Zone 2 Cardio, Without the Jargon

Every podcast is talking about Zone 2 — and for once the hype is mostly right. It's the easy, conversational cardio that quietly builds your engine.

What "Zone 2" means

It's low-intensity cardio at roughly 60–70% of your max heart rate. The simplest test: you can hold a conversation but not sing. That's the pace.

Why it's worth it

How to do it

Brisk walking, incline treadmill (12-3-30 is perfect), easy cycling or jogging. Aim for 2–4 sessions of 30–60 min a week.

Don't overthink "fat-burning zone." Zone 2 burns a higher percentage of fat, but total fat loss still depends on your overall calorie deficit.
