Body composition
The physical measures that show how much of you is working tissue, stored energy and structural support.
Bio age assessment
Measure what
can change.
AFT starts with a repeatable, independent-lab verified biological age assessment. The result is a baseline for intelligent action — not a label, diagnosis or guess about the future.
The AFT model
12 markers.
4 domains.
The AFT Bio Age itself is calculated from 12 markers across 4 domains. Broader testing gives additional healthspan context, but it does not change the definition of the model.
Fitness
Cardiorespiratory capacity and the ability to produce useful effort, recover and adapt.
Blood markers
Selected biomarkers that add biological context to the way your systems are operating.
Vital signs
Simple signals that help make change visible between deeper rounds of testing.
Data status
Your verified figure belongs here.
Bio age numbers on this site are currently held as placeholders until Lee supplies the October 2026 verified lab figures. No personal claim is made here before that update.
October 2026 verified result
[FIGURE TO UPDATE]
A repeatable baseline
Measure → optimise → verify.
Measure
Establish the baseline with the relevant lab, body composition, fitness and vital-sign data.
Optimise
Build a personal plan around the levers that matter most to your goals and context.
Verify
Repeat the relevant measures and use the change over time to decide what stays.
