MEN AND WOMEN OVER 40 WHO ACTUALLY TRAIN
Your Doctor Measures 2 Biological Systems. Your Performance Depends on 9.
See Where You Stand in 5 Minutes.
The Longevity Athlete Index Preview scores 3 of the 9 functional domains driving your energy, recovery, strength, and cognitive performance — benchmarked against disciplined performers, not population averages. Free. Private. No credit card.

Why "Normal" Is Costing You Performance
You Are Being Measured Against the Wrong Standard
Standard bloodwork compares you to population averages — a largely sedentary, metabolically declining sample. If your annual physical says normal, it means you have not crossed the disease threshold. It says nothing about whether your biology is supporting the performance you are demanding from it.
The Gap Between Effort and Output Is Biological
You are still training. Still disciplined. Still showing up. But recovery is slower. Energy is less predictable. Strength has plateaued. The issue is not effort — it is that the hormonal, metabolic, and inflammatory systems supporting your effort have not been measured, let alone optimized.
This Score Measures What Your Doctor Does Not
The Longevity Athlete Index evaluates biological performance across 9 functional domains — from hormonal and metabolic health to sleep architecture, stress response, and cognitive function. Your preview samples 3 of those domains in 5 minutes. The full LAI tracks all 9, updated monthly and enriched daily by your wearable data.
Your Biology Runs on 9 Systems. Your Doctor Checks 2.
The Longevity Athlete Index measures all of them — the preview quiz samples three.

Your preview score estimates 3 domains from 25 questions. Your full Longevity Athlete Index measures all 9 — monthly — and updates daily when you connect your Oura, Whoop, Garmin, or Fitbit.
Built From Functional Medicine. Designed for Performance.
The Longevity Athlete Index is a proprietary biological performance scoring system that tracks your physiology across 9 functional domains. It begins as a high-resolution assessment. Add your wearable device and it updates daily. Add blood panel data and it becomes a biomarker-confirmed measurement. Add functional labs and it reaches clinical-grade precision. No other platform combines self-reported assessment, wearable integration, blood biomarkers, and advanced functional lab data into a single evolving score — visible on one dashboard, tracked on one trajectory, from Day 1.
Why It's Different
- 9 functional domains where a standard physical checks 2–3
- 67 biomarkers analyzed at the clinical tier vs 12–15 in a conventional panel
- Integrates with Oura, Whoop, Garmin, Fitbit, and Apple Watch
- Built on functional medicine protocols, not population-average thresholds
- Your score is benchmarked against people who actually train, not the general population
Your Preview Takes 5 Minutes. What It Reveals Took Years to Build.
The Longevity Athlete Index Preview is free, private, and takes less time than your morning coffee. Your score shows you exactly where your biological performance stands — measured against a benchmark designed for people who actually train.
