Why “good posture” at a desk fails
Any held position, however correct, becomes expensive after ninety minutes. The muscles maintaining it stop alternating between work and rest, blood flow reduces, and the system begins to treat the position as the only option. Telling someone to hold a different fixed position moves the pain; it does not remove it.
What actually helps
- Variation. Several ways of sitting, used in rotation. This is the single most important factor.
- Noticing early. Catching the onset of bracing in the first minute rather than the ninetieth.
- Eyes and head. How you hold your head determines the load down the whole spine, and most desk workers hold it forward.
- Breathing. Shallow breathing at a desk stiffens the chest and neck together.
- Regular interruptions. Two minutes of movement every half hour beats an hour at the gym.
A two-minute desk sequence
Sit forward on your chair, feet flat. Slowly roll your pelvis back and forward a few times, small. Let your head follow, then lead, then do neither. Rest. Then turn your head gently to look behind you, first one side then the other, letting your ribs come with it. Stand up and notice what changed. That is the principle: small, slow, varied, no stretching.
What Feldenkrais adds to an ergonomic setup
Ergonomics changes the environment. This changes how you use yourself inside it. People who have both usually find the ergonomic equipment finally starts working properly, because they have learned to vary how they sit rather than perching rigidly in the position the equipment was designed for.
The complaints this suits
Neck and shoulder tension, upper back stiffness, wrist and forearm load, lower back aching by the end of the day, tension headaches, and the general sense of having become stiff. All of these are load-distribution problems, which is what the method addresses.
