Walking as medicine
The harm of sitting is tied to total activity, and you do not need one hard session to offset it. Treating walking as a daily medicine, plus breaking sitting up frequently, is the lowest-threshold answer available.
Mobility & flexibility
'Sitting tightens your hip flexors and switches off your glutes' is partly right, but the fix is not passive stretching. It is standing up, walking, and loading the hips and legs so muscles held short get used again.
Walking as medicine
The metabolic harm of sitting has to be interrupted often, which is a different account from hitting a daily step total. Someone can hit their steps and still sit motionless all day; the two ledgers are separate.

What 'sitting disease' really is

久坐病到底是什么

If you sit at a computer eight or nine hours a day, you've probably heard 'sitting is bad for you' — and probably assumed the problem is 'bad posture'. But research points to a more fundamental, and less flattering, conclusion: the real variable is how long you sit still itself, not just whether you sit up straight.

Ekelund 2016 pooled data from over a million people worldwide and found sitting time is associated with higher all-cause mortality; crucially, that association is strongest in people who do little activity, and substantially attenuated — possibly eliminated — in those with a fair amount of daily moderate activity (~60-75 minutes).

That gives two clues. First, much of sitting's harm is independent of 'whether you go to the gym' — you might train an hour a day, but if the other dozen-plus hours are seated, the risk doesn't auto-zero. Second, what actually reverses it is breaking up the unbroken block of stillness and moving. The next scene shows what happens inside the body once muscle stops contracting for a long time.
