Fat Burning Zone Formula:
From: | To: |
The fat burning zone refers to the heart rate range where your body burns the highest percentage of calories from fat during exercise. For women, this typically occurs at 60-70% of maximum heart rate.
The calculator uses two methods:
Simple Method: \[ \text{Fat Burning Zone} = \text{MHR} \times 0.6 \text{ to } \text{MHR} \times 0.7 \]
Karvonen Method: \[ \text{Target HR} = (\text{MHR} - \text{Resting HR}) \times \text{Intensity} + \text{Resting HR} \]
Where:
Details: Training in this zone maximizes fat utilization, improves aerobic capacity, and is ideal for weight management and general fitness.
Tips: Enter your age and resting heart rate (measured in the morning before getting out of bed). The calculator provides both simple and more precise (Karvonen) fat burning zones.
Q1: Why is the fat burning zone different for women?
A: Women typically have higher maximum heart rates than men of the same age, requiring gender-specific calculations.
Q2: Is this the best zone for weight loss?
A: While it burns a higher percentage of fat, higher intensity zones burn more total calories which may lead to greater weight loss.
Q3: How accurate is the MHR formula?
A: It's an estimate. The most accurate method is a stress test, but this formula works well for most women.
Q4: How often should I check my fat burning zone?
A: Recalculate every 6-12 months or after significant fitness improvements.
Q5: Can I use this if I'm pregnant?
A: Consult your doctor as pregnancy affects heart rate and exercise recommendations.
