Longevity Training scores your healthspan progress against the four tissue systems that drive how well you age: mitochondria, bone, lean tissue, and movement quality. Four banks. Each one gets weekly deposits from your wearable, automatically. No per-workout logging required. THE FOUR BANKS Mito Bank- Energy and endurance. Scored from Zone 2 minutes and short hard bursts. The metric that maps most closely to your VO2max trajectory. Bone Density- Skeletal strength. Scored from impact-weighted steps and elevation. Running counts 3×, brisk walking 2×, slow walking 1×, cycling 0×. Lean Tissue- Strength and muscle endurance. Auto-detected strength workouts plus a heart-rate-pattern model that catches lifting sessions even when you forget to log them. Movement Quality- Daily resilience. Heart-rate variability, intentional practice (yoga, pilates, tai chi, stretching), and stand-rhythm signals. ONE HEADLINE SCORE A single Cellular Fitness number, 0 to 100, weighs the four banks together. It recomputes on every read. Recovery-aware: when your HRV drops, this week's targets ease automatically. Your underlying training plan stays unchanged. LIFE STAGE PERSONALIZATION Tell us once what stage of life you are in and the framework rebalances. Heavier strength and sprint intervals for women in different life phases. Don't subscribe to that approach? One tap switches you to standard polarization instead. FOUR FITNESS TIERS, AUTO-ASSIGNED Onboarding, Starter, Intermediate, Advanced
