Frequently Asked Questions

מצא תשובות מהירות

What is Zone 2 heart rate?
Zone 2 heart rate is a moderate intensity aerobic training zone, typically 60-70% of your heart rate reserve. It's ideal for building endurance, improving fat metabolism, and enhancing cardiovascular health without excessive stress.
How is Zone 2 heart rate calculated?
This calculator uses the Karvonen formula: Target HR = ((Max HR - Resting HR) × % intensity) + Resting HR. For Zone 2, the intensity is 60-70%, giving you a range in beats per minute (BPM).
What if I don't know my max heart rate?
If you don't enter a max heart rate, the calculator estimates it using the common formula: 220 - your age. For more accuracy, you can measure your max heart rate through a graded exercise test.
Why is Zone 2 training important?
Zone 2 training improves aerobic capacity, increases mitochondrial density, enhances fat utilization for energy, and builds a strong cardiovascular base with lower injury risk compared to high-intensity workouts.
