Target Heart Rate Calculator

This calculator estimates maximum heart rate from age, then uses resting heart rate to calculate heart rate reserve.

It uses that reserve to estimate exercise intensity zones, which can help guide cardio training.

These are general fitness estimates, not medical prescriptions.

This approach adjusts training zones based on both age and resting heart rate.

Target heart rate is the estimated heart rate range you aim for during exercise based on training intensity. It helps guide workout effort so you can train for recovery, endurance, general cardio fitness, or higher-intensity performance.

Many people search for a target heart rate calculator when they want to know their fat burn zone, cardio zone, vigorous exercise range, or safe heart rate target for walking, running, cycling, or gym training. Instead of guessing, this calculator estimates those ranges from age and resting heart rate.

Heart rate training zones can help make workouts more structured. Lower zones are often used for recovery, warm-ups, and steady endurance work. Middle zones are commonly used for moderate cardio exercise, while higher zones are more suitable for vigorous effort, speed work, and interval training.

Using heart rate zones can be helpful if your goal is to improve cardiovascular fitness, build endurance, manage workout intensity, or avoid training too hard on recovery days.

This calculator uses a heart-rate-reserve approach. First, it estimates maximum heart rate from age. Then it compares that maximum to resting heart rate to find heart rate reserve. Training intensities are then applied to estimate your target heart rate zones.

This approach is often more personalized than using age alone because it includes resting heart rate, which can reflect general conditioning and recovery status.

Heart rate reserve is the difference between maximum heart rate and resting heart rate. Once that reserve is estimated, different intensity percentages can be used to estimate moderate, vigorous, cardio, and higher-intensity training zones.

Suppose a person is 30 years old with a resting heart rate of 60 bpm. The calculator first estimates maximum heart rate, then uses heart rate reserve to estimate moderate and vigorous ranges. The result helps show a useful target zone for exercise rather than one single number.

This is why many exercisers prefer heart rate zones over a single target heart rate value. Different workouts call for different levels of effort.

Moderate target heart rate is often used for steady cardio, long-duration exercise, walking, light jogging, and general fitness sessions. Vigorous target heart rate is higher and is more commonly used for harder runs, intense cycling, interval sessions, and challenging cardio workouts.

If you are searching for moderate heart rate zone, vigorous heart rate zone, cardio heart rate zone, or fat burn heart rate, these estimates can help you choose the right effort level for your goal.

A target heart rate calculator is useful when you are planning cardio workouts, starting an exercise routine, comparing intensity ranges, or trying to train more consistently. It can also help when using a smartwatch, heart rate monitor, treadmill, bike computer, or fitness tracker.

Instead of training too easily or too aggressively, using target heart rate zones can help keep your effort better aligned with your workout purpose.
