Heart Rate Zone Calculator

Calculate your maximum heart rate and 5 training heart rate zones based on age. Ideal for running, cycling, swimming, and other cardio training intensity planning.

5 Training Zones

What are Heart Rate Zones?

Heart rate zones are ranges of beats per minute (bpm) that correspond to different exercise intensities. Training within specific zones helps optimize your workout results, such as fat burning, endurance improvement, or speed enhancement.

Z1

Warm Up / Recovery

Low intensity, ideal for warm-up and recovery training

50-60%
Z2

Fat Burn

Moderate intensity, primarily burns fat for energy

60-70%
Z3

Aerobic Base

Moderate-high intensity, improves cardiovascular fitness and endurance base

70-80%
Z4

Anaerobic Threshold

High intensity, near anaerobic threshold for speed endurance

80-90%
Z5

VO2 Max

Maximum intensity for developing VO2 max and explosive power

90-100%

How do I calculate my maximum heart rate most accurately?

220 minus age is the most commonly used estimation formula, but individual variation exists. The most accurate method is through professional cardiopulmonary exercise testing to measure your actual maximum heart rate. The Tanaka formula (208-0.7×age) may be more accurate for middle-aged and older adults.

Which zone should I train in?

It depends on your training goals. Zone 2 (60-70%) is ideal for fat burning and base endurance; Zones 3-4 (70-90%) improve cardiovascular function and speed; Zone 5 (90%+) is for short high-intensity sprint training.

Which zone should beginners start with?

Beginners should start with Zone 2 (60-70% of max HR), aiming for 20-30 minutes per session. At this intensity you can hold a conversation while effectively burning sugar and fat without excessive fatigue.
