What is the maximum number of times your heart can beat in a minute?

The maximum heart rate can vary based on age and individual fitness levels, but a common formula to estimate it is 220 minus your age. For example, a 20-year-old might have a maximum heart rate of about 200 beats per minute. Highly trained athletes may achieve higher rates, but consistently reaching maximum heart rates can be dangerous and is typically not sustainable for long periods. Always consult with a healthcare professional for personalized advice.
