When it comes to me and my strange preferences I would trade AT for any decent plan builder not controlled by some things but rather combination of user preference and level.
I want to focus on my Vo2 max for 3 weeks, I choose time frame, zone with main focus, number of hours/wk or some other progression (could be even based on my previous weeks and training load). It could be expanded into secondary focus etc. This way I would have block that can be moved as a whole and used in the future as a template, but changed dynamically basing on my actualparameters like levels, tss, load ftp. This would be the most awesome feature. I would like some automation but with ability to use this automation as support of manual decisions.
But I am strange this way, as I like to have control over my training, and like to change things to see how my body will react. Maybe my biggest problem is the lack of features for “tinkers”, that like the process of choosing the workouts (if someone was playing Football Manager ever in his life know what I am talking about ;))
I have reflected that described almost old plan system, but with some twists. Maybe I am too old for this s… as someone has said
