1. What is Heart Rate Range?

The heart rate range represents the optimal exercise intensity zone, calculated as 50-85% of your maximum heart rate (MHR). This range helps you exercise at an intensity that improves cardiovascular fitness while staying within safe limits.

2. How Does the Calculator Work?

The calculator uses the heart rate range formula:

Where:

• \( MHR \) — Maximum Heart Rate (beats per minute)
• \( 0.5 \) — Lower limit multiplier (50% of MHR)
• \( 0.85 \) — Upper limit multiplier (85% of MHR)

Explanation: The formula calculates the target heart rate zone for effective and safe exercise based on your maximum heart rate.

3. Importance of Target Heart Rate

Details: Exercising within your target heart rate range ensures you're working at an intensity that improves cardiovascular fitness without overexertion. This range is ideal for burning fat and improving endurance.

4. Using the Calculator

Tips: Enter your maximum heart rate in beats per minute (bpm). If you don't know your MHR, you can estimate it using the formula: 220 - your age.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure my maximum heart rate?
A: The most accurate method is a stress test under medical supervision. A common estimate is 220 minus your age.

Q2: Why is 50-85% of MHR the recommended range?
A: This range provides the optimal balance between cardiovascular benefits and safety for most people during exercise.

Q3: Should everyone use the same heart rate range?
A: No, individuals with certain health conditions or those new to exercise should consult a healthcare provider for personalized recommendations.

Q4: How long should I stay in my target heart rate zone?
A: For general fitness, aim for 20-60 minutes in your target zone during exercise sessions, 3-5 times per week.

Q5: Can I exceed the upper limit of my heart rate range?
A: While brief periods above your target zone can occur during intense exercise, consistently exceeding 85% of MHR may increase injury risk.
