How to use this calculator
Enter age, resting heart rate, walking goal, current walking heart rate, and weekly walking volume. The calculator estimates your target training zone.
Calculate your target heart-rate zone for walking using age, resting heart rate, goal, and current walking heart rate. The result shows fat-burn, endurance, or cardio zone status.
Enter age, resting heart rate, walking goal, current walking heart rate, and weekly walking volume. The calculator estimates your target training zone.
The result compares current walking heart rate with the goal zone. Being too low may limit stimulus; too high may reduce sustainability.
Heart-rate formulas are estimates. Medication, heat, fatigue, and device accuracy can affect readings.
A 40-year-old with 65 bpm resting heart rate has an estimated max of 180 bpm. A fat-burn walking zone may be around 123–140 bpm.
Many people use about 50–65% of heart-rate reserve for easier fat-burn-focused walking.
Zone 2 walking can support high consistency and calorie burn, especially when repeated weekly.
Heat, dehydration, stress, low fitness, caffeine, illness, or hills can raise walking heart rate.
Consistent aerobic walking, recovery, hydration, and gradual progression can lower effort at the same pace.
Yes, brisk walking, hills, and consistent weekly volume can improve aerobic capacity over time.
