📘 Understanding Your Target Heart Rate

Target Heart Rate (THR) is a crucial metric for maximizing the effectiveness of your workouts while staying safe. Whether your goal is fat burning, cardiovascular improvement, or peak athletic performance, knowing your heart rate zones ensures you’re training in the right intensity range.

🧮 How is Target Heart Rate Calculated?

The most basic method is based on your age:

Max Heart Rate (MHR) = 220 − Age

Your THR zones are typically a percentage of your max heart rate:

• 50–60%: Light activity / fat burn zone
• 60–70%: Moderate intensity / cardio training
• 70–80%: Vigorous / aerobic conditioning
• 80–90%: High intensity / anaerobic training

💡 Karvonen Formula (More Accurate)

If you know your Resting Heart Rate (RHR), the Karvonen formula gives a more precise THR:

THR = ((MHR − RHR) × %Intensity) + RHR
