HR zones are how we identify the impact of your cardio.
Each zone has a purpose, and we want to make sure it aligns with your goals.
Trail runners will likely spend most of their cardio training in zones 2-4.
To learn what your bpm (beats per minute) you’re looking for based on percentages, take 220-your age.
For example,
I’m 28.
My max HR is calculated as 220 - 28 = 192
So if I’m looking to stay in Zone 3, I’m going to take,
192 x .7 = 134 bpm
192 x .8 = 154 bpm
My Zone 3 is 134-154 bpm
BOOM.
