Find your target heart rate zones for effective, safe exercise based on your age.
Calculate your target heart rate zones instantly.
Heart rate is the number of times your heart beats each minute, commonly measured in beats per minute (BPM). It changes throughout the day depending on your activity level, emotions, fitness, medications, body temperature, and overall health.
Your heart continuously pumps oxygen-rich blood throughout the body. During exercise or physical activity, your muscles require more oxygen, causing your heart to beat faster. While resting or sleeping, your heart rate naturally slows because your body requires less oxygen.
Monitoring your heart rate helps you understand how hard your heart is working during exercise and can assist in planning workouts that match your fitness goals.
This calculator estimates your maximum heart rate and training heart rate zones using your age. These values help determine the intensity of different exercise levels.
Maximum Heart Rate = 220 − Age
This is one of the most commonly used estimation formulas for exercise planning.
Although this equation is widely used, actual maximum heart rate can vary from person to person due to genetics, fitness level, and medical conditions.
Different exercise intensities correspond to different percentages of your maximum heart rate.
| Zone | % of Maximum HR | Purpose |
|---|---|---|
| Very Light | 50–60% | Recovery and warm-up |
| Light | 60–70% | Fat burning and endurance |
| Moderate | 70–80% | Improve aerobic fitness |
| Hard | 80–90% | Increase performance |
| Maximum | 90–100% | High-intensity training |
A healthy resting heart rate varies depending on age, physical fitness, medications, and overall health. People who exercise regularly often have lower resting heart rates because their hearts pump blood more efficiently.
| Category | Resting Heart Rate |
|---|---|
| Well-trained athletes | 40–60 BPM |
| Healthy adults | 60–100 BPM |
| Children | Higher than adults |
A resting heart rate consistently outside the expected range does not always indicate a medical problem, but persistent concerns should be discussed with a qualified healthcare professional.
Keeping track of your heart rate can help you exercise more effectively, understand your cardiovascular fitness, and avoid training too hard or too lightly. Whether you're a beginner or an experienced athlete, heart rate is a useful indicator of workout intensity.
Training within the appropriate heart rate zone helps improve endurance, cardiovascular health, and overall fitness over time.
Different heart rate zones support different fitness goals, including fat burning, endurance training, and high-intensity workouts.
Monitoring your heart rate can help prevent excessive exercise intensity that may increase fatigue and recovery time.
Temporary increases or decreases in heart rate are normal during exercise, stress, illness, or sleep. However, persistent abnormalities or symptoms should not be ignored.
Seek medical advice if you frequently experience chest pain, dizziness, fainting, severe shortness of breath, an unusually fast or slow heartbeat at rest, or irregular heart rhythms. This calculator is intended for educational purposes and should not be used to diagnose medical conditions.
For most healthy adults, a resting heart rate between 60 and 100 beats per minute is considered normal. Well-trained athletes may have lower resting heart rates.
Not always. A lower resting heart rate is common among physically fit individuals, but an unusually low heart rate accompanied by symptoms should be assessed by a healthcare professional.
Checking once daily or several times per week is usually sufficient for general fitness tracking. Athletes may monitor heart rate more frequently during training.
Yes. Emotional stress, anxiety, excitement, and even lack of sleep can temporarily increase heart rate.
No. The formula provides an estimate, but actual maximum heart rate varies between individuals.
If your heart rate feels unusually high or you experience chest pain, dizziness, or severe shortness of breath, stop exercising and seek medical advice immediately.
