Measure what matters: longevity metrics that count
Here are the markers worth tracking, and simple tests you can do at home today.
Written & reviewed by Thurairaj Manoharan, physiotherapist · Updated
Training without measurement is guesswork. Tracking gives feedback on whether the plan is working and where your weak link is. The best metrics are the ones you can act on.
Tests you can do at home
You can assess a lot with no equipment: the 30-second sit-to-stand for leg strength, single-leg balance time, a grip test, and the talk test for aerobic intensity. These functional tests reflect real-world capability, and the 30-second chair stand is used by the CDC in its STEADI fall-risk screening.
Try the quick version with our functional-age self-check on the homepage, then get the real thing measured.
The biomarkers worth tracking
The most useful markers are the trainable ones (VO₂ max, muscle and grip strength, balance, and body composition), alongside the standard health numbers your doctor tracks: blood pressure, blood sugar (HbA1c) and cholesterol. Together they show how your body is holding up.
- VO₂ max: low fitness carried a mortality risk comparable to smoking in a large Cleveland Clinic cohort (Mandsager et al., 2018). See VO₂ max training.
- Grip & strength: every 5 kg lower grip strength was linked to a 16% higher risk of death in the PURE study (Leong et al., 2015). See grip strength and longevity.
- Balance: poor balance is a recognised fall-risk factor. See balance and stability.
DEXA, VO₂ max and wearables
For deeper data, DEXA scans (body composition and bone density) and lab VO₂ max tests are available at some Klang Valley clinics, and wearables can track heart-rate zones and resting heart rate. These are useful add-ons, not requirements. The field tests above get most people started.
The point of measuring
We build measurement into our method: a baseline, then a re-test every 12 weeks, so progress is something you read rather than hope for. If you'd like your real numbers measured at home, we run baseline assessments across KL and Selangor.

What fitness tests can I do at home?
Several useful ones need no equipment: the 30-second sit-to-stand (lower-body strength), single-leg balance time, a grip test, and the talk test for aerobic intensity. Together they give a rough picture of your functional fitness.
What longevity biomarkers are worth tracking?
The most actionable are the ones you can train: VO₂ max, muscle strength (including grip), balance, and body composition, plus standard health markers like blood pressure, blood sugar (HbA1c) and cholesterol from your doctor.
Where can I get a DEXA or VO₂ max test in Malaysia?
Some private clinics and sports-science labs in the Klang Valley offer DEXA body-composition scans and treadmill VO₂ max testing. You don't need a lab to start, though. We estimate your key markers at a home baseline and track change from there.
