Open a strength-training .fit file — sets, reps and no distance
A strength session is the .fit file that breaks tools built for running and cycling, because the fields those tools look for are simply not the point here.

No distance, and that is correct
A gym strength file has no GPS track, no pace, and often no distance at all — and a viewer built around those fields shows an almost empty activity. What the file does hold is the session’s structure: sets, reps per set, rest periods, and continuous heart rate. Judging a strength file by the running fields it lacks is like judging a swim by its cadence; the useful data is elsewhere in the record.
Rep counting is detection, not truth
Where a watch auto-detects reps, those counts come from recognising motion patterns and are approximate — a slow tempo, an unusual exercise, or a paused rep can miscount. The file stores what it detected; treating an auto-rep count as an exact log is trusting a classifier that is right most of the time and not always. Manually-logged sets, where present, are more reliable and the file marks the difference.
What you get from this page
This page opens your strength file on your device and surfaces the set, rep, rest and heart-rate fields it holds — the ones a running-shaped viewer skips — so a lifting session reads as full rather than empty.
