What does 'RHR' stand for in the target heart rate formula?

The term 'RHR' in the context of the target heart rate formula stands for Resting Heart Rate. This is a crucial measurement that represents the number of times your heart beats per minute when you are at rest. Knowing your resting heart rate is important because it can provide insight into your overall cardiovascular fitness and health.

When calculating your target heart rate for exercise, the resting heart rate is often subtracted from maximum heart rate to find the range that is most beneficial for improving cardiovascular fitness. This formula helps individuals gauge what intensity level they should aim for during their workouts to maximize exercise benefits efficiently and safely. Understanding your resting heart rate is essential for setting a personalized target that aligns with your fitness goals.
