Thanks. Yup, I’ve said that. And honestly now I would back up a step and just say “go 9/10 effort”, whatever that means to you, however you want to quantify it.
From what I’m reading and working on, I would suggest that we don’t need to max out intensity (VO2max, HRmax, Wmax, 10/10 RPE, whatever) in order to see improved performances a few weeks down the line. Consistent training in the target intensity zone (again, however you want to define that… just be above threshold) should be the main focus. Details beyond that are definitely important, but impossible to generalize. Applies to well-trained and recreational athletes, but your results will vary.
I’m very happy to debate (in good faith) the question of how close to 100% intensity is necessary! I think the answer is slightly lower intensity (as long as still within severe domain) in favour of slightly longer interval duration and greater volume/frequency/consistency. But I don’t think it’s a settled answer!
Can we clarify, if we want to talk about VO2peak in any given workout (which we should be talking about instead of VO2max). Then we can probably say we don’t necessarily need to reach our HRmax to be at our highest achievable VO2peak on the day?
As in, practical training advice can account for not hitting strict 100% HRmax or VO2max in a “VO2max workout” (however we want to define that), for it to be appropriate and effective?
