How to test your biological age at home: 5 simple tests anyone can do

What if you could estimate your biological age in 15 minutes, at home, without a blood draw? The five tests below measure lower-body strength, balance, flexibility, upper-body fitness, and musculoskeletal function — no needles required.

What you’ll learn:

• 5 validated physical tests you can do today
• Score each against age-based norms
• What your combined results reveal about biological age

Quick answer

What if you could estimate your biological age in 15 minutes, at home, without a blood draw? The five tests below measure lower-body strength, balance, flexibility, upper-body fitness, and musculoskeletal function — no needles required.

Key takeaways

• 5 tests estimate functional biological age in 15 minutes
• No blood work needed
• Physical performance predicts mortality as strongly as biomarkers
• Retest every 4–8 weeks

Why physical tests work

Physical performance tests capture the integrated output of nervous, muscular, skeletal, and cardiovascular systems. Grip strength (measure at home), walking speed, and sit-to-stand performance predict mortality as strongly as traditional biomarkers. For a broader view of all 7 tests backed by longevity research — including push-ups and VO2 max — see functional fitness tests that predict longevity.

Test 1: 30-second chair stand

Stand and sit from a chair as many times as possible in 30 seconds.

Age	Below avg	Average	Above avg
40–49	< 18	18–25	> 25
50–59	< 15	15–22	> 22
60–69	< 12	12–17	> 17
70–79	< 10	10–15	> 15

Test 2: Single-leg balance

Stand on one leg near a wall. Time how long. Best of 3 per side.

Age	Below avg	Average	Above avg
40–49	< 20 sec	20–40 sec	> 40 sec
50–59	< 15 sec	15–30 sec	> 30 sec
60–69	< 10 sec	10–22 sec	> 22 sec
70–79	< 5 sec	5–15 sec	> 15 sec

Inability to hold 10 sec after 50 linked to nearly double mortality risk (BJSM, 2022).

Test 3: Sitting-rising test

Sit cross-legged on floor, rise to standing. Start 10 points. -1 per hand/knee used, -0.5 per balance loss.

Score	Meaning
8–10	5–20 years younger
6–7.5	Age-appropriate
3.5–5.5	5–10 years older
0–3	10–15 years older

Score 0–3 = 5–6x mortality risk. Details: sit-to-stand longevity guide.

Test 4: Push-ups

Max consecutive push-ups, good form.

Men / Women:

Age	Men avg	Women avg
40–49	10–16	5–11
50–59	7–12	3–7
60+	5–10	2–5

40+ push-ups = 96% cardiovascular event reduction over 10 years (Harvard, 2019).

Test 5: Sit-and-reach flexibility

Sit legs extended, reach past toes. Measure in inches/cm.

Age	Men	Women
40–49	9–14 in (23–36 cm)	11–16 in (28–41 cm)
50–59	7–13 in (18–33 cm)	9–15 in (23–38 cm)
60+	5–11 in (13–28 cm)	7–13 in (18–33 cm)

Calculate your biological age

Per test: above avg = −3 years, average = 0, below avg = +3. Sum ÷ 5 + chronological age = estimate.

For comprehensive assessment with blood data: PhenoAge guide. To see exactly where your scores fall relative to population norms — with “poor,” “average,” “good,” and “excellent” cutoffs across strength, cardio, balance, and flexibility — see fitness benchmarks by age.

How SuperAge helps

SuperAge tracks walking asymmetry, double support time, walking speed, steps via Apple Health. Calculates biological age from wearable + manual data.

FAQ

Without blood work?

Yes for functional age. Add PhenoAge for metabolic markers.

How often retest?

Every 4–8 weeks individually, full assessment every 3 months.

Are home biological age tests accurate?

They estimate functional age, not a medical diagnosis. Use the result as a trend signal, then combine it with wearable data and blood markers when you need a fuller biological-age picture.
