WHY PLANZY WORKS — BACKED BY SCIENCE: • Adapts After Every Run Your plan adjusts automatically based on your pace, effort, heart rate, and missed workouts — no manual edits needed. • Built From Your Data We analyze your Apple Health, Garmin, or Strava history to estimate your VO₂max and set your pace zones. From this, we define your: – LT1 (aerobic threshold) – LT2 (lactate threshold) – VO₂max pace Each workout hits a specific zone to improve endurance, speed, or recovery. • Zone 2 Running — Smartly Used Your training includes enough low-intensity running to build your aerobic base — but we don’t follow the 80/20 rule blindly. If you run twice a week, we focus on high-impact sessions to help you progress faster while staying fresh.
