It usually comes from a good place. Parents, teachers and employers often say it because they want to help us avoid back pain or poor posture. The problem is that "sit up straight" isn't particularly helpful.
Many people respond by pulling their shoulders back, lifting their chest and holding themselves rigidly upright. It might look like good posture for a few moments, but it often feels tiring. Before long, the shoulders creep back up, the lower back becomes uncomfortable, and the effort fades.
If you've ever found yourself constantly correcting your posture only to end up feeling more tense, you're not alone.
There isn't one perfect posture
One of the biggest misconceptions about posture is that there's a single ideal position everyone should aim for. Research doesn't support that idea. Ultimately, our bodies are designed to move. Sitting in any position for long periods, even one that looks textbook-perfect, can become uncomfortable.
There isn't a single position that guarantees comfort or prevents back pain. But there are more helpful positions and a more helpful distribution of tension and effort that can support us in remaining pain free.
Why holding yourself upright can create more tension
When people try to improve their posture through effort alone, they often recruit muscles that don't need to be working so hard. Think about someone standing to attention. It isn't a position most of us could comfortably maintain for an entire day. Yet many people spend hours trying to recreate a milder version of it at a desk.
Holding unnecessary tension in the neck, shoulders or lower back can make movement feel less free. Instead of responding naturally as we reach, turn or breathe, we begin working against ourselves. This doesn't mean slumping is the answer either. Both slumping and sitting rigidly reduce our ability to move easily. Most of us alternate somewhere between these two extremes throughout the day.
A different way of thinking about posture
The AlexanderTechnique approaches posture from a different direction. Rather than asking, "How should I hold myself?", it asks, "Am I adding unnecessary tension?", or "Can I stop holding myself?"
During an Alexander Technique lesson, you won't be asked to memorise a perfect sitting position or force any particular position or posture.
Instead, you'll learn to notice habits that may be interfering with your natural balance and coordination. As those habits become easier to recognise and reduce or prevent, many people find sitting, standing and moving requires less effort.
The aim isn't to achieve a fixed posture. It's to improve the quality of how you organise yourself while you're moving through everyday life.
Small habits make a big difference
Many of us develop habits without realising it. You might tighten your neck every time you answer an email; hold your breath while concentrating; or, you might grip the steering wheel harder than necessary during traffic.
None of these habits are usually conscious. Over months or years they have become so familiar that they simply feel 'normal'.
Alexander Technique lessons help bring these patterns into awareness. Once you notice a habit, you have the opportunity to respond differently.
What does the research say?
The strongest research on the Alexander Technique has focused on persistent back pain rather than posture itself. A large randomised controlled trial published in the BMJ found that Alexander Technique lessons led to significant long-term improvements in pain and disability for people with chronic or recurrent back pain compared with usual care. The benefits were still present one year later. Little and colleagues suggested that learning new ways of responding to everyday movement may have contributed to these lasting improvements.
More broadly, research into posture has become increasingly cautious about blaming pain on one "bad" sitting positions. Reviews of the evidence suggest that posture on its own does not reliably predict who develops back pain. Factors such as movement variety, physical activity, previous pain, sleep, stress and general health all play a role.
This all doesn't mean posture is irrelevant. It means the picture is more complex than simply
remembering to sit up straight.
Alexander Lessons...
The most helpful change doesn't come from trying harder. It's noticing what you're already doing and allowing unnecessary effort to reduce. The quality of attention we bring to ourselves opens up the possibilities for understanding how we are and creating space for something new.
This is the kind of awareness the Alexander Technique is designed to help you develop.
If you're curious about how this works in practice, I'd be happy to show you during an individual Alexander Technique lesson in London. Lessons are practical, hands-on, and tailored to your personal everyday life activities.
