What does the formula 220 minus your age tell you?

The formula 220 minus your age is commonly used to estimate your maximum heart rate during exercise. This calculation helps determine the appropriate heart rate zones for cardiovascular workouts. For instance, if you're 30 years old, your estimated maximum heart rate would be 190 beats per minute (220 - 30 = 190), which can guide your training intensity. It's important to note that individual variations can exist, so consulting a healthcare professional for personalized advice is recommended.
