I’m not getting many adaptations, but have rejected maybe 1/5 to 1/3 of suggested. Reasons vary I guess, but in every case the changes haven’t been significant either adapting up or down.
IIRC, the rejections were from downgrades I felt the system was suggesting based on incomplete information.
Overall, I am changing things a lot. I was pretty hands on before, but am way less stressed about it now. It is much easier to decide in alternative workouts and I don’t worry about if I exactly stick to a planned workout - either failing it or super passing it. Just do my thing, take into consideration the info AT is giving me and have confidence over the long haul I’ll stay on track.
A month or so in and I’m feeling great about it. I’ve updated my plan goals a few times, worked in an outside hard group ride, swapped days without using the replace option and everything still seems on track to me. It really does just about nail the right difficulty of the workout - as in starting out I’m feeling it may be too easy, and by the end I’m just fine being done. That allows me to come in feeling strong each workout rather than dreading things.
So far the system tends to prescribe on the conservative side. That works out great for me. I can send it when I’m feeling good, confident that I won’t be far off if I have to back off on subsequent workouts.
All in all, for me AT is a massive moral booster more than anything else. Time will tell if that will help me break through a long standing fitness plateau I’ve been on.
