About Endurance Vo2 Max: Zone 2 AI
Build the Engine. Raise the Ceiling.
Zone2AI is the complete longevity protocol. We combine steady-state Zone 2 training (to build mitochondrial efficiency) with the science-backed Norwegian 4x4 Sprint Protocol (to maximize VO2 Max).
Whether you follow Peter Attia, Andrew Huberman, or Inigo San-Millán, you know that "exercise is the most potent longevity drug." Zone2AI is the only app that prescribes the exact dosage, validates your effort, and projects your future health.
INTRODUCING ZONE2AI 2.0
- The Sprint Protocol (Norwegian 4x4):
Zone 2 builds the foundation; Sprints build the skyscraper. Unlock "Sprint Credits" by completing your Zone 2 base, then redeem them for guided High-Intensity Interval Training (HIIT) designed to spike your VO2 Max.
- Zone2AI Power Score:
Are you becoming more metabolically efficient? We calculate your unique Power Score (Watts/kg) to measure exactly how much power your body can generate while remaining in a fat-burning state.
- The Path (Future You):
Don't just track today; visualize tomorrow. See how your current training trajectory impacts your predicted biological age and VO₂ Max over the next decade.
- Incline Calibration:
Training on a treadmill? Our new calibration tool helps you find the perfect incline to hit your metabolic peak without running.
From "Restoration" to "Performance," choose the path that fits your biological reality. We build a custom weekly prescription based on your age, gender, and resting heart rate.
CORE FEATURES
- True Zone 2 Validation:
We don't just log minutes. We filter your Apple Health data to find *actual* Zone 2 sessions: steady-state cardio in your personal biosignal range, sustained for as long as your personalized plan calls for. No false positives.
- Apple Watch Haptics:
Stay in the zone without looking at your wrist. Get subtle, real-time haptic feedback when you drift out of your target range during Zone 2 or Sprint sessions.
- The Weekly Dose:
Track your progress toward the ideal scientific benchmark of 180–240 minutes/week.
- Total Privacy:
No ads. No selling data. We use on-device logic and anonymized processing to generate your insights. Your biological data belongs to you.
- Universal Sync:
Works with your Apple Watch, Polar, Garmin, Strava, WHOOP: anything that writes workouts to Apple Health.
Zone2AI is built for anyone seeking to build a real zone 2 habit. From beginners to high-performance individuals: biohackers, endurance athletes, and anyone optimizing for mitochondrial health and longevity.
This is not a general fitness tracker. This is a precision tool for a longer life.
Train in Zone 2.
Sprint for VO2 Max.
Defy your age
