The 5 Cardio Zones Explained

Cardio heart zones are, essentially, levels of exertion as measured based on a percentage of your maximum heart rate. Many wearable fitness devices and apps can easily measure this for you, such as the Zones app for the Apple Watch.

Knowing which cardio zone to target when you engage in cardiovascular activity will ensure your workout is effective and safe. It can also help you judge the intensity of your workout and keep you on track toward your goals. In this article, we outline the five cardio zones so you can choose the one that makes sense for you.

What are the five cardio zones?

Cardio Zone 1

This is the chill zone of working out. Think about those super easygoing activities – like doing some gentle yoga, light stretching or just going for a nice, easy walk. It’s all about keeping your heart rate down to about 57% (or even less) of the max it can go. This means you’re taking it easy, staying cool, and definitely not sweating buckets.

When you’re in this zone, you’re keeping things super laid-back. It’s perfect when you’re just getting started on getting fit, taking it easy after being sick or hurt, or on those days when you feel like moving but not going all out. The best part? You can chat with a friend, enjoy the scene, and not run out of breath.

And just because it’s easy doesn’t mean it’s not doing you good. These light workouts are awesome for keeping your body moving, keeping those joints happy, and helping you chill out. Plus, they set the stage for you to step it up when you’re ready for more action.

Even if you’ve got some aches, or just new to this whole exercise thing, these low-key moves are your best buds. They let you get some exercise without pushing too hard or risking a hurt.

So, this zone? It’s not about pushing limits. It’s about being kind to your body, giving yourself some love, and enjoying moving at your own pace. Sure, it’s calm, but it’s still mighty good for your health, heart, and peace of mind.

Cardio Zone 2

This second cardio zone, which falls between 57 and 63% of your maximum heart rate, is the most beneficial. This zone involves moderate movement that you can perform comfortably for 30-60 minutes. You’ll likely break a good sweat, but will not feel wiped out.

Working in zone 2 cardio has many health benefits including improved heart health, enhanced brain health, and reduced risk of age-related diseases.

Cardio Zone 3

The third zone involves vigorous aerobic activity, such as running, and it is about 64-76% of your maximum heart rate. In the zone 3 cardio, you’ll find it’s challenging to maintain a conversation.

Cardio Zone 4

Dialing It Up: The High Energy Zone and Its Effects 🚀

When you hit Zone 4, you’re entering the territory of challenging workouts, where your heart rate soars to between 77 and 95% of its maximum capacity. This level of intensity is typically achieved through things like high-intensity interval training (HIIT). It’s a fast-paced, sweat-inducing session that can seriously boost your fitness levels. Yet, it’s important to be aware of the flip side – potential muscle damage and Delayed Onset Muscle Soreness (DOMS), making you more prone to aches and possible injuries.

But fear not, it’s not all extreme! To safely experience Zone 4, consider using a rowing machine. It gets your heart rate up without the same risk of injury that high-impact activities might pose. Rowing is a full-body workout that blends cardiovascular challenge with strength elements, making it a safer bet for intense training. For a thorough guide to rowing, you might find Harvard Health Publishing’s article helpful.

Listening to your body is crucial, especially when flirting with your upper heart rate limits. Before jumping into advanced workouts like HIIT, it could be beneficial to consult with a fitness expert. The American Council on Exercise has a great resource on high-intensity workouts that can help you stay safe while getting fit: High-Intensity Workouts.

Cardio Zone 5

Zone 5 is maximum effort. This is performing the 100-meter sprint, all-out. At Nielsen Fitness, we don’t advise this cardio zone. It’s usually reserved for elite athletes; for weekend warriors or the average person, the risks far outweigh the benefits. So our advice, is to stay away from a zone 5 cardio heart zone.
