Your comparison
Enter at least one latest measurement to see results.
Interpretation and limits
Compare records taken under similar conditions. A numerical change does not establish a change in disease risk.
The chair-stand reference applies only to ages 60–94 and the CDC protocol: a straight-backed, armless chair with a 17-inch seat, arms crossed, full stands over 30 seconds, with someone beside you for safety. If arms are needed, CDC records zero and stops the test. Do not attempt this test alone or if unsafe. Other balance and walking entries have no automatic population category. Outside the reference age range, only recorded values and changes are shown.
No biological-age years, survival probabilities or overall health score are calculated. Domain scores, where shown, describe progress toward an explicit guideline target. They are not calibrated risk predictions.
Sources and calculation details
Checked October 3, 2026. Absolute change is latest minus earlier. Percentage change divides by the absolute earlier value and is omitted for zero baselines. Activity uses moderate minutes plus twice vigorous minutes, divided by 150; strength uses days divided by two. Displayed target coverage is capped at 100% without implying extra activity lacks benefit. Dates describe records, not annualized rates.
