What good posture is
Good posture is a neutral, relaxed baseline where your body is aligned without forcing tension. For desk work, that usually means:
- Head over shoulders, not jutting forward.
- Shoulders relaxed, not shrugged or rounded.
- Back supported, with a natural curve in the lower spine.
- Screen in front of you, near eye level so you are not craning your neck.
Note that good posture is not one perfect frozen pose. It is a comfortable baseline plus regular movement. Staying still too long, even in a “good” position, can still cause strain.
