Sets and repetitions: understanding the numbers you record
A target describes the plan; completed repetitions describe the session.
Two different units
A repetition is one counted performance of the movement. A set groups repetitions together before a break. Three sets of ten is a planned structure; it does not prove that thirty repetitions were completed.
Keep the result separate from the target
If a later set ends at eight repetitions, record eight. Replacing it with the planned ten makes the next comparison less useful. In JJ FIT, mark the sets you finish and review the completed-set record when ending the session.
The same numbers can describe different work
Equipment, resistance, movement and rest affect the task. A line reading three by ten needs that context. Copying another person’s set and repetition scheme does not establish that the workload is appropriate for you.
Warm-up work needs context
Warm-up sets may help prepare for the session, but their purpose differs from a working set. A total set count should not erase that distinction. Keep an understandable convention when using a log that does not provide separate labels for every set type.
Use totals carefully
More completed sets is not automatically a better session. Keep the record accurate, compare similar exercises and use your goals to interpret it. An app summary cannot replace coaching about technique or an assessment of persistent symptoms.
