How to Use Heart Rate Zones

Zone 1 (50 to 60%) is light activity and warm-up. Zone 2 (60 to 70%) is fat burning and endurance base. Zone 3 (70 to 80%) is aerobic fitness. Zone 4 (80 to 90%) is high-intensity cardio. Zone 5 (90 to 100%) is max effort and speed work.

When you enter your resting heart rate, the calculator uses the Karvonen formula for more personalized zones.
