This will give you ranges of beats per minute for each percentage of maximum heart rate. Then pre-determine the target zone ...

220-age has been the gold standard for figuring out maximum heart rate and heart rate zones. The problem? It isn’t even based ...

The truth is that age alone doesn’t determine a person’s max heart rate, so no matter what numbers you use to create an age-based formula, you’re just not going to get a useful result.

Because our maximum heart rate (MHR) changes as we age, our heart rate target zones change too. This accounts for physiological changes that occur as we get older, explains Milica McDowell, DPT.

Discover what's considered a normal heart rate while walking slowly, how to find your target heart rate zone, and ways to ...

Zone 4 (85-95% of max heart rate): This is where the intensity ramps up. You're working hard and can only sustain it for up to about 15 minutes (depending on where you fall in the 85-95% range).

Your maximum heart rate, which can be roughly estimated based on your age, is a measure of how fast your heart beats during intense exercise.

For example, a 20-year-old’s max heart rate would be 200 in theory, but for anyone that age, it could range in either direction by 24 beats, he says. Their max heart rate could be anywhere ...
