What is Heart Rate Zone Training?

Heart rate zone training is a method of structuring your cardio workouts based on different intensity levels, each targeting specific physiological adaptations. By training in specific heart rate zones, you can optimize your workouts for different goals like fat loss, endurance, or performance.

Benefits of heart rate zone training:

  • Provides objective intensity measurement
  • Helps prevent overtraining and burnout
  • Optimizes training for specific goals
  • Tracks fitness progress over time

Calculate Your Heart Rate Zones

Use our heart rate zone calculator to determine your personalized training zones based on your age, fitness level, and goals.

Calculate Heart Rate Zones

The 5 Heart Rate Zones

Zone 1 - Recovery

50-60%

Very light intensity for active recovery

Feel: Easy, can hold conversation•Duration: 20-60 minutes
Improves circulation
Speeds recovery
Builds aerobic base

Zone 2 - Aerobic Base

60-70%

Moderate intensity for building aerobic capacity

Feel: Comfortable, can talk in sentences•Duration: 30-90 minutes
Builds aerobic base
Burns fat efficiently
Improves endurance

Zone 3 - Aerobic

70-80%

Moderate to high intensity for aerobic fitness

Feel: Moderate effort, short sentences•Duration: 20-60 minutes
Improves aerobic capacity
Increases lactate threshold
Builds stamina

Zone 4 - Threshold

80-90%

High intensity at lactate threshold

Feel: Hard effort, few words•Duration: 10-30 minutes
Raises lactate threshold
Improves race pace
Builds mental toughness

Zone 5 - VO2 Max

90-100%

Maximum intensity for VO2 max training

Feel: Very hard, cannot talk•Duration: 3-8 minutes
Increases VO2 max
Improves speed
Builds power

Heart Rate Calculation Methods

Karvonen Formula

High

Most accurate method using resting heart rate

Target HR = ((Max HR - Resting HR) × %Intensity) + Resting HR

Age-Based Formula

Moderate

Simple method using age only

Max HR = 220 - Age

Tanaka Formula

Good

More accurate age-based formula

Max HR = 208 - (0.7 × Age)

Heart Rate Monitoring Tips

Use a Heart Rate Monitor

Invest in a chest strap or wrist-based monitor for accurate readings during exercise.

Check Resting Heart Rate

Measure your resting HR first thing in the morning for baseline calculations.

Listen to Your Body

Use perceived exertion alongside heart rate for better training guidance.

Track Progress

Monitor how your heart rate responds to the same workout over time.

Start Training with Heart Rate Zones

Now that you understand heart rate zone training, calculate your personalized zones and start optimizing your cardio workouts for better results.
