This article explains what Zone 2 (Fat-Burning Zone) is, why it’s important for endurance and fat loss, and how to stay within this zone using FITIV. You’ll also learn how Zone 2 is calculated and where to adjust your heart rate settings for more accurate training.
What is Zone 2 in FITIV?
Zone 2 is a low-intensity heart rate range where your body mainly burns fat for energy.
It typically sits between 60–69% of your Maximum Heart Rate (MHR).
In this zone, your effort feels easy and steady. You should be able to talk without getting out of breath.
Common activities in Zone 2:
Walking
Light jogging
Easy cycling
Long steady workouts
Info: Zone 2 is often called the "fat-burning zone" because your body relies more on fat than carbs for fuel.
Why should I train in Zone 2?
Zone 2 helps you build endurance without draining your energy.
It strengthens your heart, improves efficiency, and lets you train more often with less fatigue.
Key benefits:
Better fat-burning efficiency
Stronger aerobic base
Improved cardiovascular health
Lower stress on your body
Success: Most of your weekly training should be in low aerobic zones like Zone 2 to build long-term fitness.
How do I stay in Zone 2 during a workout?
You stay in Zone 2 by watching your heart rate in real time and adjusting your pace.
Follow these steps:
Start a workout in FITIV Pulse
Watch your heart rate zones on screen
Keep your heart rate between 60–69% of Max HR
Slow down if your heart rate goes too high
Speed up slightly if it is too low
Note: If you cannot hold a conversation, you are likely above Zone 2.
Where is Zone 2 set in FITIV?
Zone 2 is automatically calculated using your heart rate settings.
FITIV uses your Maximum Heart Rate and selected training method to define your zones.
To check or adjust your zones:
Open FITIV Pulse
Go to the Profile tab
Tap Settings
Select Heart Rate Preferences
Here, you can view or edit your zones based on your fitness level.
Info: By default, FITIV estimates your Max Heart Rate using age-based formulas, but you can set your own for better accuracy.
How can I improve Zone 2 accuracy?
Accurate zones help you train at the right intensity.
Small changes to your heart rate settings can make a big difference.
To improve accuracy:
Update your Max Heart Rate
Use a known tested Max HR if available
Choose the right method (Max HR, HRR, or LTHR)
Use a reliable heart rate monitor
Warning: If your zones are wrong, you may train too hard or too easy without realizing it.
What are the best tips for Zone 2 training?
Zone 2 works best when you keep it simple and consistent.
Follow these tips:
Keep a steady and comfortable pace
Train for longer sessions, ideally 30–60+ minutes
Choose low-impact activities
Stay relaxed and avoid pushing too hard
Success: You should finish Zone 2 workouts feeling energized, not exhausted.
