Zone 2 app tracks how much of your weekly workout time is performed in the zone 2 heart rate range, typically between 60-70% of your maximum heart rate. Aiming for 150 minutes or more of weekly exercise in zone 2 is recommended, as it optimizes endurance, enhances fat-burning efficiency, and fosters sustainable fitness gains by maintaining a balance between intensity and recovery. The optimal number of minutes to spend in zone 2 per week can vary based on individual fitness levels. _____________________ If you do not have an Apple Watch, you can connect common Bluetooth heart rate monitors, such as the Polar H10, Garmin chest strap, and new Garmin watches, to view your heart rate zone progress live during a workout. If you have an Apple Watch, use the Apple Watch app to see zones live on your wrist with haptic feedback, Siri announcements, and health metrics. If you already have a different app you like for tracking workouts, no worries; Zone 2 uses all workouts saved to your device with heart rate data to calculate your weekly zone minutes. *** Features Include *** • Weekly, monthly, & daily zone tracking based on your weekly goal with multiple chart viewing options • Strava connectivity to upload Zone 2 created distance workouts to your Strava profile • Home Screen and Lock Screen widgets for weekly Zone 2 goal progress • Compatibility with common Bluetooth heart rate monitors for live zone reporting during workouts with optional audio feedback • Apple Watch app with live zone total calculations, multiple workout screens, and optional haptic feedback and alerts • Apple Watch to iPhone mirroring during live workouts to see heart rate on the larger iPhone screen • Zone goal or open goal modes for tracking workouts • Heart rate zone calculator • Live activities on the Dynamic Island or Lock Screen _____________________ What is zone 2 heart rate training? Zone 2 training refers to exercise performed at a moderate intensity that keeps your heart rate in a specific heart rate zone, typically between 60-70% of your maximum heart rate. This is the heart rate zone where your body is able to utilize oxygen most efficiently, which can lead to a range of benefits for your fitness and health. Zone 2 training is important for a number of reasons, including: • Improved aerobic capacity: By training in the zone 2 heart rate range, your body becomes more efficient at using oxygen to produce energy, which can improve your overall aerobic capacity. • Increased fat burning: During moderate-intensity exercise, your body relies more on fat as a source of fuel, which can help to improve your body composition and reduce body fat. • Improved cardiovascular health: Regular exercise in the zone 2 heart rate range can help to strengthen your heart and improve blood flow, which can reduce the risk of heart disease. • Increased endurance: Training at a moderate intensity can help to improve your endurance and stamina, which can be particularly helpful for endurance athletes such as long-distance runners or cyclists. _______________ Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
