Mr Z
An AI Coach to Break a Plateau

The same sequence, built into the AI
Most plateaus trace back to one of two things, recovery compromised by elevated cortisol, or a metabolism that's been running low for too long. Mr Z is built to check for both before suggesting any change to training volume.
What it recommends from there
If a reset is needed, the same protocol applies: two to three days off, sometimes longer, with protein lowered and low glycemic carbohydrates increased during that window. From there, the plan moves back into fat loss or recomposition with a system that's actually ready to respond again, instead of restricting further into the same wall.
