1. What is Target Heart Rate Zone?

The Target Heart Rate Zone is the range of heartbeats per minute that you should aim for during exercise to get cardiovascular benefits. It's calculated based on your maximum and resting heart rates, and the desired intensity of your workout.

2. How Does the Calculator Work?

The calculator uses the Karvonen formula:

\[ Zone = ((MHR - RHR) \times Intensity_{min}) + RHR \text{ to } ((MHR - RHR) \times Intensity_{max}) + RHR \]

Where:

\( MHR \) — Maximum Heart Rate (beats per minute)
\( RHR \) — Resting Heart Rate (beats per minute)
\( Intensity_{min} \) — Minimum exercise intensity (0-1)
\( Intensity_{max} \) — Maximum exercise intensity (0-1)

Explanation: The formula accounts for your personal heart rate reserve (MHR - RHR) to calculate a more personalized target zone than simple percentage-based methods.

3. Importance of Heart Rate Zones

Details: Training in the correct heart rate zone helps optimize workouts for different goals (fat burning, endurance, performance) while avoiding overexertion.

4. Using the Calculator

Tips: Measure your resting heart rate in the morning before getting out of bed. For maximum heart rate, use 220 minus your age as an estimate, or get a professional assessment.

5. Frequently Asked Questions (FAQ)

Q1: What are typical intensity ranges?
A: Moderate intensity: 0.5-0.7, Vigorous intensity: 0.7-0.85. Adjust based on fitness level and goals.

Q2: How accurate is the 220-age formula?
A: It's a rough estimate. Actual maximum heart rate can vary by ±10-20 bpm due to genetics and fitness.

Q3: When should I measure resting heart rate?
A: Best measured first thing in the morning after waking naturally (not to an alarm).

Q4: Are there limitations to this calculation?
A: Doesn't account for medications, health conditions, or environmental factors that affect heart rate.

Q5: Should I stay in this zone the entire workout?
A: Interval training with periods above and below your target zone can be beneficial for fitness.
