There's a Reason They Can't Define Good Posture for You...

Quick Overview

There is no single definition of "good posture" because evidence shows that posture is highly individual and dynamic, meaning the best posture is simply the next posture, not a fixed ideal alignment; attempts to enforce specific postures, like having the pelvis directly over the ankle or pulling shoulders back, often lead to counterproductive muscle adaptations or are based on flawed studies.

Key Points: There is little scientific evidence directly linking slouching or "bad posture" to back pain, which affects over 2.5 million people in the UK. The concept of a single, perfect posture is a myth; as Peter Opsvik states, "The next posture is the best posture," emphasizing movement over static alignment. Experts disagree on what constitutes the best posture, further indicating that a universally ideal posture does not exist. Common postural recommendations, such as keeping the pelvis over the ankle or keeping the rib cage vertically aligned over the pelvis, are often arbitrary and lack strong supporting science. Studies suggesting a link between poor posture (like Anterior Pelvic Tilt or APT) and pain are often flawed because they fail to account for the fact that active people often have variations in posture without experiencing pain. Attempts to force an 'ideal' posture, like pulling the shoulders back, can result in muscle imbalances, such as tightened chest muscles and weakened upper back muscles. Range of motion is crucial; instead of striving for a fixed position, the focus should be on coordinated movement and increasing the body's usable range of motion (09:50, 10:04).

Context: This video challenges the pervasive cultural and sometimes clinical notion that there exists one specific, universally correct posture (often termed 'good posture') that prevents back pain. It argues that this concept is a myth, citing a lack of robust evidence linking static posture to pain, and instead champions movement and individual variability, drawing on quotes from posture design experts like Peter Opsvik and referencing systematic reviews that found no consensus on posture causality for low back pain.
