# Target Heart Beat Calculator

Target pulse Rate / Heart Beat Calculator calculates a very close approximation of a targetted maximum heartbeat to be monitored during exercise. By this calculator, you can monitor the heartbeat rate during exercise depending on your age.

Ever ask yourself, "how do I find my target heart rate?" Finding your target heart rate is easy with our target heart rate calculator. Target heart rate calculation can be determined for any age and activity level, enabling you to use a heart rate monitor and get the most benefit from your workouts.

It is recommended that you exercise within 55 to 85 percent of your maximum heart rate for at least 20 to 30 minutes to get the best results from aerobic exercise. The MHR (roughly calculated as 220 minus your age) is the upper limit of what your cardiovascular system can handle during physical activity.

### Calculator of Target Heart Beat

Target Heart Rate (THR) range values are often calculated to ensure exercise intensity is maintained at a desired level. This calculator automatically calculates THR ranges.

The Karvonen formula is often used for this purpose and calculates results as a function of heart rate reserve (HRR) and maximum heart rate (HRmax).

HRR = HRmax - HR rest

Where HRrest is the resting HR of the individual

HRmax may be calculated by a maximal exercise test (value to be entered into the calculator directly) or by using an age predicted formula.

There are two formulae currently favoured:

1. HRmax = 220 – age (which is reported to be simpler to use)
2. HRmax = 206.9 – (0.67 x age) (reported to be more accurate

Target HR range is calculated as follows:

THRR = (HRR x desired training intensity) + HRest

Target HRmax (THRmax) is caluclated as follows:

THRmax = (desired training intensity) x (HRmax)

For example, if calculating THRR for a 45 year old with a resting HR of 72 bpm, whereby training intensity is 40-59 %:

HRR = [(220 – 45) – 72] = 103 bpm
THHR = 103 * 0.4 + 72 = 113.2 bpm and 103 * 0.59 + 72 = 132.77 bpm
THHR = 113 – 133 bpm

Knowing how hard you need to exercise helps you reach your goals more quickly. It also ensures that you don't push your body too much, making exercise unsafe. Working out in a target heart rate zone can help ensure your workout is safe and beneficial.

Cardiovascular exercise relies on frequency, intensity, and duration to be effective. You know how often you exercise and for how long, but you need to know your heart rate to judge your intensity. Learn more about the effects of each of the five heart rate zones and how to use them in your cardio workouts.

#### What Is Heart Rate?

Your heart rate is the number of beats your heart completes each minute. Heart rate is also known as pulse and is what you feel when you press your wrist or neck to check your pulse. Your heart rate changes constantly based on what you are doing. It changes with physical activity and in response to an emotional stimulus such as excitement or anxiety.

#### Resting Heart Rate

Resting heart rate (RHR) is the number of beats per minute your heart completes when you are completely at rest. It is the lowest rate your heart usually beats since you are not being active. This rate should be measured when you are resting (sitting or lying down), without any emotional stimulus or illness influencing the rate. A normal resting heart rate for an adult is considered to be between 60 and 100 beats per minute (bpm).

#### Maximum Heart Rate

Maximum heart rate (MHR) is as fast as your heart can beat. One way to estimate it is 220 minus your age (so if you are 35 years old, your MHR is 185). However, this is just a guess, and your actual maximum heart rate is likely different.

#### Target Heart Rate

Target heart rate is a goal of how fast you want your heart rate to be while exercising. It helps indicate the intensity you are working. Your estimate for your target heart rate is just a guess, but it gives you an idea of how hard you work during exercise. Your target heart rate will depend on your current fitness level and age, which means it will change as your cardiovascular endurance increases or as you get older.

#### How to Find Your Target Heart Rate

This calculator uses a simple age-graded estimation of your MHR. Then, the chart below multiplies it by your chosen percentage to show various target heart rate zones.

### Maximum Heart Rate Formula

206.9 - (0.67 x age)

This and other MHR prediction equations are the subjects of ongoing research since they tend to underestimate the MHR for people over age 30.3.

That means that if you are older than 30, it may be more accurate to use +11/-11 deviation from the number as a more acceptable range.

So if you are 35 years of age with a maximum heart rate of 183 (calculated using the formula above), the estimate would be between 172 to 194. The maximum heart rate may be a little higher for women and older adults.

Some fitness trackers or smartwatches automatically measure your resting heart rate and then use that information to suggest and measure the target heart rate. An advantage of using these devices to find your target heart rate is that the manufacturer can easily update them to match the current research-backed zones.

#### How to Use Heart Rate Zones

When it comes to heart rate zone training, you can mix it up and enjoy moderate-intensity exercise on some days and vigorous on others. You get different fitness benefits by exercising in different heart rate (HR) zones. In each zone, you will feel a different level of exertion.

### Low-Intensity Zone

Working at 57% to 63% of your maximum heart rate means you are in the low-intensity zone. Exercising at this intensity can help relieve stress5 and reduce the health risks associated with a sedentary lifestyle. Low-intensity exercise can boost your mood, lower blood pressure, improve endurance, and is excellent for cardiovascular health.

