I’m wondering if there is any way to set the lower HR zones at “resting HR” rather than the physiologically impossible minimum HR value of Zero? (assuming most athletes are not training while dead of course 
) I have tried manually altering zones but it will not let you adjust the start of Z1.
I believe this was discussed and requested previously. I think short answer is cannot. Something about how it’s already baked in the system design.
You can possibly search in the forum but I think that’s what I read. May be wrong but….
Thanks for that. That seems about right as I haven’t found a way myself to alter anything.
Thanks again.

The lowest HR zone starts from 0 because Intervals needs to assign every datapoint in one of the zones. That’s how Intervals works regarding Total Time and Time in zones.
