Updated for March 18, 2026. If sitting up straight gives you neck pain, the problem is usually not that good posture is bad. The problem is that you are trying to hold a new position with the wrong muscles, in the wrong setup, for too long.
This article explains why overcorrection hurts and how to sit with less strain instead.
Quick Takeaways
- "Sit up straight" often turns into a strained neck-and-shoulder effort.
- Good sitting posture should feel supported, not militarized.
- Screen height and upper-back support matter more than willpower.
- Movement tolerance still matters more than one perfect position.
Why Overcorrection Hurts
Most people respond to posture advice by lifting the chest, pulling the head back hard, and holding the shoulders in place. That creates a posture that looks more upright for a minute but feels exhausting because the neck ends up stabilizing the whole strategy.
What to Do Instead
- Raise the screen.
- Let the chair or backrest share some of the work.
- Use a lighter chin tuck instead of forcing the head back.
- Move before the position gets stale.
The Signs You Are Doing It Better
- The neck feels calmer, not busier.
- You can breathe normally.
- You are not pinning the shoulders down or back.
- The position is repeatable, not theatrical.
Common Questions
Should I stop trying to sit upright?
No. The goal is to sit more supportively, not to abandon posture altogether.
Why does my lower back hurt too when I sit straight?
Because overcorrection often includes rib flare and low-back arching.
What is the best first fix?
Usually screen height and a less aggressive version of "upright."
