Zone 2 computation

I do not think that has been asked before but whoop introduced zone training in their app. The HR zones do not match my garmin. They use this formula Target HR Intensity Zone = ((Max HR − Resting HR) × %Intensity) + Resting HR

If i use their zone system, my zone 2 limits are not the same as my garmin. For example 60 to 70 % of my 193 max hr puts me in 135 middle zone 2 while whoop is saying the beginning of zone 2 is 135 and I should be more using 140 value. I know it has to do with lactate build up. What is correct or it does not matter.

Zones are a made up concept for the most part :slight_smile: Their are a lot of different definitions and many analytics systems lets you define your own zone ranges. Garmin for example does. Zone 2 is what ever you want it to be. The recent popularity of the concept behind “zone 2” tie it to either a lactate level or your aerobic threshold. You have to decide how you define it. Set your own limits based on your goals. So you can use Whoops definition or garmins, or change garmins to match whoop… The world is your oyster.

thanks Alex. if i use 65% of my max hr, should i be good then ?

Most likely 65% is a safe number to be below AeT, so fits my definition of zone 2 very well. It should feel easy, like slightly harder than walking, you are almost not breathing much different than walking but still feels like more than walking, it’s probably perfect

Realize you may not need zone 2. I suggest it a lot for 2 reasons. It’s very low stress but enough to give you good fitness/health benefits. It’s especially good for people that don’t recover well or are doing so much they can’t recover from. I believe people should periodize, so you can have 2 months of hard work every 6 months or so, and then you might do less zone 2. Zone 2 creates a very good base. For general highest quality health zone 2 + weight lifting is likely the healthiest but not the best for cycling performance and fun.

i am trying to get angiogenesis. if i atart having lactate buildup if i understand, then that does not happen. if you exercise too lightly, same thing. how can you find the sweet spot riding for an hour and half to achieve this goal if you cannot test for lactate ? i am indeed looking for fitness/health outcome. i alternate 2 days a week with strength training. today is one of these days.

Lactate build up does not start until you get > FTP… You will get lactate below that it just won’t build up. Never heard of angiogenesis. You like finding interesting ideas :slight_smile: Sounds like you are heading in the right training from a health and fitness persective.
