How to calculate max heart rate?

To calculate your maximum heart rate, a commonly used formula is 220 minus your age. For example, if you are 50 years old, you would calculate your max heart rate as 220 - 50, which equals 170 beats per minute. However, this formula provides a rough estimate and individual maximum heart rates can vary. It is not an absolute indicator of fitness, as some very fit people might have lower maximum heart rates and others who are less fit might have higher maximum heart rates. The formula is a starting point, and for more precision, you might consider using a heart rate monitor during an intense workout to find your actual maximum heart rate 12.
