The tempting spreadsheet shortcut
Suppose a hypothetical workout contains three rows and two curls. Recording five identical biceps sets assumes that each row challenges the elbow flexors in the same way as each curl. That may not be true. Grip, technique, effort, and which muscle limits the row all matter.
Recording only the curls also leaves out genuine involvement in pulling. Both shortcuts lose information.
A two-column log can be enough
| Exercise | How to describe the work |
|---|---|
| Three row sets | Three pulling sets, with elbow-flexor involvement |
| Two curl sets | Two direct elbow-flexion sets |
This preserves the actual training without inventing a precise conversion factor. If a coach uses fractional set estimates, those estimates can be useful conventions, but they are not direct measurements of a muscle's adaptation.
Why consistency matters
Changing the accounting system can make weekly volume appear to rise when the workout did not change. Keep the convention stable when looking for trends.
Evidence-based weekly-volume targets are also based on particular study definitions and populations. They are not a reason to assign every supporting muscle a full set credit. Start with a clear record of exercises, effort, and repetitions; interpretation is easier when the original work remains visible.
