Cardio Heart Rate Calculator

Target Heart Rate Formula:

\[ \text{Target HR} = \text{HR}_{\text{max}} \times \text{intensity} \] \[ \text{HR}_{\text{max}} = 220 - \text{age} \]

Maximum Heart Rate (HR_max):

Target Heart Rate:

Moderate Exercise Range (50-70%):

Vigorous Exercise Range (70-85%):

1. What is Target Heart Rate?

Target heart rate is the desired range of heart rate achieved during exercise that enables the heart and lungs to receive the most benefit from a workout. This range varies based on your age and the intensity of your exercise.

2. How Does the Calculator Work?

The calculator uses the following formulas:

\[ \text{HR}_{\text{max}} = 220 - \text{age} \] \[ \text{Target HR} = \text{HR}_{\text{max}} \times \text{intensity} \]

Where:

\( \text{HR}_{\text{max}} \) — Maximum heart rate (beats per minute)
\( \text{age} \) — Your age in years
\( \text{intensity} \) — Exercise intensity as a decimal (0.5-0.9)

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

3. Importance of Target Heart Rate

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

4. Using the Calculator

Tips: Enter your age and desired exercise intensity (0.5 for moderate, 0.7-0.9 for vigorous). The calculator will show your maximum heart rate and target zones.

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 bpm due to genetics and fitness level.

Q2: What's the best intensity for fat burning?
A: Moderate intensity (50-70% of max HR) is typically recommended for fat burning.

Q3: How often should I check my heart rate during exercise?
A: Check periodically during your workout, especially when changing intensity levels.

Q4: Are there limitations to this calculation?
A: The formula may be less accurate for very fit individuals, older adults, or those on certain medications.

Q5: Should I consult a doctor before starting exercise?
A: If you have any medical conditions or concerns, consult your healthcare provider before beginning a new exercise program.
