Activity: Steps & Exercise Time
Activity: Steps & Exercise Time is a health-education page for Yuelu Body Age. Activity is a legacy Body Age entry; the current main model splits it into low/moderate aerobic duration, high-intensity duration, and steps. Read it as trend context rather than a judgment from one day.
Role in Body Age
Activity: Steps & Exercise Time is kept for older app entry points and user education. The current Yuelu Body Age model uses the split signals shown on the related pages, which makes the result easier to explain.
Current Yuelu Method
| Field | Current rule |
|---|---|
| Data source | Apple Health steps, workouts, and workout heart-rate samples |
| Lookback window | Last 7 days |
| Metric | Daily steps plus Z1-Z3 and Z4-Z5 workout minutes |
| Missing-data rule | Body Age is shown when at least 2 of the sleep, activity, and fitness dimensions are calculable |
The split model distinguishes baseline movement, endurance work, and high-intensity stimulus instead of relying on exercise minutes alone.
