One simple method to calculate your predicted maximum heart rate, uses this formula: 220 - your age = predicted maximum heart rate. Example: a 40-year-old's predicted maximum heart rate is 180 beats/minute. There are other formulas that take into account the variations in maximal heart rate with age and gender.
A normal resting heart rate is usually 60-100 beats per minute. Your number may vary. Children tend to have higher resting heart rates than adults. The maximum heart rate is, on average, the highest your pulse can get. To calculate your predicted maximum heart rate, use this formula: 220 - Your Age = Predicted Maximum Heart Rate. For example, a 40-year-old's predicted maximum heart rate is about 180 beats per minute. Your actual maximum heart rate can be determined by a graded exercise test.
