Apple Watch + Music + AirPods Setup
Apple Watch detects workout type → starts tracking. Music plays from Watch (no phone needed if cellular). AirPods Pro 2 transparency mode for outdoor safety.
iPhone optional during workout. Apple's ecosystem at its best.
Heart Rate Training
Apple Watch monitors heart rate continuously. Apple Fitness+ shows zones. Stay in zone 2 (60-70% max HR) for fat burn, zone 4 (80-90%) for cardio.
Knowing zones = real fitness improvement vs random working out.
Sleep + Recovery
Apple Watch sleep tracking + HRV (heart rate variability) = recovery indicator. Low HRV = under-recovered = light workout day.
Stack with Oura Ring 4 if super-into recovery optimization.
