Separate the target from the result
The range belongs to the plan. The repetitions you actually complete belong to the record. If a programme lists eight to twelve repetitions, an entry of ten, nine and eight tells you something that copying eight to twelve three times does not.
Read the surrounding instructions as well. The number of sets, the rest arrangement and any guidance about stopping all contribute to the task. A range on its own is not a complete prescription, and an example in an article is not a personalised programme.
If you are unsure what counts as a completed repetition for the movement, ask for a demonstration and feedback. Counting should follow an appropriate, repeatable movement, rather than encouraging you to shorten it just to reach a particular number.
Do not force the upper number
The top of a range is not a command to continue regardless of control. If the exercise stops resembling the version you were taught, the number in the notebook becomes less meaningful. Likewise, pain is not an instruction to finish the remaining repetitions.
Some programmes use a range as part of a progression method: establish consistent work within the range, then change the resistance according to stated criteria. Others use ranges differently. Find out which method your programme uses instead of assuming that every successful set means a heavier load next time.
A difficult final set may finish with fewer repetitions than the first. Record the sets separately. An average can hide the pattern and makes it harder to discuss the session with a coach.
Check how unilateral work is written. Ten repetitions on each side is different from ten divided between sides. A coach may also specify how the sides alternate. Recording only a total can conceal that detail, so label it explicitly until the convention is familiar.
If you lose count, record the uncertainty rather than adding repetitions to make the entry look certain. Counting errors happen, especially with an unfamiliar movement. The next improvement may be paying attention to the count or using a clearer logging method, not increasing the amount of work because the arithmetic became unclear.
Ask the missing questions
If the programme gives only a range, useful questions include what level of effort is intended, when the set should stop, and how many sessions should support a change. Also ask what to do if the available equipment jumps to a much heavier weight.
Do not solve the final question by inventing a completely different range each week. That creates moving targets. A suitable adjustment can be agreed without pretending the equipment offers increments it does not have.
On a machine, confirm whether the displayed setting describes resistance or assistance. This matters particularly when interpreting whether moving the pin represents making the exercise harder or easier.
Keep the example in its place
Eight to twelve is used here to explain notation, not to prescribe a universal range. Different exercises and goals may use different arrangements. The transferable habit is to know what the programme asks, record what occurred and apply its progression instructions consistently.
If you cannot explain what the range means for your next set, pause long enough to get that explanation. A short clarification is more valuable than several weeks of accurately recording a task you have misunderstood.
