Maximal Heart Rate (MHR)

Maximal Heart Rate (MHR) is the highest number of times your heart can beat per minute during intense exercise. It varies from person to person and decreases with age. Knowing your MHR helps determine safe and effective exercise intensity levels, ensuring you train within an optimal range for cardiovascular fitness. Typically, MHR is estimated using formulas like 220 minus your age, but individual differences mean that an exercise stress test can provide a more accurate measurement. Monitoring your heart rate during activity helps you stay within your target zone, maximizing benefits while reducing risk.
