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
Your actual maximum heart rate can be determined by a graded exercise test. If you are taking medicines or have a medical condition, ask your doctor if your maximum heart rate (and target heart rate) should be adjusted.
You gain the most benefits when you exercise in your "target heart rate zone." Usually, this is when your exercise heart rate (pulse) is 60%-80% of your maximum heart rate. In some cases, your doctor may decrease your target heart rate zone to begin with 50%.
