Heart Rate high for Sweet Spot

[Bbt67]

These threads might help, a lot of discussion around this recently…

What sort of HR should I be hitting in sweetspot SSB MVI?

@vetleg Considering SS zone HR is 90-100% of LTHR and LTHR zone is 95-105% of LTHR you’re looking at 15BPM spread from the bottom of SS to the top of LTHR. So, no. All this is so dependent on a good reliable LTHR value from a good reliable test. For the record I have no idea if the ramp test can give you a LTHR. The 20minute-5%protocol used to find FTP is about the only way I’ve done it. Or average HR for an all out 1 hour effort.

Heart rate showing threshold during SS workouts

I’ve come to see that my HR has gone down significantly since doing SSBMV I and during it. Now I’m usually in tempo-range with my HR when doing SS-work. Even at the higher percentages. But still. 96-99% threshold will get my HR up to threshold. Even the higher end of SS-work will get it up just a beat or two into threshold-zone 4 of 5.
