First, a simple formula to find your zone 2 heart rate: Subtract your age from the number 180. ... and heart rate reserve to help you calculate your target heart rates for each of the five zones ...
The Karvonen method factors in resting heart rate (HR rest) to calculate target heart rate (THR), using a range of 50–85% intensity: [54] THR = ((HR max − HR rest) × % intensity) + HR rest. Equivalently, THR = (HR reserve × % intensity) + HR rest. Example for someone with a HR max of 180 and a HR rest of 70 (and therefore a HR reserve of ...

There are different ways to define CI. One common threshold is not being able to reach 80% of age-predicted maximal heart rate (APMHR), which is said to be 220 – age. Another definition is not being able to reach 80% of the expected heart rate reserve, that is, the difference between the individual's resting heart rate and APMHR. [1]
Those are times to seek out help because it may not be a reflection of your resting heart rate, but an abnormal heart rhythm that should get evaluated.” Having a pulse over 100 bpm is called ...
A child aged 1–3 years old can have a heart rate of 80–130 bpm, a child aged 3–5 years old a heart rate of 80–120 bpm, an older child (age of 6–10) a heart rate of 70–110 bpm, and an adolescent (age 11–14) a heart rate of 60–105 bpm. [12] An adult (age 15+) can have a heart rate of 60–100 bpm. [12]
[citation needed] The heart rate formula most often used for the Bruce is the Karvonen formula (below). A more accurate formula, offered in a study published in the journal, Medicine & Science in Sports & Exercise, is 206.9 - (0.67 x age) which can also be used to more accurately determine VO2 Max, but may produce significantly different results.
Some studies measure exercise intensity by having subjects perform exercise trials to determine peak power output, [4] which may be measured in watts, heart rate, or average cadence (cycling). This approach attempts to gauge overall workload. An informal method to determine optimal exercise intensity is the talk test.
