Calculate Your Target Heart Rate
Your target heart rate is a range at which your body is getting enough of a workout to get stronger, but without overdoing it. For most healthy adults, a target heart rate between 50 and 75 percent of your maximum heart rate. The rate changes depending on how old you are.
To find your Target heart rate:
First subtract your age from 220 to get your maximum heart rate
For the Low End, multiply that number by .5
For the High End, multiply that number by .75
If you are someone that is just starting out, you will want to be in the lower part of the range. As you feel more confident you may increase the range with you reach increased fitness levels.
