1. What is a Target Heart Rate Calculator?

Definition: This calculator estimates your ideal heart rate ranges for moderate and vigorous exercise based on your age.

Purpose: It helps individuals exercise at the right intensity for cardiovascular benefits and safety.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• 220 - age = Maximum Heart Rate (bpm)
• 0.6-0.73 = Moderate exercise intensity (50-70% of max)
• 0.74-0.85 = Vigorous exercise intensity (70-85% of max)

Explanation: The formula estimates your maximum heart rate based on age, then calculates target ranges for different exercise intensities.

3. Importance of Target Heart Rate

Details: Exercising within your target heart rate zone ensures you're working hard enough to improve cardiovascular fitness, but not so hard that you risk overexertion.

4. Using the Calculator

Tips: Simply enter your age in years. The calculator will show your moderate and vigorous exercise heart rate ranges.

5. Frequently Asked Questions (FAQ)

Q1: Why is 220 used in the formula?
A: 220 is the estimated maximum heart rate for a newborn, which decreases by about 1 bpm per year as we age.

Q2: Is this formula accurate for everyone?
A: It's an estimate. Individual variations exist based on fitness level, genetics, and medications.

Q3: What if my heart rate goes above the vigorous range?
A: This may indicate you're working too hard. Slow down unless you're an athlete under supervision.

Q4: How do I measure my heart rate during exercise?
A: Use a heart rate monitor, or take your pulse for 15 seconds and multiply by 4.

Q5: Should I consult a doctor before starting exercise?
A: Yes, especially if you have any medical conditions or are new to exercise.
