In this concise monologue, the speaker emphasizes that scientific research indicates the total weekly training volume—measured by the number of sets performed—is the primary factor for fitness progress.

The speaker underscores that the timing of individual sessions is irrelevant compared to the total volume delivered throughout the week.
