Keep exercise variations and equipment settings visible in your triceps training history.
Give variations distinct names
A cable extension and a dumbbell extension should not silently share one weight record. Use a recognizable variation name.
State the weight convention
Record the displayed machine load or dumbbell value consistently. A note can identify the cable handle or whether a dumbbell figure means one implement.
Interpret the numbers narrowly
Sets and repetitions document the session. They do not measure arm size or identify an optimal exercise selection. Use your chosen program or qualified guidance for training decisions.
Distinguish cable and free-weight entries
A rope pressdown at a displayed 20 kg and an overhead dumbbell extension with 20 kg should be separate exercise records. The same number does not make them the same movement or resistance setup. Name the attachment when it changes the exercise you want to compare. If a dumbbell value represents one implement or a pair, write that convention once in a clear note and keep it consistent.
Make unilateral records explicit
If you record each arm separately, use an unambiguous left/right convention and retain unequal results rather than averaging them away. Check that your later summary is not accidentally counting a per-arm entry as a combined load. A short note can explain an equipment substitution or a shortened session. These examples organize a log; they do not prescribe triceps exercises, set counts, technique or treatment for discomfort.
