Log a superset back-to-back

You finished the second exercise without setting anything down — straight from curls to tricep extensions, then a breath of rest, then back to curls. Three rounds of the pair. The whole thing is one entry, not six.

What the agent needs to hear

Behind your sentence, the agent works backwards to four pieces: the two exercises in the pair, reps per exercise per round, the weight on each, and how many rounds you did. The active session and the exercise queue narrow this down — if your routine had the pair planned, naming them is enough. If you went off-script (« paired curls with tricep extensions — wasn’t planned »), the agent attaches the cluster to both exercises in your session and creates entries for any that weren’t already there.

The agent shows you a card with the pair on top and each round listed underneath, reps and weight per side. Two columns, N rows. You confirm and both exercises get the rounds attached at once.

Reps, weight, and rounds

By default, the agent assumes the same reps and weight across all rounds. « 12 and 12, three rounds at 15 and 20 » means three rounds of 15 kg curls for 12 + 20 kg extensions for 12. If anything changed between rounds — the second curl dropped to 10 reps because you fried out — say so: « last round of curls was 10, not 12 ». The agent adjusts that one cell and leaves the rest alone.

If the weights varied per round, list them in order: « curls 15, 15, 12.5; triceps 20, 20, 20 — three rounds, 12 reps across ». The numbers map to rounds in sequence. As always, numbers override defaults and units stick.

What the pair preserves

A superset is one cluster of two exercises, logged as N rounds. The shape matters: logged as a pair, the system knows the two exercises were performed back-to-back with no rest between them, and the rest period belongs to the round, not to either exercise alone. That changes how fatigue, density, and time-under-effort read downstream.

PR detection still works per exercise — the heaviest curl round still counts, the heaviest tricep round still counts. What the pair adds is the density signal: three rounds of a superset is denser work than the same total volume done as six separate sets with rest between each. Logging the cluster shape is what lets that signal exist.

When the agent gets it wrong

Read the preview the way you’d check a partner’s tally before signing off. If the rep count on one side is off, say which side: « the curl reps were 10, the tricep reps were fine ». If the agent attached reps to the wrong exercise (it read « 12 and 10 » in the wrong order), call it: « 12 was the curl, 10 was the tricep, not the other way ».

If the agent split your sentence into independent sets instead of a paired cluster, push back: « that’s one superset, not separate sets ». If you forgot a round — three rounds done but you only said two — add it: « actually I did one more round, same numbers », and the cluster grows.

What makes the log worth keeping

Three things decide whether this superset helps you later: the pair is preserved as a cluster (so density and back-to-back fatigue read correctly), the reps land on the right exercise (so each exercise’s PR ledger stays honest), and the rounds match what you actually did (no invented rounds, no skipped ones). The system uses these for density, fatigue, per-exercise progression, and weekly volume; logging a superset as six separate sets is the cleanest way to lose the density signal entirely. Say the pair the way you trained it — both exercises, rounds in order — and let the agent group them.
