Personal Information
Your Target Heart Rate Zones
How It Works: Heart Rate Zone Methodologies
Target HR = ((Max HR – Resting HR) × %Intensity) + Resting HR
where Max HR = 220 – Age
This method takes into account your individual resting heart rate and is widely used for setting effective exercise intensity, especially for aerobic and interval training.
Target HR Zone = Max HR – Zone Adjustment ± 5 bpm
Max HR = 220 – Age; Zone Adjustment is typically 50, 40, 30, 20, 10 for Zones 1-5
This method estimates training zones by subtracting set values from your maximum heart rate, providing quick reference for different effort levels.
Cardiovascular Fitness & Heart Rate Monitoring
- What is Cardiovascular Fitness? It measures how well your heart, lungs, and vessels supply oxygen during sustained physical activity. Improved fitness reduces the risk of chronic diseases and supports endurance and recovery.
- Why Train by Heart Rate Zone? Training within your ideal heart rate zones maximizes desired outcomes—fat burning, aerobic capacity, endurance, or speed—while reducing injury risk and overtraining.
- How to Measure? Use a fitness tracker, smartwatch, or a chest strap monitor for best accuracy. Check your pulse at your wrist or neck for manual readings.
- Resting HR: Measure it in the morning before rising, average for 3–5 days for best estimate.
- Zone 1 – Recovery/Easy: Boosts circulation, ideal for warm-up/cool-down.
- Zone 2 – Fat Burn: Enhances fat metabolism and aerobic efficiency.
- Zone 3 – Aerobic: Improves endurance and basic stamina.
- Zone 4 – Threshold: Increases speed and high-level performance.
- Zone 5 – VO2 Max: Used for sprinting and interval peaks, very taxing and not for all users.

Target Heart Rate Calculator – Hit Your Fitness Goals Safely & Effectively
Whether you’re a beginner or a seasoned athlete, knowing your target heart rate (THR) is essential for safe and effective workouts. The Target Heart Rate Calculator helps you find the optimal beats per minute (BPM) to aim for during exercise—so you burn fat, build endurance, and avoid overtraining.
🧠 What Is Target Heart Rate?
Your target heart rate is the range your heart should beat during physical activity to achieve specific fitness goals like fat burning, cardiovascular endurance, or performance training.
The THR is expressed as a percentage of your maximum heart rate (MHR)—usually between 50% and 85% depending on your goal and intensity.
🧮 How Does the Target Heart Rate Calculator Work?
Our Target Heart Rate Calculator uses two primary methods:
- Basic Formula (220 – Age)
- Karvonen Formula – takes resting heart rate into account
Once you input your:
- 👤 Age
- ❤️ Resting heart rate (optional)
- 🎯 Desired intensity (% of MHR)
… the tool provides your ideal BPM range for warm-up, fat burn, cardio, and high-intensity training.
🏋️♂️ Heart Rate Training Zones Explained
| Zone | % of Max HR | Goal | Feel |
|---|---|---|---|
| 1️⃣ | 50–60% | Warm-up / Recovery | Light breathing |
| 2️⃣ | 60–70% | Fat Burn | Comfortable effort |
| 3️⃣ | 70–80% | Aerobic/Cardio | Moderate breathing |
| 4️⃣ | 80–90% | Endurance / Performance | Hard, sweaty, focused |
| 5️⃣ | 90–100% | Anaerobic / Sprinting | Max output, short bursts |
🎯 Example Calculation
Age: 30
Resting HR: 65 BPM
Target Intensity: 60–80%
Max HR: 220 – 30 = 190 BPM
Target Zone:
- 60% of 190 = 114 BPM
- 80% of 190 = 152 BPM
✅ Your target heart rate zone is 114–152 BPM.
This means your heart should beat between 114 and 152 times per minute during your workout to stay in the ideal zone.
