1. What is Active Target Heart Rate?

Active Target Heart Rate (THR) represents 80% of your Maximum Heart Rate (MHR), which is the ideal intensity for vigorous exercise that improves cardiovascular fitness while maintaining safety.

2. How Does the Calculator Work?

The calculator uses the Active THR formula:

Where:

• \( MHR \) — Maximum Heart Rate (bpm)
• \( 0.8 \) — 80% intensity multiplier for active exercise

Explanation: This calculation determines the heart rate you should aim for during vigorous exercise sessions to maximize cardiovascular benefits.

3. Importance of Active THR Calculation

Details: Training at 80% of your maximum heart rate helps improve aerobic capacity, burn calories efficiently, and enhance cardiovascular health while minimizing the risk of overexertion.

4. Using the Calculator

Tips: Enter your Maximum Heart Rate in beats per minute (bpm). For accurate results, use a measured MHR from a stress test or calculate using the formula: 220 - age.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my Maximum Heart Rate?
A: The most accurate method is through a clinical stress test. Alternatively, you can use the formula: 220 - your age, though this is an estimate.

Q2: Is 80% MHR safe for everyone?
A: While generally safe for healthy individuals, those with heart conditions or who are new to exercise should consult a doctor before exercising at this intensity.

Q3: How long should I maintain my Active THR during exercise?
A: For most people, 20-30 minutes at this intensity provides excellent cardiovascular benefits. Always include warm-up and cool-down periods.

Q4: What if I exceed my Active THR during exercise?
A: Gradually reduce your intensity. Consistently exceeding your target zone may indicate you need to adjust your training plan.

Q5: How often should I exercise at my Active THR?
A: Most fitness guidelines recommend vigorous exercise 3-4 times per week, with rest days in between for recovery.
