Zone 2
Zone 2 training sessions are perfect time to tell your body to use fats and carbohydrates as a fuel source not predominantly carbohydrates which we usually do in a typical TWRs.
Zone 2 Heart Rate Formula
Since your zone 2 heart rate is based on a percentage of your max heart rate, the first step is to calculate your max heart rate.
Max Heart Rate = 220 – Age in Years.
Then, you can multiply your max heart rate by 60-70% to find your zone 2 range.
Zone 2 Range = (max HR × 0.6) to (max HR × 0.7)
Coach Chris Hinshaw describes ‘Zone 2’ very briefly in this video.
