It’s about trends, don’t obsess on the day to day changes.
Just curious, what’s the explanation for unproductive?
I’ve been unproductive recently, because of high aerobic shortage, and off-the-bike stress.
That was Monday. Rides before that said to focus on rest and recovery. It started trending down after some anaerobic capacity work that ended a week ago. And work stress.
Two days later it’s still short on high aerobic but productive:
As the mental/physical stress from job and previous anaerobic workouts fades away.
My advice - either pause it, ignore it, or use it to help confirm trends.
