Let’s get one thing straight: you don’t need to sprint or suffer to slim down.
In fact, walking at the right pace might be the smartest way to burn fat. The secret? It’s called Zone 2 cardio. This sweet spot burns fat efficiently, improves endurance, and doesn’t leave you gasping for air.
In this post, we’ll break down exactly how to use walking to tap into Zone 2 and get leaner without wrecking your knees or your schedule.
What Is Zone 2 Cardio, Really?
Zone 2 cardio is your body’s “cruise control” mode. It’s a moderate level of effort where your body uses fat for fuel instead of carbs. Technically, it’s around 60 to 70 percent of your max heart rate.
Here’s a cheat code: subtract your age from 220. Multiply that number by 0.6 and 0.7. That’s your heart rate range for Zone 2.
Example: If you’re 40, Zone 2 is roughly 108 to 126 beats per minute.
Why does this matter? Because staying in Zone 2 helps train your body to use fat as a primary energy source — the holy grail for fat loss.
Why Walking Works So Well
Most people think they need to crush HIIT workouts to lose fat. Not true.
Walking is:
Low impact
Easy to recover from
Accessible anywhere
Surprisingly effective at keeping you in Zone 2
Running can spike your heart rate past Zone 2 quickly. Walking? Much easier to stay in that optimal fat-burning zone.
How to Know If You’re in Zone 2 While Walking
Forget guessing. Use these methods to stay in the fat-burning zone:
1. Talk Test: You should be able to hold a conversation, but not sing.
2. RPE (Rate of Perceived Effort): On a scale of 1 to 10, aim for a 4 to 6.
3. Heart Rate Monitors: Devices like Apple Watch, Garmin, and Polar can track your heart rate in real time. Stay within your calculated range.
Too fast and you start burning sugar, not fat. Too slow and you’re just strolling. Find your zone.
