How can you determine what a healthy exercise heart rate is for you? There’s a simple formula that’s used to calculate your maximum heart rate. To determine maximal heart rate, simply subtract your age from 220. For example, if you’re forty years old, your maximal heart rate would be 180. Once you’ve calculated your maximum heart rate you can then determine your training zone.
If you’re just starting out with an aerobic exercise program, a healthy exercise heart rate would be around fifty to sixty percent of your maximal heart rate. For the example above, this would be an average heart rate of 90 to 110. An average exercise heart rate at this level is considered to be the low end of the fat burning range. It’s great for starters but you’ll want to build from this point to reach the aerobic training zone.
