What is Zone 2 Cardio?

There are many kinds of cardio workouts, but they all have one essential element in common: They get your heart pumping. In fact, the term "cardio" is derived from "cardiovascular," which reflects its primary function of raising your heart rate. However, cardio workouts also increase your breathing and blood flow. Over time, this helps to enhance your body's aerobic capacity—its ability to use oxygen more efficiently during exercise.

What is Zone 2 Cardio?

The intensity at which you get your heart pumping defines the zones. Zone 1 is the slowest, which makes Zone 5 (you guessed it!) the highest. Determining your personal zones begins by identifying your maximum heart rate. According to the Cleveland Clinic¹, your maximum heart rate is 220 minus your age. So, for example, at age 30, your maximum heart rate would be 190 bpm (beats per minute).

Zone 2 corresponds to 60%-70% of your maximum heart rate. You can calculate this by multiplying your maximum heart rate by 0.6 for the low end and by 0.7 for the high end.¹

Knowing which zone you're working in is crucial as it also reveals what you're using for energy. As your heart rate increases through the zones, you burn more carbohydrates and proteins and less fat.²

Why Should Someone Do Zone 2 Cardio?

Zone 2 cardio, also known as “base cardio,” is generally a good starting pace, and one many people return to during their exercise routines. It’s typically a steady effort that you can maintain while talking intermittently with friends or singing along to your music. Zone 2 is a step up from a stroll, more like a gentle jog.

In Zone 2, your body is fueling itself with about 65% fat and only 35% carbs and protein.² It’s also a crucial part of endurance training, since you should ideally be able to maintain it for long periods.

Another benefit of Zone 2 cardio is its health impacts. A 2003 study³ found that moderate exercise training for three months decreased blood pressure and heart rate, and improved the heart's ability to adapt to changing circumstances and needs.

In short, Zone 2 cardio helps you burn fat and build your body’s fitness, regardless of the type of exercise you prefer.

Ways to Do Zone 2 Cardio

Fortunately, there are many options for getting your heart into that key Zone 2 range. Prime examples include:

• Cycling—There’s no set speed or distance that works for everyone; push yourself just a little and check your pulse to stay in the zone⁴
• Jogging—A steady pace with a low-to-moderate, sustainable effort⁵
• Rowing—A low-intensity workout that raises your heart rate just a bit⁶
• Rollerblading or roller skating—A low-impact method that is easy to maintain in the Zone 2 sweet spot with a lower chance of pushing too hard⁷
• Swimming—A moderate, sustainable pace, making it another excellent choice for getting your heart pumping without worrying about overdoing it⁸
• Pickleball—This game’s fun, social pace may be just what you need for your Zone 2 cardio!

Walking does not typically count as Zone 2 cardio, but jogging does. Remember, it should elevate your heart rate to 60-70% of your maximum range but still be low-fatigue. Zone 2 shouldn’t cause difficulty in catching your breath. If you can't chat a bit with your workout partners, you’ve probably pushed up into Zone 3 or 4.²
