The short version
- “Zone 2” is a popular name for steady, easy-to-moderate aerobic exercise.
- You can find it with the talk test: you can speak in sentences, but not sing.
- Brisk walking, easy cycling, easy swimming and light jogging all count.
“Zone 2” is not an official government term. It comes from heart-rate zone systems that split intensity into bands. Zone 2 usually means the low end of moderate intensity: steady, comfortable, sustainable.
How to find it
- Talk test: the CDC describes moderate intensity as being able to talk but not sing.
- Effort scale: about 5 on a 0 to 10 scale. See RPE.
- Heart rate: the American Heart Association places moderate intensity at about 50 to 70% of your estimated maximum heart rate (220 minus your age). Estimates vary from person to person.
Why people like it
It is easy to recover from, so you can do a lot of it. That helps you reach the guideline of 150 to 300 minutes of moderate activity per week.
Do this today
Go for a 20-minute brisk walk at talk-test pace: you can talk, but singing would be hard.
