Eight hours of sitting beats one hour of training. Change the chair.

Most back advice starts with stretching. It should start with arithmetic: you train for one hour and sit for eight. Whatever your chair does to your pelvis, it does it eight times longer — and a flat, collapsed seat quietly tilts you backwards all day.

Level the seat first

A memory foam cushion with a coccyx cutout lifts the sit bones and drops the knees slightly below the hips. That single angle change stops the lower back from rounding and takes pressure off the tailbone — no willpower required.

Reset the shoulders twice a day

Sitting loads the traps as much as the spine. Ten minutes of warmth and kneading at midday and again after work keeps the upper back from locking into a desk shape.

What to expect, honestly

Week one: fewer end-of-day aches. Week three: you stop shifting in your seat every ten minutes. It isn't a cure for a bad back — it's removing the thing that keeps causing one.
