Swap your chair twice a day and reset your pelvis, spine and breath in under twenty minutes.
The advice to "sit on a ball all day" is bad advice, and it is the fastest way to end up with a sore back and a deflated ball. What works is intermittent use.
A ball gives no back support, by design. That is useful for twenty minutes, while the postural muscles are fresh. After ninety minutes those muscles fatigue and you slump — and slumping unsupported is worse than slumping in a chair.
The measurable effect is not strength, it is variability. Sitting on a ball produces many small position changes per minute where a chair produces almost none. Load that keeps moving is tolerated far better than load that never does.
The best posture is the next one. A ball simply makes the next one arrive sooner.
