1. What is Heart Rate Range?

The target heart rate range is the ideal range of heartbeats per minute you should aim for during exercise to get cardiovascular benefits. It's calculated based on your maximum heart rate and desired exercise intensity.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( 220 - \text{age} \) — Estimated maximum heart rate (beats/min)
• \( \text{min\_intensity} \) — Minimum exercise intensity (typically 0.5-0.6 for moderate)
• \( \text{max\_intensity} \) — Maximum exercise intensity (typically 0.7-0.85 for vigorous)

Explanation: The equation estimates your maximum heart rate based on age, then calculates the target range by applying intensity percentages.

3. Importance of Target Heart Rate

Details: Exercising within your target heart rate range ensures you're working at the right intensity to improve cardiovascular fitness without overexertion.

4. Using the Calculator

Tips: Enter your age in years and desired intensity range (typically 0.5-0.6 for moderate exercise, 0.7-0.85 for vigorous exercise).

5. Frequently Asked Questions (FAQ)

Q1: Is the 220-age formula accurate for everyone?
A: It's a general estimate. Individual maximum heart rates can vary by ±10-20 beats per minute.

Q2: What intensity should I choose?
A: 50-60% for moderate exercise, 70-85% for vigorous exercise. Beginners should start at lower intensities.

Q3: How does fitness level affect target heart rate?
A: Fit individuals can safely exercise at higher intensities for longer periods.

Q4: Are there limitations to this calculation?
A: It may not be accurate for people on certain medications or with specific heart conditions.

Q5: Should I use this for weight loss?
A: Lower intensities (50-70%) are often recommended for fat burning, but total calories burned matters more.
