Returns completed workout sessions (with every exercise and set) from the last N days, newest first. Use this to see what the user actually did recently. Each session includes difficultyRating (1-5, how hard the user said the workout felt right after finishing it, 5 being extremely hard) when available - use it alongside volume/reps trends to judge whether intensity or volume should change.

Returns every logged set for one specific exercise over time (most recent first), so you can see progression (reps/weight trend) for that movement.

Aggregates sets/reps/volume (reps x weight) over the last N days, grouped either by muscle group or by exercise. Use this to spot over/under-trained muscle groups before proposing a workout.

Returns days since each muscle group was last trained, plus sets trained this week, so you can judge whether a muscle group is ready to train again.

Returns the user's exercise library (name, muscle groups, equipment, category, movement pattern, whether it has a custom photo), optionally filtered. Use this to know what exercises/equipment are available when proposing a workout. Note: category and movementPattern are null when the exercise has no stored value, and in practice are unreliable even when set (this app's exercises are largely left at the defaults "compound"/"push", so a hinge or isometric movement may still report "push"). Judge movement patterns from the exercise name and muscleGroups instead of trusting these two fields.

Returns the user's full profile: training preferences (goal, experience level, available equipment, days per week, session length, injuries/limitations) PLUS body/personal info (height, weight, age, biological sex, body type, fat distribution, activity level) and food preferences (dietary restrictions/allergies, cuisine/food notes, nutrition goal, daily calorie/macro targets). Always check this before generating a workout AND before generating or adapting a nutrition plan (see save_nutrition_plan).

Adds a new exercise to the user's library, optionally with a photo. Note: the new exercise's category/movement pattern aren't set by this tool (a known limitation) - it'll show up on the user's devices with default values (compound/push) until edited from the app.

Updates an existing exercise's name, muscle groups, equipment, and/or photo (fuzzy-matched by name, or exact by id). Category and movement pattern can't be changed by this tool (a known limitation) - edit those from the app.

Deletes an exercise from the user's library (fuzzy-matched by name, or exact by id).

Returns the user's saved workout templates (training session blueprints) with their full ordered exercise lists - target sets/reps/rest plus tempo, intensity, suggested weight and superset grouping for every slot. Each slot comes back in exactly the shape save_workout_template/update_workout_template accept, so you can read a template, change part of it, and write it back without losing anything. Use this before update_workout_template - that tool replaces the whole exercise list, so you need the current one first.

Creates a NEW workout template (a reusable training session blueprint) with an ordered list of exercises, each with target sets/reps/rest and optional tempo/cadence, intensity (RIR/RPE), suggested working weight, and superset grouping. Exercises must already exist in the library (see get_exercise_library, or create_exercise first). To change an existing template instead, use update_workout_template - creating a duplicate and deleting the old one loses its link to past workouts.

Edits an existing workout template in place - its name, estimated duration, and/or its exercises - keeping the template itself, so its link to past workouts in history (and to any periodization cycle) survives. This is the tool for requests like "swap the first three exercises of my chest day for cable variations" or "add a set to every exercise". IMPORTANT: exercises REPLACES the entire exercise list, so call get_workout_templates first and send the full list back with your changes applied; omit exercises to change only the name/duration. Prefer this over delete_workout_template + save_workout_template.

Renames an existing workout template in place (fuzzy-matched by name, or exact by id). Doesn't touch its exercises.

Deletes a workout template and its exercise slots (fuzzy-matched by name, or exact by id). Does not delete workout history/sessions that already used it.

Creates a periodization cycle (a named training block, e.g. a hypertrophy or strength block with a start/end date) and optionally links existing workout templates to it. Note: the cycle's training phase isn't set by this tool (a known limitation) - edit that from the app.

Returns the single active nutrition plan - the week's days and meals with full recipe details (ingredients, instructions, calories/macros) - or null if none has been generated yet.

Creates the week's nutrition plan. IMPORTANT: there is always exactly one active plan - calling this REPLACES whatever plan currently exists (deleting it and its days/meals) rather than creating a second one. Use this to generate/regenerate the whole week; for smaller tweaks to specific meals or days, prefer update_nutrition_meal / update_nutrition_day / update_nutrition_plan instead so the rest of the week isn't thrown away. Before calling this, check get_training_preferences (body stats + food preferences/restrictions) and ideally get_workout_history/get_recovery_status so the plan reflects the user's actual training and goals.

Adapts plan-level metadata (name, notes, start date, and/or the generation prompt) on the active nutrition plan in place, without touching its days or meals.

Adapts one day of the active nutrition plan: rename/re-note it, and/or replace its whole meal list - without touching other days. Use update_nutrition_meal instead for a single-meal tweak (e.g. just swapping one recipe).

Adapts a single meal's recipe, ingredients, instructions, macros, and/or time within the active nutrition plan, without regenerating the rest of the day or week. The main tool for requests like "swap Tuesday's lunch for something else" or "make Wednesday's dinner higher protein".

Deletes the active nutrition plan and all its days/meals.
