The 2025 Fitness Trend You Can’t Ignore: Zone 2 Cardio for Fat Burn & Endurance

 What Is Zone 2 Cardio?

Zone 2 cardio is the sweet spot where your body uses fat as the main energy source instead of carbs. It’s moderate, sustainable, and incredibly effective for long-term fat loss and heart health,  which is why U.S. fitness enthusiasts are searching for it more than ever in 2025.

Your Zone 2 heart rate is typically around 60–70% of your maximum heart rate.
You should be able to hold a conversation but not sing.

 Why Zone 2 Training Works Better Than HIIT (for Most People)

While HIIT workouts are still popular, many are switching to Zone 2 because:

• It’s easier to recover from
• Burns more fat over time
• Improves endurance and energy efficiency
• Boosts mitochondrial health (the body’s energy factories)
• Can be done daily without exhaustion

 How to Know You’re in Zone 2

Use this simple formula:
(220 - your age) × 0.6 to 0.7 = Zone 2 range

Example: If you’re 30 years old → (220 - 30) × 0.6 = 114 bpm (bottom)
and (220 - 30) × 0.7 = 133 bpm (top).

So, keep your heart rate between 114–133 bpm during your workout.
