Heart Rate Insights

Understanding fatigue during exercise goes beyond just breathlessness; it encompasses various physical sensations like leg burning or lightheadedness. The concept of heart rate zones can be misleading, as they are often generalized and not tailored to the individual. A more accurate approach is to identify your maximum heart rate, which can be roughly calculated using the formula 220 minus your age. This personalized metric provides a clearer picture of your exertion levels.
