move and adapt. We’re not trying to make it look perfect. We want to see that it can change.

What Does Good Posture Actually Mean?

When people think about good posture, there’s usually a picture that comes to mind: shoulders back, spine straight, head up, feet planted. And there’s nothing wrong with sitting or standing that way. It just doesn’t need to be the “right” position, with everything else labeled as bad posture.

Think about how much your body changes position over the course of a normal day. You lean forward to talk to someone across the table. You curl up on the couch to read. You reach to pick up a child, bend down to tie your shoe, or shift your weight while standing in line. Your body was made to do all of those things, not stay perfectly stacked in one position.

That’s why Dr. Paula is less concerned with what your posture looks like in a single moment and more interested in whether it can change. As she explains, “A posture that can change is not a problem.”

We pay closer attention when your body keeps returning to the same position or has trouble moving out of it.

Your Body Isn’t Meant to Stay Still

This is where the idea of proper posture can get a little misleading. You can sit beautifully upright at your desk, but if you barely move for the next three hours, holding that “good” position may not be doing you as many favors as you think.

One six-month study of office workers at higher risk for neck and back pain found a big difference when people moved more often. Just 17% of those who took regular active breaks developed new neck pain, compared with 44% in a control group. Interestingly, the group that stayed seated but regularly changed positions also had a 17% rate. New low-back pain followed a similar pattern: 7–9% in the two groups that moved or shifted positions compared with 33% in the control group.

Dr. Paula likes to compare the body to a Slinky. It works because it can compress, stretch, and change shape as it moves. Our bodies need to be able to do that, too. Trying to hold one “perfect” position all day can work against the very thing we want: a body that can move comfortably and adjust when it needs to.

So the next time you catch yourself wondering, “Am I sitting correctly?” try paying attention to something else first: How long have I been sitting this way?

What Your Posture Can Tell Us

If we’re not trying to “fix” your posture, why pay attention to it at all?

Because posture can give your physical therapist useful clues, what we really want to see is what happens once you start moving. You might be comfortable standing still but feel stiff when you squat or reach overhead. Sitting up straight might be easy for a few minutes but surprisingly tiring after a while. Those are the kinds of things that tell us more about your movement patterns than a snapshot of you standing in one position.

We also pay attention to your breathing. As we explored in our blog about breathwork in physical therapy, the way you breathe and the way your body supports movement are closely connected. How easily you can breathe in different positions can tell us something, too. 

This is why someone can look like they have good posture and still feel stiff or uncomfortable, while someone who doesn’t fit the traditional picture of “perfect posture” may move just fine. What we see from the outside is only part of the story.

Not Every Posture Needs Fixing

Anterior pelvic tilt is a perfect example. That’s when your pelvis tips forward and your lower back looks a little more arched. Spend five minutes searching how to improve posture online, and there’s a good chance someone will tell you it’s something you need to fix.

Dr. Paula would disagree. “Anterior pelvic tilt is a posture, not a problem.”

Your pelvis is supposed to move. If it can shift out of that forward tilt when you bend, walk, exercise, or change positions, the fact that it likes to hang out there sometimes isn’t cause for alarm. It’s when your body has trouble leaving a position that we start paying closer attention.

And your pelvis isn’t the only body part that gets unfairly judged. Rounded shoulders and slouching have been taking the blame for bad posture for years. But seeing someone slouched over their phone or curled up on the couch doesn’t tell us much by itself. We’d rather know whether that person can move comfortably into other positions than whether they’d pass a correct posture test.

So, How Should You Improve Your Posture?

For starters, you can stop checking every five minutes to see if your shoulders are back. Instead of trying to hold yourself in one “right” position all day, think about giving your body more chances to move. A few easy places to start:

• Change positions regularly. Shift in your chair, cross and uncross your legs, stand for a while, or move somewhere else entirely. There’s no prize for sitting perfectly still.

• Get up when you’ve been sitting for a while. Walk to refill your water, take a lap around the office, or find another excuse to move for a few minutes.

• Move in different ways. Reach, bend, stretch, walk, squat, get down on the floor. Your body benefits from having more than one way to move.

• Notice what feels difficult. If getting up after sitting always leaves you stiff or certain movements consistently feel uncomfortable, that’s helpful to know.

• Don’t panic when you catch yourself slouching. Curling up on the couch is allowed. Just don’t make it your only position for the next six hours.

The goal of holistic physical therapy isn’t to teach you how to hold a perfect pose. We want to understand why certain movements or positions are harder for you, then work on giving your body more options.

The Bottom Line: Your Posture Doesn’t Need to Be Perfect

You don’t need to spend your day pulling your shoulders back, sitting up straighter, or worrying every time you catch yourself slouching. Good posture isn’t about getting your body into one ideal position and keeping it there. Your body should be able to move, shift, and change positions throughout the day.

If certain positions are uncomfortable, you’re always feeling stiff, or you just don’t move as easily as you used to, it may be worth taking a closer look. And no, we’re not going to tell you to sit up straighter. At A Life in Balance, we offer physical therapy in Flemington, NJ, and Stratton, VT.
