Training and nutrition are difficult to evaluate from memory. Logbook stores exercises, sets, reps, food, macros, and bodyweight so you can compare current results with previous days and sessions.
The record does not need to be perfect to be useful. Consistent entries show where workouts progressed, where nutrition missed target, and how bodyweight changed.
Daily weight can move for reasons that have little to do with body-fat change. Keeping a longer record makes it easier to focus on the trend. Logbook connects that progress view with the workouts and nutrition habits that influence it, so the number is not isolated from the work behind it.

Keep your training sessions organized and review previous performance before you repeat a movement.
