Value of tracking HRV

Gentlemen, Do either of you see in value in tracking HRV and then applying it to make training decisions? I suppose that by tracking ‘session RPE’ over time (which I realize that your training spreadsheets now record) you could glean whether the average session is harder than intended and then sets could be paired back or a recovery block could be inserted. Would tracking the ‘session RPE’ be a fine substitute or am I missing something? Thanks!

No, we don’t recommend tracking HRV or using such data to make prospective changes to training, for a similar reason to why we don’t recommend using other sorts of self-data tracking like sleep trackers ( Placebo Sleep? | Barbell Medicine ).

We like session RPE and ACWRs.
