Frequently Asked Questions
Zone 2 training refers to exercising at a heart rate that is 60-70% of your heart rate reserve, which is considered a moderate intensity that improves aerobic endurance.
Zone 2 is calculated using the Karvonen formula: Target HR = ((Max HR - Resting HR) × 0.6 to 0.7) + Resting HR, where Max HR = 220 - age.
Resting heart rate accounts for individual fitness levels, making the zone calculation more personalized than using percentages of max heart rate alone.
