Buying Guide
Smartwatch vs. Chest Strap vs. Ring
Smartwatches (Garmin, Apple Watch) offer the best all-round experience with GPS, HR monitoring, and smart features. Best for most people. Chest straps (Polar H10) offer the highest HR accuracy — essential for precise Zone 2 training. Pairs with any smartwatch or app. Smart rings (Oura) excel at sleep tracking and recovery metrics. More discreet than a watch. No GPS.
What Matters for Zone 2 Training
For Zone 2 training, HR accuracy is critical. Optical wrist sensors can be off by 5-15 bpm during exercise — enough to put you in the wrong zone. Best options for Zone 2: 1. Polar H10 chest strap (most accurate) 2. Garmin watch + Polar H10 (best combination) 3. Garmin Forerunner 265 (best wrist-only accuracy)
