Editor’s note: this article is the second part of a two-part series on heart health. The first part introduces the functions of the heart, the importance of taking care of it, and lifestyle changes you can make. The second part discusses why heart rate matters, how to calculate your heart rate for training, and how to incorporate it into your fitness routine.
While everyone’s fitness routine may differ, most of us tend to focus on strengthening different parts of our bodies — legs, abs, arms, glutes, etc. But what about your heart? In this article, we’ll focus on how to calculate your heart rate and why it’s essential to work out in the optimal heart rate zone.
In Chronicles of the Heart Part 1: Why Heart Health Matters, we discussed the many benefits of caring for your heart. Changes in your diet, reducing stress, and exercising were all factors that we mentioned to improve our overall health.
Now, to bring some much-needed attention to heart health, here is how to calculate your heart rate and understand the zones to help maximize your fitness routine!
While there are fitness wearables that can automatically calculate your heart rate zones for you, you can also do it yourself. All you need is a calculator, a timer, and a piece of paper.
While lying in bed, count your heart beats for one minute. Do this over three days and then use the average.
Either perform a HR max test or calculate your estimated HR max with the age calculation formula below.
This is the difference between your resting and your max heart rate.

Here’s where your health benefits start to kick in, and Zone 1 is a great place to be. While you won’t experience significant cardio benefits immediately, some research has shown that Zone 1 activities decrease disease rates and increase overall health. It’s a great intensity level for recovery days, as well.
Duration: < 90 minutes
If weight management is your goal, then Zone 2 can help. This workload is maintainable for up to 90 minutes, and it’s the lowest intensity level where your cardiovascular system can still see improvements. For long endurance training (half marathon or longer), aim for up to 80% of your training time to come from this zone.
Duration: 30–45 minutes
Zone 3 is where your body gets the most cardiovascular benefits, and it’s sometimes referred to as the aerobic zone. When it comes to developing stamina and increasing aerobic capacity, Zone 3 is where it’s at.
It’s also shown to be the most effective training zone for developing strength in weight training. For general fitness goals, Zone 3 is ideal.
Duration: 10–20 minutes
Between Zones 3 and 4, most people switch from an aerobic (with oxygen) to an anaerobic (without oxygen) energy system. This is where the level of exertion is no longer sustainable since the body becomes less efficient at producing energy from fuel sources. When it comes to boosting your performance and increasing your lactate threshold, training in Zone 4 is key.
Duration:<5 minutes
Zone 5 isn’t just for elite athletes, but caution is advised. For older adults and beginners, high-intensity training isn’t necessary. However, if you’re in good health, you may be able to do high-intensity workouts, so long as you consult a medical professional first. It can be just what you need to see an increase in your performance. Use Zone 5 for short sprints and during competitions.
When it comes to working out, heart rate training is as personal as it gets. It means that you are listening to your physiological responses during your workout and making adjustments along the way. Remember that you don’t have to run or push yourself to intense limits. Also, heart rate training helps you avoid overtraining, but it will naturally force you to progress as your fitness level gradually increases.
