Muscles
Every muscle wears its rank.
Each group is coloured by the tier its lifts have earned, from Wood up to Legend.
With flare adjustments turned on, a flare check-in triggers one automatic response: that week's training volume drops by 20%, starting the day after you log it. A missed-workout suggestion shows up separately for you to accept, and your macro targets hold on their own terms.
