What is the formula used to estimate maximum heart rate (HRmax)?

220 - age
200 - age
210 - age
215 - age

The correct answer is: 220 - age

The formula used to estimate maximum heart rate (HRmax) is 220 minus age. This formula is widely accepted in exercise science and is based on population data that provides an average maximum heart rate for individuals of varying ages. As a person ages, their maximum heart rate tends to decrease, and this formula gives a quick estimate that can be useful for determining exercise intensity during aerobic activities. Using this formula helps trainers and individuals establish heart rate zones for training, ensuring that workouts are effective and safe. While there are other methods and variations for calculating HRmax that may provide different estimations, the 220 minus age formula remains the simplest and most commonly referenced guideline in many fitness programs.
