  • Find an exercise

    hevy.exercises.search

    Find exercise templates by name - for example "bench press" or "squat" - and get the template ids that workouts.log and exercises.history need. Scans up to 500 templates (built-in and your custom ones) and returns the closest matches. Read-only.

    Inputs

    Safety rules

    • Pick the template whose title and equipment match what the person actually did; ask when two fit equally.

  • Exercise history

    hevy.exercises.history

    Return every session in which you performed one exercise over a recent window, newest first: per session the date, workout title, set count, heaviest set, and volume - plus the heaviest set of the whole window. Use it for progress and personal bests. Read-only.

    Inputs

    • exerciseTemplateId (string, required) - The exercise template id, from workouts.list or exercises.search.

    • setCount (number) - Sets in the window.
    • heaviestSet (object) - {weightKg, reps, startedAt} for the window, or null.

    Safety rules

    • Report only numbers the history returns; never invent a personal best.

  • List body measurements

    hevy.measurements.list

    Return your newest body measurement entries - weight (kg), body fat (%), lean mass, and any girths you logged - newest first. Read-only.

    Inputs

    • limit (number) - How many entries to return, 1-10. Defaults to 10.
    • page (number) - Which page of entries. Defaults to 1.

  • Log a body measurement

    hevy.measurements.log

    Record one body measurement entry for one date - weight (kg), body fat (%), and/or lean mass (kg). Hevy keeps one entry per date: if that date already has one, nothing changes and the operation reports it.

    Inputs

    • date (string) - The day of the measurement as YYYY-MM-DD. Defaults to today (UTC).
    • weightKg (number) - Body weight in kilograms, 1-500.
    • fatPercent (number) - Body fat percentage, 1-80.
    • leanMassKg (number) - Lean mass in kilograms, 1-400.

    Returns

    • date (string) - The date the entry was logged for.
    • logged (boolean) - True when Hevy accepted the entry.

    Safety rules

    • Log only a value the person stated; never estimate or carry a value forward.
    • Convert pounds to kilograms before logging (1 lb = 0.4536 kg) and say so in the reply.

  • Log a workout

    hevy.workouts.log

    Create one workout in your Hevy account from exercises and sets. Each exercise needs a templateId (find it with exercises.search) and at least one set with reps, weightKg, distanceMeters, or durationSeconds. Times default to a session ending now; the workout is private unless isPrivate is false.

    Inputs

    • title (string, required) - The workout title, for example "Push Day".
    • exercises (object, required) - JSON array of exercises: [{templateId, notes?, sets: [{type?: normal|warmup|dropset|failure, weightKg?, reps?, distanceMeters?, durationSeconds?, rpe?}]}]. At most 30 exercises with 30 sets each.
    • durationMinutes (number) - How long the session took, 1-600 minutes; used when startTime is not given. Defaults to 60.
    • startTime (string) - ISO 8601 start time. Defaults to endTime minus durationMinutes.
    • endTime (string) - ISO 8601 end time. Defaults to now.
    • description (string) - Optional workout notes.
    • isPrivate (boolean) - Keep the workout off the Hevy social feed. Defaults to true.

    Returns

    • id (string) - The created workout id.
    • title (string) - The workout title as saved.
    • startedAt (string) - Saved start time (ISO 8601).
    • endedAt (string) - Saved end time (ISO 8601).
    • exerciseCount (number) - Exercises logged.
    • setCount (number) - Sets logged.
    • isPrivate (boolean) - Whether the workout was saved as private.

    Safety rules

    • Log only what the person said they did; never invent exercises, sets, weights, or reps.
    • Find each templateId with exercises.search first; never guess an id.
    • Log a workout once per request - a retry creates a duplicate.
    • Keep isPrivate true unless the person asks to share it.
