Why this replaces free-squat norms.
Free bodyweight squat counts vary with depth, stance, balance and judging. The one-minute sit-to-stand has a fixed endpoint and published percentiles. The cited 2025 norms come from 499 healthy Chilean adults, so ethnicity, chair geometry and activity level may affect comparison.
