1. What is Target Heart Rate?

Target Heart Rate (THR) is the desired heart rate range during exercise that indicates the intensity of training. For cardio exercise at 70% intensity, it's calculated as 70% of your Maximum Heart Rate (MHR).

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( THR \) — Target Heart Rate (bpm)
• \( MHR \) — Maximum Heart Rate (bpm)
• \( 0.7 \) — 70% intensity multiplier for cardio exercise

Explanation: This calculation helps determine the optimal heart rate for cardiovascular exercise at moderate intensity.

3. Importance of Target Heart Rate

Details: Training at the appropriate target heart rate ensures you're working at the right intensity to improve cardiovascular fitness without overexertion.

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: What is Maximum Heart Rate (MHR)?
A: Maximum Heart Rate is the highest heart rate an individual can achieve during maximal physical exertion.

Q2: Why use 70% of MHR for cardio?
A: 70% of MHR represents moderate intensity exercise, ideal for improving cardiovascular endurance and burning fat.

Q3: How accurate is the 220-age formula for MHR?
A: It's a general estimation. Individual MHR can vary by ±10-20 beats due to genetics, fitness level, and other factors.

Q4: Should everyone exercise at 70% MHR?
A: Exercise intensity should be tailored to individual fitness levels and goals. Beginners may need to start at lower intensities.

Q5: How long should I maintain my target heart rate during exercise?
A: For cardiovascular benefits, aim for 20-60 minutes of continuous exercise at your target heart rate, 3-5 times per week.
