Minutes spent at moderate-to-vigorous intensity — the metric that maps directly onto public-health activity guidelines.
Detail
Active minutes count time spent at moderate-to-vigorous physical activity (MVPA), usually estimated by a device from heart rate and/or motion (some platforms call them "active zone minutes" and weight vigorous time double). They matter because they map onto the major physical-activity guidelines:
- For adults, the WHO 2020 guidelines and the U.S. Physical Activity Guidelines (2nd ed., 2018) both recommend 150–300 minutes/week of moderate activity, or 75–150 minutes/week of vigorous, or an equivalent mix, plus muscle-strengthening on 2+ days/week. Both count bouts of any length (the old 10-minute minimum is gone). Children and adolescents: ≥60 min/day.
- Many platforms credit vigorous minutes at 2× toward a weekly target, mirroring PAGA's rule of thumb that 2 minutes of moderate activity counts the same as 1 minute of vigorous.
Why track them rather than just steps: active minutes add the intensity dimension that Steps lacks. A walk to the bus and a tempo run both add steps, but only the run banks meaningful MVPA. Trending weekly active minutes is a clean general-health KPI and confirms you're meeting cardiorespiratory guidelines.
Caveats: the intensity threshold is estimated, so device active-minute totals depend on how the device infers "moderate" (HR vs motion), and HR-based credit can misfire (e.g. elevated HR from heat or caffeine while sedentary). Use the weekly total as a guideline check, not a precise dose.
Key facts
- Active minutes = time at moderate-to-vigorous intensity (MVPA).
- WHO 2020 / PAGA 2018: 150–300 min/wk moderate OR 75–150 min/wk vigorous (or mix) + 2+ strength days.
- Vigorous activity often credited 2× toward weekly targets.
- Adds the intensity dimension that step count lacks.
- Intensity threshold is device-estimated; treat totals as approximate.
Connections
- Steps — volume of movement; active minutes add intensity.
- Logging Heart Rate (Avg / Max) — HR is how many devices score active minutes.
- Cardiorespiratory Conditioning Guidelines (Peterson & Bryant / ACSM) — the targets active minutes track against.
- FITT-VP Applied to Cardio — intensity/time prescription behind the guidelines.
- KPIs for General Health — weekly active minutes is a headline health KPI.

Corrections (1)
- 2026-10-13 — Guideline figures verified against WHO 2020 and PAGA 2018 (current editions): adults 150–300 min/week moderate or 75–150 min/week vigorous (or an equivalent mix) plus muscle-strengthening on ≥2 days/week; bouts of any length count. The 'vigorous counts double' equivalence is PAGA's 2-to-1 rule of thumb (2 min moderate ≈ 1 min vigorous). Verify markers removed.
