How much sitting is too much?

Public-health guidance is clearer about direction than about one magic number: limit sedentary time and replace some of it with physical activity. People differ in work demands, disability, fitness, sleep, training, and total weekly activity, so an exact “never sit more than X hours” rule overstates what the evidence can support. What matters is the combination of how much of the day is sedentary, how long the uninterrupted bouts last, and how much movement you accumulate around them.

Two people can both sit for eight hours and have very different days. One may take walking breaks, commute on foot, train, and move throughout the evening. The other may stack almost all eight hours into a few uninterrupted blocks and barely move outside them. That is why the useful question is not only “how many hours did I sit?” but also “where did movement repeatedly disappear?” Breaking up a long block does not erase total sedentary time, but it gives you a practical lever that is easier to change than rebuilding an entire workday.

Wellness Project learns your recurring least-active hour and weekday from your own movement history, then surfaces those patterns in context instead of firing a generic timer every time you sit still.