Training within this zone is beneficial if you recover from a more intense exercise session. Many forms of flexibility and strength exercises are also lower intensity, but they are still crucial for your muscles and physical condition.

Low-Intensity Exercise Options
Yoga (especially restorative or Hatha yoga)
Pilates
Mobility and flexibility training
Walking (2.0 to 2.9 miles per hour)

### Moderate-Intensity Zone

Moderate-intensity training is performed at 64% to 76% of your maximum heart rate. This intensity level is typically recommended for building fitness and burning calories for weight balance. For health and fitness benefits, aim to exercise in the moderate-intensity zone for 30 minutes per day, five days per week for at least 150 total minutes per week.

The Physical Activity Guidelines for Americans recommend up to 300 minutes (5 hours) per week for additional benefits.

Moderate-intensity exercise improves oxygen transportation throughout your body, boosting heart health.

Moderate-Intensity Exercise Options
■ Brisk walking
■ Strength training
■ Swimming
■ Cycling (under 10 miles per hour)
■ Jogging

### Vigorous-Intensity Zone

You are training in the vigorous-intensity zone at 77% to 95% of your maximum heart rate. The physical activity guidelines recommend 75 minutes of vigorous activity per week.Alternatively, you can perform moderate and vigorous activity for up to 150 minutes, which will likely be easier to sustain and recover from.

This zone spurs your body to improve your circulatory system by building new blood vessels and increasing your heart and lung capacity. Exercising at the high end of this range (84% MHR or higher) will improve the amount of oxygen you can consume - your VO2 max.

This exertion level takes you to the limit where your body begins to produce lactic acid. Runners, cyclists, and racewalkers use this zone to build their ability to go even faster.

Vigorous-Intensity Exercise Options
■ Running
■ Cycling (over 10 miles per hour)
■ Lap swimming
■ Strength training (with short rests and/or heavy weights)
■ Plyometric and explosive training

### Maximum-Intensity Zone

You are pushing as hard as possible at the maximum-intensity level (96% to 100% of your MHR), such as with high-intensity interval training or sprinting. You can't work any harder. Most people can't stay in this zone for more than a few minutes. You will be unable to speak except for gasping single words.

Consult your doctor to ensure you can safely work out at such a high heart rate. This zone should only be used for short bursts during interval training, where you work intensely for a minute, then drop back down to a lower intensity for several minutes, then repeat.

Maximum-intensity exercise can be very effective for improving your cardiovascular capacity and the ability to clear lactic acid. This has carryover for improvements in the other intensity zones.

### How to Monitor Your Heart Rate Zone

Take your heart rate five minutes after the start of your exercise session and retake it before you go into your cool down. You can do this by taking your pulse or using a heart rate monitor, fitness tracker, or smartwatch.

You can find your pulse at your neck (carotid artery) or wrist (radial artery). You will need a timing device that shows seconds, so switch to stopwatch mode on your smartphone clock or use a watch, clock, or timer with a second hand.

• Use two fingers (not your thumb, which has a pulse). It is often easiest to find your pulse in the carotid arteries on either side of your windpipe. Start feeling for it just beneath your jaw, next to your windpipe.
• Once you locate the pulse, press lightly, count your pulse for 10 seconds and multiply by six, or count for 15 seconds and multiply by four. So 20 beats for 10 seconds = 120 beats per minute; 20 beats for 15 seconds = 80 beats per minute.
• You may need to stop to do this at first, but once you can locate it, try to keep walking slowly or marching in place while taking your pulse to keep it from slowing.

Many treadmills and other exercise machines have grips with pulse sensors built in. You grip them, and your pulse will read out on display on the machine. You usually will not have to interrupt your workout to get a reading. You can also use a mobile app.

#### Use a Heart Rate Monitor

Heart rate monitors with a chest strap are more accurate than taking your pulse. They transmit the data to a wrist unit or a mobile app so you can see your heart rate throughout your workout.

As prices increase, models include many other features, such as tracking your heart rate zones, stopwatch features, calories burned, and more. Different heart rate monitors have pulse monitors where you place one or two fingers on a sensor for a reading.

Many heart rate monitors offer the ability to pre-program multiple heart rate zones. This is beneficial if you do different intensity workouts because you won't have to reprogram it each time. Some will even tell you how long it takes to return to your resting heart rate.

#### Use a Fitness Tracker or Smart Watch

Some fitness trackers and smartwatches, such as some models of Fitbit and the Apple Watch, have LED pulse sensors on the underside next to the skin. These must be worn securely against the skin to get a stable and accurate reading.

To save battery life, many of them don't read continuously. See the instructions for your device to see how to get an on-demand or continuous pulse reading.

These devices often have simplified heart rate zones, such as light, moderate, and vigorous. Some allow you to set a target heart rate and have a visual or auditory alert when you are in your chosen zone.
