When a program gives you a repetition range, your log can help you decide when to repeat a load and when to consider an increase. The method should follow the program you are using. It is a way to organize decisions, not a promise of constant progress.
Write the target clearly
Record the prescribed range and the number of working sets before starting. Alongside each set, enter the actual weight and repetitions completed. Keep the exercise setup consistent enough for those entries to mean something. If you change machines or movement variations, start a separate comparison instead of treating the numbers as interchangeable.
Earn the next step
Follow your program’s rule for increasing load once the target can be repeated with the intended technique. Use a manageable increment and expect the repetition count to change. Do not add weight solely because a new week has started. Repeating a load while improving control or consistency can be a sensible decision.
Keep exceptions visible
Note interruptions, equipment changes, or a session that felt unusually difficult. One entry rarely explains the whole trend. If the plan stops fitting your experience or recovery, ask for qualified coaching rather than endlessly forcing the same target. The best log makes the next choice clearer while leaving room for an honest assessment of how the training is going.
