## How do you calculate your heart rate reserve?

Calculate your heart rate reserve (HRR) by subtracting your resting heart rate from your maximum heart rate. Multiply your HRR by 0.7 (70%).

### How accurate is 220 minus age?

The traditional method by subtracting age from 220 to find maximum heart rate is less accurate than our HRmax Calculator. For older persons using “220 minus age” the estimated maximum heart rate could miss by 40 beats! Read more.

How do you calculate your maximum heart rate for exercise?

You can estimate your maximum heart rate based on your age. To estimate your maximum age-related heart rate, subtract your age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 50 years = 170 beats per minute (bpm).

How do I determine my target heart rate?

Target heart rate is generally expressed as a percentage (usually between 50 percent and 85 percent) of your maximum safe heart rate. The maximum rate is based on your age, as subtracted from 220. So for a 50-year-old, maximum heart rate is 220 minus 50, or 170 beats per minute.

## What is a good bpm for my age?

1-3 years: 80-130 bpm. 3-5 years: 80-120 bpm. 6-10 years: 70-110 bpm. 11-14 years: 60-105 bpm.

### How do you calculate moderate target heart rate?

For moderate-intensity physical activity, a person’s target heart rate should be 50 to 70% of his or her maximum heart rate. This maximum rate is based on the person’s age. An estimate of a person’s maximum age-related heart rate can be obtained by subtracting the person’s age from 220.

How to calculate heart rate for interval training?

Our HRmax Calculator calculates at which heart rate you should exercise when performing this kind of interval training. The 4×4 principle can be used in a variety of activites, including running, biking, swimming and rowing. Start with a ten minute warm-up at approximately 60 % of HRmax to get you sweating.

How to calculate your heart rate during a run?

1 Warm up thoroughly so you start sweating. 2 Do two intervals, each four minutes long. During the intervals you should be too short of breath to talk. Intersperse each interval with three minutes of active rest. 3 Start the third interval, but two minutes in, increase your speed even further an run until you’re too exhausted to continue.

## What’s the correct formula for maximum heart rate?

In The HUNT Fitness Study, we measured accurate maximum heart rate in 3,320 healthy adults aged between 19 and 89. Based on these tests we made a completely new formula which estimates maximum heart rate far more accurately than “220 minus age”. The HRmax Calculator is based on this formula: “211 – 0.64*age”.

### When does your heart rate reach a plateau?

Start the third interval, but two minutes in, increase your speed even further an run until you’re too exhausted to continue. Your HRmax will be the highest heart rate you reach. The heart will reach a plateau at which it cannot beat any faster, regardless of how much you increase the workload.
