What file should I give the AI?
The JSON export works well because it's structured and complete. You can also paste in a CSV.

In Workout Exporter, open a workout, tap Export, and choose JSON (full raw data).
Save it to Files, or AirDrop it to your Mac.
Start a chat and attach the JSON file.
Ask for a summary, an effort assessment, or a comparison — then iterate.
