Max heart rate

Max heart rate is the highest number of beats per minute your heart can achieve during maximum effort. It's estimated using the formula 220 minus your age. Knowing your max heart rate helps set training zones for optimal performance and recovery. For example, training at 70-85% of max heart rate improves cardiovascular fitness. It matters to runners for tailoring workouts to specific goals, like endurance or speed. Elite athletes often have a higher max heart rate due to better cardiovascular efficiency, while beginners may have a lower rate. Monitoring it helps prevent overtraining and reduces injury risk.
