Introduction:

Your heart rate — the number of times your heart beats per minute — is one of the simplest windows into your cardiovascular health. It changes constantly throughout the day: lower when you’re resting or asleep, higher when you’re active, stressed, or excited. But what counts as “normal” depends heavily on context — your age, your fitness level, and whether you’re sitting still or exercising.

Most people check their heart rate in one of two situations: to see if their resting heart rate (the number when calm and inactive) falls within a healthy range, or to figure out their target training zones for exercise — the heart rate ranges that correspond to fat burning, cardio conditioning, or peak effort.

The MyHealthChart Heart Rate Chart brings both of these together in one tool, using the same American Heart Association (AHA) guidelines and standard exercise physiology formulas used by trainers and doctors — so you get a clear, instant answer either way.

How to Use the Heart Rate Chart:

The tool has two modes, switchable with a single tap at the top:

Resting Heart Rate Checker:

  • Measure your resting heart rate — ideally first thing in the morning, before getting out of bed, or after sitting quietly for several minutes.
  • Enter your age into the first field.
  • Enter your resting heart rate (in beats per minute, or bpm) into the second field.
  • Click “Check Resting Heart Rate” — your result appears instantly with a category badge (Low, Normal, Elevated, or High).
  • Scroll down to the reference chart — your matching age group automatically highlights, so you can compare your number to both general and athlete ranges.

Target Training Zones:

  • Switch to the “Target Training Zones” tab.
  • Enter your age.
  • Click “Calculate My Training Zones” — the tool estimates your maximum heart rate and breaks it down into five training zones, each with its own bpm range.

No data is stored or saved in either mode — you can recalculate as many times as you like.

The Method Behind the Calculations:

Resting Heart Rate Categories:

For most healthy adults, a resting heart rate between 60–100 bpm is considered normal, though well-conditioned athletes often sit lower — sometimes as low as 40 bpm — because a stronger heart pumps more blood per beat and doesn’t need to beat as often.

CategoryResting Heart Rate (bpm)
Low (Bradycardia range)Below 60 (below 70 for children)
Normal60 – 100
Elevated101 – 110
High (Tachycardia range)Above 110

Maximum Heart Rate & Training Zones:

The calculator uses the most widely used estimation formula in exercise science:

Maximum Heart Rate = 220 − Age

Zone% of Max HRPurpose
Warm Up50–60%Light activity, warming up muscles
Fat Burn60–70%Steady, lower-intensity calorie burning
Cardio (Aerobic)70–80%Building cardiovascular endurance
Hard (Anaerobic)80–90%High-intensity conditioning
Peak / Maximum90–100%Maximum effort, short bursts only

For a 30-year-old with a max HR of 190, the Fat Burn zone would be roughly 114–133 bpm, while the Peak zone would be 171–190 bpm.

Tips for Getting Accurate Results:

  • Measure resting heart rate before caffeine, exercise, or stress — all three can temporarily raise your pulse and skew your reading.
  • Use two fingers (not your thumb) on your wrist or neck to check your pulse manually, and count for a full 60 seconds for the most accurate result, or use a heart rate monitor or smartwatch.
  • Take your resting reading at the same time each day if you’re tracking trends — most people get the most consistent number first thing in the morning.
  • Remember the 220 − Age formula is an estimate, not a measured value. Actual maximum heart rate can vary by 10–15 bpm in either direction depending on genetics and fitness level.
  • Don’t push to your true maximum heart rate to “test” it — this can be dangerous without medical supervision. The formula exists specifically so you don’t have to.
  • Use training zones as a guide, not a rulebook. Talking comfortably means you’re likely in the Fat Burn zone; being unable to speak in full sentences usually means you’ve crossed into Hard or Peak.
  • If you take heart-rate-affecting medication (such as beta-blockers), your actual max heart rate and zones may be lower than the formula suggests — ask your doctor for a personalized range

Reading Your Results & Chart Guide:

Resting Heart Rate Results:

🔵 Low (Bradycardia Range)
A resting rate below 60 bpm (or below 70 in children) can be completely normal in athletes, but in others it may cause fatigue, dizziness, or fainting. If you experience symptoms alongside a low reading, speak with a doctor.

🟢 Normal
A resting rate between 60–100 bpm reflects healthy, typical heart function for most adults. Generally, the lower end of this range (closer to 60) is associated with good cardiovascular fitness.

🟡 Elevated
A resting rate of 101–110 bpm is worth monitoring. This can be caused by stress, dehydration, caffeine, lack of sleep, or early signs of overtraining — but is usually not an emergency on its own.

🔴 High (Tachycardia Range)
A consistent resting rate above 110 bpm should be discussed with a doctor, especially if accompanied by symptoms like chest discomfort, shortness of breath, or palpitations.

Training Zone Results:

Each of the five zone cards shows your personalized bpm range, color-coded from light blue (Warm Up) through to red (Peak). These ranges help you train with purpose — staying in the Fat Burn zone for longer, steady workouts, or pushing into Cardio and Hard zones for shorter, higher-intensity sessions.

Important Limitations to Keep in Mind:

This tool provides estimates based on standard formulas, not personalized medical measurements. The 220 − Age formula for maximum heart rate is a population average — individual results can vary significantly, especially in highly trained athletes or people with certain heart conditions.

Resting heart rate can also be temporarily affected by illness, dehydration, medication, anxiety, and even room temperature. A single abnormal reading isn’t a diagnosis — but a consistent pattern across multiple days, especially alongside symptoms, is worth discussing with a doctor.

If you have a known heart condition, are pregnant, or are new to exercise, consult a doctor before using target heart rate zones to guide workout intensity.

Heart Rate Calculator FAQs

Common questions about Heart Rate Calculator, answered in simple words:

1. What is a normal resting heart rate according to MyHealthChart?

According to MyHealthChart‘s Heart Rate Chart, a normal resting heart rate for most adults falls between 60 and 100 bpm. Well-conditioned athletes often sit lower than this range, sometimes as low as 40 bpm, since a stronger heart doesn’t need to beat as often.

My HealthChart uses the standard exercise science formula, Maximum Heart Rate = 220 − Age, to estimate your max heart rate. From there, MyHealthChart breaks it down into five zones — Warm Up, Fat Burn, Cardio, Hard, and Peak — each shown as a percentage range of your estimated maximum.

The formula used by MyHealthChart is a widely accepted estimate, not a measured value. Actual maximum heart rate can vary by 10 to 15 bpm depending on genetics and fitness level, so MyHealthChart‘s training zones should be used as a guide rather than an exact rule.

If MyHealthChart categorizes your resting heart rate as High (Tachycardia range) or Low (Bradycardia range), this isn’t a diagnosis on its own. However, if the reading is consistent across multiple days, or you experience symptoms like dizziness, chest discomfort, or shortness of breath, MyHealthChart recommends speaking with a doctor.

If you take medication that affects heart rate, such as beta-blockers, your actual maximum heart rate may be lower than what MyHealthChart’s formula estimates. In this case, MyHealthChart recommends asking your doctor for a personalized target heart rate range instead.

No. MyHealthChart calculates your resting heart rate category or training zones instantly in your browser and does not store, save, or share any of the numbers you enter. You can use the MyHealthChart Heart Rate Chart as many times as you like with no sign-up required.
