What Is Good Posture? (And Why It’s Not What You Think)

For years we’ve been told that good posture means sitting bolt upright, shoulders pinned back, chin tucked, core switched on. But that idea has been discredited.

Good posture isn’t a shape. It isn’t a position you hold. It isn’t a military‑style pose you maintain all day.

Good posture is your next posture.

We’re humans, not statues. We’re designed to move, shift, fidget, lean, twist, perch, slouch, and readjust. The longer we stay in any position, even one that looks “perfect”, the more likely we are to feel stiff, achy, or irritated. Think about how you feel after sitting in a car for two hours. You haven’t been slouching. You haven’t been “doing it wrong”. You’ve just been still , and stillness creates stiffness.

So what posture should you adopt?

The simple answer: the one you’re not currently in.

Your body thrives on variety. That means:

• Change position often, every 10–20 minutes if possible.

• Switch sides if you’re sitting asymmetrically.

• Swap between slouching and sitting tall.

• Stand, sit, perch, lean, mix it up through your day.

• Prioritise comfort over “correctness”.

Your body isn’t asking you to hold the “right” shape. It’s asking you to keep moving.

The real goal: comfort, ease, and adaptability

When you stop chasing the perfect posture and start giving your body variety, you reduce tension, improve circulation, and help your nervous system feel calmer and safer.

Movement is medicine , and posture is simply a series of movements.
