Target Heart Rate Calculator

Calculate your target heart rate zone for optimal exercise based on your age and fitness level. The target heart rate zone is the range of heartbeats per minute that indicates the ideal intensity level for cardiovascular exercise.

bpm (beats per minute)

Your Target Heart Rate Zones

Max Heart Rate 0 bpm
Heart Rate Reserve 0 bpm
Zone 1 (Very Light) 0-0 bpm
Zone 2 (Light) 0-0 bpm
Zone 3 (Moderate) 0-0 bpm
Zone 4 (Hard) 0-0 bpm
Zone 5 (Maximum) 0-0 bpm

Intensity Scale

  • Zone 1 (50-60%): Very light, warm-up/cool-down
  • Zone 2 (60-70%): Light, fat burning
  • Zone 3 (70-80%): Moderate, aerobic
  • Zone 4 (80-90%): Hard, anaerobic
  • Zone 5 (90-100%): Maximum, sprint

About Target Heart Rate

Your target heart rate is the range of heartbeats per minute that indicates the ideal intensity level for cardiovascular exercise. Exercising within this zone ensures you're working hard enough to improve your cardiovascular fitness but not so hard that you risk overtraining or injury.

How to Calculate Target Heart Rate

There are several methods to calculate your target heart rate zone:

  1. Traditional Method: Max HR = 220 - age. Target zone is 50-85% of max HR.
  2. Tanaka Method: Max HR = 208 - (0.7 × age). More accurate for older adults.
  3. Karvonen Method: Uses resting heart rate to calculate Heart Rate Reserve (HRR). Target zone is (HRR × intensity%) + resting HR.
  4. Zoladz Method: Defines 5 zones based on percentages of max HR for different training effects.

Why Target Heart Rate Matters

Exercising at the right intensity is crucial for achieving your fitness goals:

Understanding Heart Rate Zones

Zone 1 (50-60% of max HR): Very light activity, good for warm-ups, cool-downs, and recovery. Improves basic endurance and fat metabolism.

Zone 2 (60-70% of max HR): Light activity where you can carry on a conversation. Ideal for fat burning and building aerobic endurance.

Zone 3 (70-80% of max HR): Moderate activity where breathing becomes heavier. Improves aerobic capacity and endurance.

Zone 4 (80-90% of max HR): Hard activity where talking becomes difficult. Increases anaerobic threshold and performance.

Zone 5 (90-100% of max HR): Maximum effort, unsustainable for long periods. Improves speed and power.
