“Physical inactivity” can sound like a judgment, but in many datasets it’s defined very specifically: no leisure-time physical activity (no exercise or physical activity in the last 30 days outside of a person’s regular job).
On that definition, about 1 in 3 adults fall into the “physically inactive” category in US surveillance-style estimates. That doesn’t mean they never move—just that they report no intentional, leisure-time activity over the measured window.
Why it matters: across many lines of research and public health reporting, physical inactivity is treated as a major risk factor linked to higher rates of chronic disease (including cardiovascular disease) and related risk markers.
