Weight Loss Anaerobic Threshold Formula:
From: | To: |
The anaerobic threshold (AT) for weight loss is the heart rate at which your body switches from aerobic to anaerobic metabolism. Exercising at this intensity maximizes fat burning while maintaining sustainable effort.
The calculator uses the formula:
Where:
Explanation: This formula estimates the optimal heart rate zone for fat burning based on age-adjusted maximum heart rate.
Details: Training at your anaerobic threshold helps optimize fat burning while improving cardiovascular fitness without overexertion.
Tips: Enter your age in years. The value must be valid (between 1-120). Use a heart rate monitor during exercise to stay in this zone.
Q1: Why use 80% of max heart rate for weight loss?
A: This intensity balances calorie burn from fat while being sustainable for longer durations compared to higher intensities.
Q2: How accurate is this formula?
A: It provides a general estimate. Individual variations exist based on fitness level, genetics, and other factors.
Q3: When is the best time to measure heart rate?
A: During steady-state cardio exercise when your heart rate has stabilized (typically after 5-10 minutes of exercise).
Q4: Are there limitations to this calculation?
A: Less accurate for highly trained athletes, older adults, or those on heart rate-affecting medications.
Q5: Should I stay exactly at this heart rate?
A: Aim to stay within ±5 bpm of the calculated value for optimal fat burning.
