Strength training, PRs, and progressive overload
Praxis One logs strength work, personal records, and recovery so progressive overload stays attached to sleep and strain instead of a calendar.
Strength fitness progresses when the next session is slightly harder than the last one you actually recovered from. Praxis One keeps personal records and training strain next to sleep and recovery, so a heavy squat day is planned against how you slept, not against a spreadsheet that assumes every Monday is the same.
Hypertrophy, powerlifting, and general strength all use the same loop: log the work, watch recovery, add load when the score supports it.
