What Heart Rate Zones Should You Train In?

A Fast And Easy Guide To Optimizing Your Workouts And Achieving Your Goals Through Heart Rate Zones.

What Heart Rate Zones Should You Train In?

The Cleveland Clinic states “Heart rate zones let you know how hard your heart is working and what energy source you’re using — carbohydrates or fat. The higher your heart rate gets, the more you’re relying on glycogen from carbohydrates for fuel.”
This blog post provides an informative look into heart rate zones and why they are important for your exercise routine. It explains how to calculate your maximum heart rate and how to use that information to determine your heart rate zones. We will go over each of the five heart rate zones, including the percentage of maximum heart rate associated with each zone, the type of exercises you might do in each, and the benefits of training in different heart rate zones. We will help you optimize and rework your exercise routine to achieve your fitness goals.

1. Why Are Heart Rate Zones Important?

Training in different heart rate zones can have varying effects on the body, such as improving cardiovascular fitness, building endurance, and burning fat. Aiming for a specific heart rate zone while exercising can profoundly affect your ability to reach your goals.

2. How To Calculate Your Max Heart Rate

Start by finding your max heart rate (the maximum beats per minute, BPM, that your heart can reach). An easy way to figure out your max heart rate is with this formula:  220 – (your age) = max heart rate. So, if you’re 40 years old, 220 – 40 = 180. Your max heart rate would be 180 beats per minute. After finding your max heart rate, you can start calculating your heart rate zones, or your levels of intensity.

3. What Are Heart Rate Zones?

Heart rate zones are specific BPM ranges that relate to a percentage of your max heart rate. There are 5 zones and they are used as a metric for how intensely you’re exercising. Each zone can be seen in the graphic below.

4. What Zones Should You Target?

Zone 1 (50%-60%): Also called the recovery zone, this is the least intense zone. Zone 1 is where all your day-to-day activities happen and usually isn’t targeted for training purposes. Zone 1 exercises would be walking, hiking, etc…

Zone 2 (60%-70%): Zone 2 is more intense than zone 1, but still relatively low intensity. Low-intensity exercises use fat as a fuel source rather than carbohydrates. You can comfortably remain in zone 2 for a long time, as zone 2 relies on aerobic respiration, meaning that your body will have enough oxygen to carry out the exercise. Training in this zone can help improve cardiovascular fitness and endurance, making it perfect for those looking to improve their overall fitness. Examples of zone 2 exercises would be speed walking, slow jogging, cycling, or swimming.

Zone 3 (70%-80%): Also called the threshold zone, this is a bit of a gray area. It’s not entirely aerobic and not entirely anaerobic (using glycogen instead of oxygen). Most people exercise in this zone because it feels difficult but not too difficult. If you were running a 10K race, for example, you would most likely be in zone 3. This zone is used to improve your body’s ability to process lactic acid (reduce the burning sensation) and is perfect for those looking to push their limits a little more. Zone 3 exercises would be the same as zone 2, just with more intensity.

Zone 4 (80%-90%): Zone 4 is where your body switches to anaerobic respiration and uses carbohydrates for energy. The duration of each exercise significantly drops off as your body begins producing lactic acid and a burning sensation. Training in this zone can help improve speed and power, making it perfect for those looking to take their performance to the next level. Examples of zone 4 exercises would be sprinting, plyometrics, weight lifting, or HIIT.

Zone 5 (90%-100%): Zone 5 is the highest intensity zone. It is usually only used by professional athletes who are trying to optimize their performance as much as possible. Zone 5 is not recommended for the average person, but if you want to target it, the duration of each exercise drops again as lactic acid builds up and resting time needs to be increased. Training in this zone also improves speed, power, and performance, but should be done with caution and under professional guidance as it could lead to muscle damage and injury.

5. Takeaways

Each zone has its own benefits. You can target specific zones with any smart watch that measures your heart rate. The average resting heart rate (normal heart rate) for adults is 60-100 beats per minute. Generally, the high heart rate zones will burn the most total calories. If you are trying to burn fat, low heart rate zones like zones 1 and 2 are good ways to target it without much intensity and will also improve cardiovascular health. Zones 3, 4, and 5 have increasing endurance benefits, No matter what your fitness goals are, knowing what zones to target for different purposes is a useful tool to have at your disposal.
