Agree with all you stated. I’ll just add that regardless of whether a person uses TN or a plan they have to have some perspective of their own fatigue level and life stress and dial things back, take a rest day/week if necessary. AT only knows so much based on your workouts and survey responses. It doesn’t know if you’ve been sleeping poorly or maybe you’ve got some other stress in your life that’s going to contribute to your fatigue.
There can definitely be a fine line between challenging yourself with tough workouts/plan vs absolutely burying yourself each and every workout.
Whether it’s TrainerRoad or some other app, I don’t think anybody should just 100% blindly do all the workouts without pausing to truly evaluate your fatigue level.
