Understanding Your Zones

Your heart rate zones help you train at the right intensity for your goals.

  • Fat Burn Zone: Best for long, easy workouts. Burns a higher percentage of fat for fuel. Good for beginners and recovery days.
  • Cardio Zone: Improves heart and lung fitness. You can talk but not sing. Great for building endurance.
  • Peak Zone: High-intensity training for short bursts. Improves speed and power. Difficult to maintain for long.
