How to Log Timed Exercises Without Inventing Rep Counts

When an exercise is measured by duration, record the actual time and its unit. A 35-second hold should remain a 35-second hold; it does not need to become 35 reps to fit a familiar logging layout.

Keep the exercise variation, interval number, and any measured load beside the duration. If your tool does not offer a duration field, a clear note or a separate worksheet can preserve the measurement without giving an unrelated numeric field a new meaning.

Choose an unambiguous time format

Use seconds for short efforts or write minutes and seconds explicitly. “1:30 min:sec” means 90 seconds. “1.30 minutes” is a decimal value and equals 78 seconds, so it is not the same entry.

A column headed duration_seconds avoids that ambiguity in a spreadsheet. For longer entries, keep the displayed format and its meaning together. Do not mix 90, 1:30, and 1.5 in an unlabeled column and expect a later calculation to interpret them correctly.

Keep each effort on its own row

Consider a fictional session containing three timed holds:

• Effort 1: 35 seconds, completed continuously.
• Effort 2: 32 seconds, completed continuously.
• Effort 3: 28 seconds, completed continuously.

Their total work time is 95 seconds. Their longest continuous effort is 35 seconds. These are different summaries, and neither means a continuous 95-second hold occurred.

Write the side or position when it matters. Left and right efforts should be identifiable instead of combined into an unexplained duration. Similarly, changing a setup between efforts needs a note before you compare results.

Separate work time from rest time

An interval session can have work duration, rest duration, and overall elapsed duration. Keep those fields distinct. Concept2's logbook documentation explicitly distinguishes interval work time from rest time; the same distinction is useful in your own manual notes.

For example, two fictional work intervals of 60 seconds separated by 45 seconds of rest contain 120 seconds of work and 165 seconds from the first start to the final finish. Adding a rest period after the last interval changes the elapsed-time definition, so say whether you counted it.

The worksheet includes seconds as the unit. It does not connect to a monitor or synchronize with Gymr; copy only values you actually measured.

Mark interruptions rather than merging them

If a timer shows 40 seconds but you paused halfway through, record whether the timer continued. Two 20-second efforts separated by a pause are not a continuous 40-second effort. Keep separate rows or label the interruption and the limits of your measurement.

If you forgot to start the timer, mark the duration unknown rather than deriving it from the planned target. Our guide to missing entries shows how to retain known details without guessing.

Compare like with like: the same exercise variation, unit, and definition of continuous work. A useful workout log preserves the measurement you made, even when that measurement is time instead of repetitions.
