Adapt — Train What’s Ready

Field notes

Adapt builds each workout from two logged signals: how long ago a muscle group was trained and how sore the user reported it to be. Its progression rule raises the next working weight after a top-of-range result and holds it after a miss, while the log tracks estimated one-rep max trends, weekly volume, and personal-record milestones. The site also describes a max calculator that converts a recent hard set into an estimated 1RM and working percentages.
