Target Heart Rate Calculator
Understanding your target heart rate is essential for maximizing the benefits of your workouts while exercising safely. Target heart rate refers to the ideal number of heartbeats per minute you should aim for during physical activity.

Read MoreYour heart beats rate, measured in beats per minute (bpm), reflects how hard your heart is working properly. It includes several key concepts like resting heart rate (RHR), maximum heart rate (MHR), and heart rate reserve (HRR), all important for targeting the right exercise intensity.
Maximum heart rate is the peak number of beats your heart can reach during intense activity. The best way to measure it is via a cardiac stress test but it can also be estimated with formulas such as the popular "220 minus age" method. Variations exist, and individual maximum heart rates can vary significantly even within the same age group.
Resting heart rate is how many times your heart beats per minute when you are calm and at rest. Typical adult ranges are roughly 50-90 bpm. Athletes often have lower resting heart beats rates, Periodically below 60.
Heart rate reserve (HRR) is the difference between your maximum and resting heart rates: HRR = MHR - RHR. It helps calculate precise target zones reflecting your personal fitness level.
Target heart rate zones are ranges that correspond to different exercise intensities and related training benefits:
- Zone 1 (50-60%): Light activity for warm-up or recovery
- Zone 2 (60-70%): Fat burning and endurance training
- Zone 3 (70-80%): Improving speed and strength
- Zone 4 (80-90%): Training max output maintenance
- Zone 5 (90-100%): Max effort to boost cardiovascular fitness but sustained briefly
The Karvonen formula uses heart rate reserve to calculate your personal target zone more accurately: Target Heart Rate = (HRR × Intensity Fraction) + RHR
You can also use subjective methods like the Borg Scale to gauge perceived effort during exercise, where individuals rate their exertion on a scale. This watchful approach complements heart rate measurements for effective training.
Knowing your personal target heart rate zones allows you to tailor workouts to your fitness goals while preventing overtraining or injury.
Whether you are a beginner or an athlete, utilizing your target heart rate can make exercise safer, more effective, and more enjoyable.
