Enter your information to determine your optimal heart rate zones for different exercise intensities.

Heart Rate Reserve (HRR): The difference between your maximum and resting heart rate, used for personalized training zones
Karvonen Formula: A method that accounts for resting heart rate to provide more accurate target zones
Maximum Heart Rate: Estimated as 220 minus your age, or can be measured during a stress test
Resting Heart Rate: Best measured first thing in the morning before getting out of bed
Training Zones: Different intensity levels for various fitness goals and adaptations

Very Light (50-60%): Recovery, warm-up, and cool-down activities
Light (60-70%): Fat burning, building aerobic base, suitable for long duration
Moderate (70-80%): Aerobic fitness, cardiovascular health, recommended for most exercise
Hard (80-90%): Anaerobic threshold, performance improvement, lactate tolerance
VO₂ Max (90-100%): Maximum effort, speed work, only sustainable for short periods
