Personal records that update live, on the screen, mid-set.
Follow a written plan or log a free session with no plan at all — every set, every rest timer and every PR live on screen during the lift, not reconstructed afterward from memory.
Live workout screens
Sets, reps, weight and rest timers on screen during the session — the record is built as you train, not typed in after the gym.
Real personal records
A PR is only ever a genuine best on your own bar, tracked automatically as you log, never a manufactured milestone.
Protein that tracks your real weight
1.6g per kilogram of the bodyweight Health measured this morning — the target moves as you do, not a number set once and forgotten.
Recovery before the next hard session
Recovery, strain and sleep debt are visible before you decide whether today is the day to push a heavy set or hold back.
What Life OS doesn't try to be
It is not a programmed strength-coaching system with periodisation built by a certified coach — if you want a written program, you bring your own or build one with Custom Plan; Life OS logs it and tells you the recovery context around it.
