Heart Rate Zones
Train smarter with our heart rate zone calculator. Optimize your exercise intensity by targeting specific cardiovascular zones.
Zone Training
Zone 1 (Recovery): Great for light activity and active recovery.
Zone 2 (Fat Burn): Builds base aerobic capacity and burns high % of fat.
Zone 3 (Cardio): Improves aerobic fitness and blood circulation.
Zone 4 (Threshold): Builds speed and lactic acid tolerance.
Zone 5 (Peak): Maximum effort for power and VO2 Max.
What is a heart rate zone calculator?
A heart rate zone calculator is a performance tool that identifies different levels of cardiovascular intensity based on your heart's maximum capacity. By training within specific zones, you can ensure that your body is using the right energy systems to achieve goals like fat loss, aerobic endurance, or anaerobic power.
How the calculator works
This tool uses the standard Fox Equation (220 - Age) to estimate your Maximum Heart Rate (MHR). It then subdivides this into five intensity zones ranging from Recovery (50-60%) to Peak (90-100%). For the highest precision, knowing your true resting heart rate can further refine these training protocols.
Interpretation of training zones
If your goal is sustainable weight management, focus on Zone 2 (the "fat-burning" zone). For cardiovascular strengthening and heart health, Zone 3 is the most effective. High-performance athletes and those looking to improve their speed should incorporate intervals in Zone 4 and 5, but always with adequate recovery periods between sessions.
