Heart Rate Zones are ranges of heart rates (as a percentage of either Max HR or Heart Rate Reserve) of increasing values that correspond to increasing levels of exercise intensity.
Lionheart 2.0 uses the Karvonen method of utilizing Heart Rate Reserve (i.e. taking into account a member's Resting Heart Rate and Max Heart Rate) to determine a person's heart rate zones.
The Heart Rate Zones and their respective formulas for Lionheart 2.0 are as below:
Zone 1 - Very light / Recovery
(60% or less) X HRR) + Resting HR
Zone 2 - Light / Easy
((60 - 70%) X HRR) + Resting HR
Zone 3 - Moderate
((70 - 80%) X HRR) + Resting HR
Zone 4 - Hard
((80 - 90%) X HRR) + Resting HR
Zone 5 - Maximum
((90% or more) X HRR) + Resting HR
The colors for each Zone in the F45 Training app and on the F45TVs for Lionheart 2.0 are as below:
