Why Train in Zones?
Heart rate zones help you control the intensity of your workout to achieve specific goals.
Fat Burning (Zone 2): Lower intensity where the body primarily uses fat for fuel. Good for endurance.
Cardio (Zone 3): Moderate intensity that improves aerobic capacity and cardiovascular health.
Formulas Used
Standard Formula: Max HR = 220 - Age. This provides a general baseline.
Karvonen Formula: Takes your Resting Heart Rate into account. Target HR = ((Max HR - Resting HR) × %Intensity) + Resting HR. This is more personalized and accurate.
