# Determine Your Maximum Heart Rate More Accurately With This Formula

2

Since the 1970s, the general suggestion for determining your maximum target health rate has been to subtract your age from 220. However, as a New York Times article points out, that formula is not particularly accurate.

The traditional formula underestimates your heart rate regardless of your age, but it starts getting inaccurate if you’re older than 30. Unfortunately, the more accurate formula is a lot harder to remember:

Instead, according to his group’s recent examinations of 3,320 men and women between the ages of 19 and 89 who participated in a wide-ranging health study in Norway, a better formulation for both sexes would be 211 minus 0.64 per cent of age. Should your brain, like mine, revolt at the thought of the maths required to determine maximum heart rate with those numbers, Dr. Wisloff’s lab has posted a simple calculator online.

Of course, exercising in any way is helpful, and you don’t always need to know your maximum heart rate (it is helpful for certain training like the seven-minute workout though), but it’s often helpful to see how hard you’re really pushing yourself.

Pretty sure it should be 64% of age.
And what is with the maths hate? 64% is about 2/3, maybe minus one or two, 3 if you’re over 100. You wouldn’t say “there’s a one syllable word version for people whose brain can’t handle multiple syllables”

Maximum Heart rate is different for everyone even if you are the same age.
Elite sport coaches and sports scientists have knowledge of how to do it.
It is very stressful so make sure you are with someone who knows what they are doing and that they have the equipment to measure it.
If you are average then the average calculation will give you average MaxHR.
