How can one calculate their maximal heart rate for exercise?

Calculating maximal heart rate is critical for understanding appropriate exercise intensity and is typically done using a standardized formula. The most commonly accepted method is the formula that subtracts one's age from 220. This provides a general estimate of the maximum heart rate that can be achieved during exercise.

To find the target heart rate for a specific intensity, you then multiply the maximal heart rate by the desired percentage of intensity. This process allows individuals to safely gauge their exertion during physical activities and ensure they are exercising within a recommended heart rate zone for benefits such as cardiovascular improvement and weight loss.

The other options present alternative formulas, but they do not align with widely accepted practices in exercise physiology. The standard formula of (220 - age) has been validated through numerous studies and is recognized for its simplicity and reliability in providing an estimate of maximal heart rate.
