7,000+ daily steps
Most of the longevity benefit caps at 7–10k steps. The 10k target is a marketing number, not a research one.
Why
Cohort studies show steep mortality-risk reduction from sedentary up to about 7,000 steps per day. Past 10,000 the curve flattens: additional steps are fine but the marginal benefit is small. Walking distributed throughout the day (especially after meals) is more useful than one big walk plus a sedentary day.

How
7,000 minimum; 10,000 if convenient. Distribute throughout the day. Post-meal walks count double.

Evidence
Paluch 2022 Lancet Public Health meta-analysis (15 international cohorts, n=47,471): vs ~3,500 steps/day, mortality dropped progressively through ~6,000–8,000 steps/day in adults ≥60 and ~8,000–10,000 in younger adults; the curve flattens past those targets. The 10,000-step number is marketing folklore; the cohort signal anchors most of the benefit around 7,000.
