Two weeks into the 8week high-volume polarized plan now. Recognize that AT is not supposed to be working with POL yet, but left it on to see what it recommends.
So far, AT seems to be recommending appropriate changes for VO2 and threshold workouts. I have approved all recommendations that have come up so far as they make sense based on my performance and how I answered the surveys. AT seems to work well for these specific workouts.
AT does not work as well for suggesting changes for endurance workouts. It is maybe better than what it sounds like it was a few months ago based on reading old comments (ex: some mention it would start subbing in SS workouts). However, it still often makes seemingly non-nonsensical recommendations. For example, doing a 1.5h z2 workout, rating it “easy,” and then having the recommendation come up to switch upcoming 1.5h Z2 workouts to easier variations. It also struggles a bit with it’s recommendations maintaining a logical progression in weekly total time of Z2 work, and in keeping appropriate progression of the weekly long-ride, though I wonder if these are related to a smaller library of Z2 rides for it to draw from.
As it stands, I think I trust AT to make appropriate changes to the VO2 and threshold workouts in the polarized plans, but ignore everything it says for the endurance workouts.
