Perfect Posture — A Myth?

We’ve all heard it: “Sit up straight!” or “Don’t slouch!” The idea of achieving perfect posture has been drilled into us for years. But what if we told you that perfect posture is actually a myth?
In the world of physical therapy, and backed by modern research, we now understand that “the best posture is your next posture.” What does that mean, exactly?
It means our bodies aren’t designed to stay in a single position for long periods. Whether you’re sitting upright with your shoulders pulled back and core engaged, or slouched comfortably in your chair, remaining in any static position for too long can lead to discomfort or pain. Even a “perfect” posture becomes problematic when held too long, especially for those who carry tension in their shoulders, neck, or jaw. Just like athletes need variety to avoid overtraining, your body needs postural variety to stay healthy and pain-free.
If you work a desk job, consider using a sit-to-stand desk or setting reminders to move, stretch, or change positions every 30–60 minutes. The goal is to avoid staying in one position for too long. Small movement breaks can make a big difference for your health and comfort.
Think of posture like any other healthy habit: everything in moderation. Good posture today isn’t about perfection—it’s about being adaptable, efficient, and comfortable.
Now, for those with chronic conditions or past orthopedic surgeries, posture needs to be tailored to your individual experience. This is why “no size fits all” when it comes to posture.
Your posture should support you—not the other way around. Everyone’s body is different, and your posture is shaped by your work, stress, movement patterns, and more. So next time someone calls out your “slouch,” remember: movement is the magic.
