Keep the exercise identifiable
Record the exercise name and equipment. A machine press and a dumbbell press are different entries: comparing their loads directly can be misleading. Use the exercise library to check which movement you mean.
Record what you actually completed
For each working set, note the load and completed repetitions, rather than only the target. If you change equipment or technique, add a brief note. A consistent record makes your next session easier to interpret.
Review the context before deciding
Look at previous sessions for the same exercise. One unusually easy or difficult session does not explain the whole trend. Nemeo lets you log sets, repetitions and loads and uses your training history to provide progression guidance. Keep your own context in mind when considering a recommendation.
