Heart Rate Zone Calculator
Calculate your target heart rate zones for fat burning, cardio, and peak performance training.
What Is the Heart Rate Zone Calculator?
Heart rate training zones help you exercise at the right intensity. The 5 zones range from easy recovery (Zone 1) to maximum effort sprinting (Zone 5). They are calculated as percentages of your maximum heart rate.
Formula
How to Use
Enter your age to calculate your maximum heart rate (or enter it manually if you know it). The five training zones are displayed with BPM ranges and descriptions.
Example Calculation
Age 30: Max HR = 190 bpm. Zone 1 (recovery): 95-114 bpm. Zone 2 (fat burn): 114-133 bpm. Zone 3 (cardio): 133-152 bpm. Zone 4 (threshold): 152-171 bpm. Zone 5 (max): 171-190 bpm.

Frequently Asked Questions
How accurate is 220 − age?
The formula is a rough estimate with ±10-15 bpm standard deviation. An actual VO2max test gives more accurate results.
What zone should I train in?
Zone 2 (fat burn) is ideal for base fitness and weight loss. Zone 4 (threshold) improves speed and cardiovascular fitness.
Can I use a heart rate monitor?
Absolutely. A chest strap or wrist monitor helps you stay in the target zone during exercise.
