How To Calculate Your Target Heart Rate

What is a "target heart rate", and how do I calculate mine?

Your target heart rate is the heart rate you are looking to accomplish in an aerobic exercise program for the maximal aerobic benefit. That's determined by taking the number two twenty, minusing your age, and then multiplying that by zero point seven. That would calulate out to be about seventy percent of your maximal heart rate to get your maximal aerobic benefit from the exercise.
