Get recent training volume

What your assistant is told

Training volume (Σ load × reps) over the last N weeks, with a per-week breakdown and workout count. The load is read through each exercise's loadMode, so a weighted pull-up counts the body it lifted and an assisted one counts what was left after the counterweight. Holds and carries have no tonnage (kg × seconds is not a volume), a band set's weight is an estimate of its tension and is never summed in either, and a bodyweight-based set with no weigh-in behind it adds nothing — in every case the set still happened.
